Description

The present invention generally relates to control systems

  computer-based software for machine tools and is particularly concerned with the

  graphical visualization of information related to

  such tools and the machining process. Numerical control systems for controlling machine tools according to the execution of programs recorded in a computer are well known. Such systems control the machining operation under the action of one or more coin programs that are stored in a memory after being

  loaded into memory by means of, for example, a ban-

  perforated. On request, the part program makes

  perform a series of manufacturing steps at the machine.

  When, for example, the machine comprises a cutting tool, the relative movement between the machined part and the cutting tool is normally carried out along three mutually perpendicular axes, in accordance with the part program which imposes the movement of the tool cutting. In addition, a computer numerical control system can be designed to control other functions such as tool changes, spindle speed, coolant flow, pallet selection, and generation of spindles. messages and graphics. The number and type of functions vary considerably depending on the type of machine tool

  which is ordered. In the past, we performed the

  using specialized cable circuits that operate

  dependent on conditions detected on the machine-

  tool and orders contained in the part program.

  More recently, however, the logic associated with machine tool control systems has been incorporated into a computer system using a set of recorded programs (i.e.

  achieve the overall order. The software is special-

  adapted to a particular application and can easily be modified on demand to meet specific needs. The addition of a programmable control to a digital control system provides a number of advantages, the first and most important of which is that it is sufficient to reprogram the command for him

  to operate with a particular machine tool

  die. In addition, the programming by the user is

  relatively easier, because of the kind of instructional

  which is normally used and characteristics

  which are normally available.

  A CNC, or simplex

  CNO, intended to control the functioning of the

  of a machine tool, may include two separate software packages

  res, namely the "numerical control logic", which is called the numerical control software, whose content is more or less fixed, and the "control logic of

  machine ", which is called the LCM program, which is modified

  ble and can be adapted to a particular machine tool.

  In industry, this adaptation is usually done by the specific equipment manufacturer (OEM). The numerical control software controls the manufacture of the parts, the movement according to the axes, the

  visualization on a cathode ray tube and other

  while the LCM program essentially, if not exclusively, controls the operation of

  the machine tool. U.S. Patent Application

  No. 415,041 filed on September 7, 1982 further describes a

  interface software, called an Adaptation Window.

  which consists of a group of programs,

  input / output networks and state indicators that ensure

  the connection between the numerical control software, the LCM program and the machine tool. Using an adaptation window provides the constructor

  specific equipment, or to the customer, a great deal

  plesse in the adaptation of a CNC to a particular machine tool. In one of

  its aspects, the invention uses a window of adapta-

tion.

  Once the numerical controls by computer

  have been programmed and function, they replace

  function automatically and virtually without the intervention of the operating staff. It is however necessary from time to time that the operator (or others) can quickly discern operating results, machining data, machine conditions, etc. In short, it is necessary that he

  There is easy communication between the digital

  only by computer and the staff who take care of the

  controlled cessation. In a numerical control by computer

  Characteristic type, a considerable part of this communication is done by a visual presentation on a cathode ray tube. Most of the information presented, however, is in the form of a text that must be read in its entirety to be fully understood. There remains therefore a need for a graphic aid, so that the operating personnel can very quickly and easily know operating conditions such as the speed of the spindle, or the cumulative use time of a tool, in

  just glancing at the screen of the cathode

than.

  The object of the invention is therefore to provide a

  upgrading to digital control systems for

machine tools.

  The invention is more particularly intended to provide an improvement to means for presenting information on a graphic display device for a digital control system.

  by computer, so that machine operators

  tool, maintenance or other personnel can easily and quickly discern the conditions of

operation of the machine tool.

  Briefly, we reach the previous goals

  as well as others in a digital control system

  than by computer, through the use of a new

  of subprogrammes incorporated in the part of the pro-

  machine control logic (LCM) program that is specially accessible for control adaptation

  computer-based to a particular machine tool

  re. The subroutines are executed when the machine operator requests the display of a status information display page of the machine. The

  subprograms include a routine intended to initiate

  tialize a predetermined graphic visualization to

  from the software visualization control files

  digital control sky. This is followed by a second routine that is run periodically when the graphics visualization is active, to update

  dynamically the graphic information that is visible

  Lisée. During each of the two routines, one or more of six "trace" procedures are called to produce

  the desired graphic visualization. These procedures

  take the movement of a graphical cursor to a given position on the cathode ray tube screen, the drawing of a line, the drawing of a rectangle, the drawing of a

  arc, the outline of a circle, the filling of a pre-

  determined and erasing an area, which may include

  the entire viewing screen.

  By combining these procedures, a graphical representation of physical quantities can be created on the screen of the CRT. These graphics are of a form that the observer can quickly understand. In some cases, we can give them a shape similar to

  that of analog measuring devices. As an example

  By combining two adjacent arcs, you can create an analog display of the speed of a spindle as a percentage of the maximum speed. In such a case, the cursor is brought to a specific position, a first arc is then drawn whose length represents the actual speed of the spindle, and a trace is then drawn.

  second arc, contiguous to the first. The two arches represent

  together, the maximum speed of the spindle. As the speed of the spindle changes, the angles of the arcs vary mutually. The impression obtained is enough

  similar to that corresponding to a tachometer with

  analog chage. Note that we can create graphs

  segments, pie charts and various

other forms of graphics.

  Referring now to the drawings, and more particularly to FIG. 1, there is shown, for purposes of illustration, the functional environment in which the invention is implemented. Figure 1

  shows, for example, a digital control system

  only by computer (CNO) intended to control a machine-

  tool 10 and which includes three elements of primary material

  cipaux. These elements are as follows:

  18, and a keyboard 20 having special function keys for inputting sets of information, which are called files, and for subsequently controlling the reading of the file information in a well-defined manner. known, for the execution of

programs. -

  The machine control station 14 comprises a set of manual controls and pushbuttons

  22 used for the functions performed by the opera-

  the machine, including mode selection, offset access, step advance, spindle speed, feedrate, etc.

  The functions performed by the communication system

  Numerical control: by computer shown in Fig. 1 are determined by internally registered programs known as computer numerical control software. Digital control software by

  computer consists of three sets of programs

  my differences, as shown in Figure 2, and it

  takes the numerical control logic 24 (called

  ra hereinafter the numerical control software), the window

  LCM 26 and the machine control logic 28 (which

  will call here the LCM program). The software of

  digital control 24 orders the production of parts, the movement according to the axes of the machine and the presentation

  messages for a cathode ray tube. The software of

  digital control constitutes a fixed or permanent part

  of the CNC system that the use of

  the user can not normally change. The LCM program specifically controls the operation of the machine tool and consists of a large number of subprograms contained in modular sections

  called modules, which allow the equipment manufacturer to

  (OEM) to adapt the system to the use of

  tor. The LCM 26 window consists of software, such as

  that described in U.S. patent application.

  No. 415,041, which allows the LCM program 28 to communicate with the digital control software 24 and

  which gives access to the inputs and outputs of the machine-

tool 10.

  As Figure 3 shows more

  the LCM 28 program consists of two

  The fixed LCM 30 and the adaptation LCM 32. The adaptation LCM contains the programs for controlling the operation of the machine tool 10, using the LCM window software 26 to provide the necessary interface with the machine. machine. It's the LCM of adaptation 32

  which is specially designed to adapt the numerical order

  by computer when ordering a particular machine tool. The fixed LCM 30 is on the contrary a software

  whose fundamental function is to control and com-

  the devices intended for the operator in the

  machine control station 14 (FIG. 1), and it is used

  without any modification in most applications.

  tions. The LCM window 26 is constituted by a series of window procedures and functions, 34, by state indicator networks 36 and by input and output networks 38 which, for the most part, can not be changed, so that the integrity of the numerical control software can not be compromised by

  and any procedures programmable by the user

  which are programmed in the LCM 28 program.

  The digital control software 24 is constituted by a set of routines for controlling the manufacture of parts, 40, motion along the axes, 42, and visualizations for the operator, 44, which also provide programs for controlling movement

  spindle, timers, mathemati-

  and machine configuration data. The routs

  visualization 44 are of particular interest

  relate to the invention to the extent that they include routines that allow the adaptation LCM 32 to select or "call" selectable display page routines of the digital control software,

  in order to visualize for the operator, on demand, the

  desired machine state formation.

  Before describing the invention in detail, it is necessary to

  The structure of the LCM program 28 will briefly be ignored. The LCM program consists of an executable sequence

  subprogrammes expressed in a programming language

  high-level representation that resembles a natural language

  like English. This language, called Programmable Control-

  Language (PCL) consists of a group of associated data and instructions, similar to PASCAL, which are

  intended for the performance of a particular operation

  re. Subroutines are created separately and can be used as often as is necessary to execute either a procedure that performs an operation or a function that performs an operation and returns a value. Each program has an identifier (called a "call") which, when encountered,

  causes the execution of the program. Each sub-

  program is introduced by a declaration followed by the

  constants, variables, networks or data types listed

  contained in it. For a numerical control system

  tion is particularly useful when it is

  used in combination with a numerical control system

  Mark Century 2000, but it appears that

  clearly that the invention is not limited to this system and can equally well be used with

  other digital control systems.

  Now considering Figure 4, we note

  the adaptation of an MCL 28 program for the machine-

  Tool 10 begins with the introduction by a system designer of a series of PCL routines, designated

  46, in the digital control system

  than by computer, by means of the keyboard 20 of the digital control station 12, in which these subroutines are applied to a file editor 48. The latter transforms them into PCL files which are recorded in

  a memory, not shown. PCL files are also

  applied to a PCL 52 compiler in which they are then translated into machine code and are registered

  in the form of a machine code file 54.

  In the program processing, the machine code files are then applied to a linker 56 which produces a single machine code file 58. The chained machine code file is then applied to an implementation module 60 which assigns addresses. in

  a RAM, not shown, to the information contained in

  nude in the output file of the linker, and which creates a new file 62 containing the assignments in RAM. The information from the linker output file is the final version in code

  machine from the LCM program and it is then executed

  during the operation of the machine tool 10.

  When the computer numerical control software, including the LCM program 28, is in place, the execution of the digital control software 24 gives rise to repeated calls from the LCM program 28, such as the

  shown in Figure 5. Each resulting pass by the

  LCM gram is called a scan. During each scanning of the LCM program, the fixed LCM routines are executed first to control and control the devices of the machine control station 14. This is followed by the execution of the LCM adaptation routines which define the sequential flow and

  the call of the subprograms of the machine tool.

  The LCM adaptation program 32 may comprise

  a number of sub-program modules, each

  each of them being available for individual adaptation

  Dual. We can increase or decrease the number of modules

  in any particular adaptation, in

  depending on the application considered. Figure 7 shows

  some modules of subroutines that could be arranged in a characteristic way. The invention relates to one of the subprogram modules, namely the LCM 321 display pages. However, for example, the subroutine modules may comprise: a power-up module 322 which includes the routines starting and security interlocks used on the machine during its startup; a Conveyor Module 323 that contains all manual and part program control for transfers; a counter-doll module 324 which controls the counter-doll on the lathe, a Lubrication Module 325 which implements the automatic lubrication of the machine which must be performed or regularly controlled; a sheath module 326 which controls the sheath of the tailstock under the control of the part program; a module of

  Chuck 327 which carries out the control of all the operations

  clamping and unscrewing

  the execution of a part program; a module of

  Tool carrier 328 which controls the tool turret under the control of the part program; a

  Pin Module 329 which controls the speed of the broach

  one turn, and a Cooling Fluid Module 3210 that controls the cooling fluid of the

machine.

  Having thus presented the functional environment, the details of the invention can now be considered. The invention relates to visualization

  graphic information on the cathode ray tube of

  18 of the digital control station 12 which is shown in FIG. 1. The keypad 20 of the digital control station 12 comprises a row of ten keys 66 through which an operator can select a

  any one of ten pages of main visualization

  blades that are frequently used. Each display page consists of a video display of the frame scan type and is generated from view control files stored in memory, not shown, which are part of the digital control software 24. The row of page keys The display 66 is shown in greater detail in FIG. 6. Additional display pages, called subpages, can also be selected.

  means of a set of keys or pushbuttons

  68 are shown in FIG. 1. Four cursor keys are provided to control the up and down and right and left movements of a cursor, for data editing and vertical scrolling. . The right sub-page selections are shown just above the view page key row 66, while the left subpage selections are represented.

  below the row of visual page keys

  and 67 and 69 respectively. The right sub-page selections 67 include, for example: "STATUS OF THE TOOL"; "MACHINE POSITION"; "TOOLING DATA"; etc., while the left 69 subpage selections include "TECH STATUS", "PROGRAM POSITION", etc.

  - Using Adaptation 32 LCM, the software

  sky of CNC system

  offers to the machine tool manufacturer or to the design

  OEM the possibility of defining the format of three

  viewing pages of "machine". We can thus use

  read the adaptation to view any desired machine status information, for assistance from the operator or maintenance personnel. These display pages can be selected by the "MACHINE" key 70 and by the display page options 72 and 74, respectively corresponding to the sub-pages of FIG.

  right and left, in Figure 6.

  Referring now to FIG. 8, it will be noted that when the operator selects one of the three machine visualization pages, the control software

  24 responds to a visualization page procedure

  78 according to the type of page selected, ie the left page, the right page or the main page. The text information, as opposed to the graphic information, is then called from the view control files 80 in which it was previously recorded. The text information, in the appropriate form, is then transmitted to the

  cathode ray tube display device 18.

  When graphics need to be embedded

  in the complete visualization made on the cathodi-

  that, a "call" embedded in the visualization command files 80 triggers the necessary procedures

  to implement the graphic part of the visualization

  tion. The display page routine 78 responds to the graphic display request incorporated in

  triggering a call to the visual page routine

  LCM 32 through a point of entry

  79 of the window 26. A visual change routine

  Graphicalization 82 is executed in response. This rou-

  tine 82 is accessible, for example to a manufacturer of specific equipment adapting a command to a particular machine tool, to achieve adaptation of

  the static part of the graphic display.

  The adaptation is written in PCL, as described above.

  The graphical visualization provided by the rou-

  graphical display change tine 82 is

  static in the sense o once the format and

  visualization were selected, they remain

  remain unchanged until a new

adaptation.

  The visualization change routine

  82 is able to call certain scaling functions

  base entry via entry points 83 in window 26. For example, the routine of

  graphic display change 82 has function

  to: (1) move the slider of the CRT to a particular position on the screen; (2) draw a line between specified points; (3) draw a rectangle, knowing the coordinates of points corresponding to opposite angles; (4) draw an arc of given radius and angle; (5) draw a circle; (60) fill a particular area of the screen; and (7) erase

an area of the screen.

* Three graphical functions are themselves routines of a conventional type that are available on call in the memory of the numerical control system

  by computer, not shown. These functions constitute

  The graphical visualization routines 84 are merged with the text via the files

  respondent is visualized on the cathode tube i8.

  graphically display function data

  in real time. The visual update routine

  Graphic rendering 86 provides virtually in real time these dynamic operating data. In the mode of

  page, the visualization page procedure

  78 performs a periodic call, eg every 150 milliseconds, through the window entry point 81, directed to the graphical display update routine 86. The routine 86 is specially adapted from

  to sample the required information that is

  available by nature in the numerical control system.

  For example, for a tour, it is easy to

  a spindle speed information, in real time.

  This information is simply framed by the graphical display update routine 86 which then triggers one or more of the graphical functions (via the entry points 83), so as to display the information

  proportionally to its real value in real time.

  The visualization update routine

  86 thus functions virtually identically

  than the graphic display change routine 82, except that routine 86 is called from

  repeated and is designed to include

  instantaneous operation. Information

  static and dynamic graphics that are so pro-

  are merged with the text via visualization control files 80 and the display page routine 78 for the presentation

on the cathode ray tube.

  To help understanding the invention,

  a graphical visualization of the type

  which may be desired. By way of example, to create a spindle speed graph for one revolution, expressed as a percentage of the maximum spindle speed, the matching LCM 32 is simply given a configuration capable of creating two contiguous rectangles. , as indicated by reference 88 on cathode ray tube 18 of FIG.

  there is a static part in the visualization of

  seems, the segmented graph that needs to be created is composed essentially of data that are all

  real-time data updated repeatedly

  ve. Because static and dynamic parts are obtained by very similar procedures, it is sufficient

  simply to consider the dynamic part of the information

graphical representation to visualize.

  To create the segmented graph of Figure 8, the display page routine 78 calls all

  the 150 milliseconds the update routine of visualization

  graphical representation 86, via the point of

  81 of the LCM window. The graphic display update routine 86 has real time data about the speed of the lathe spindle, which come from the control system. This information is

  frame and track orders are then issued in accordance

  to the framed information. For example, four orders are necessary: (1) move the cursor to a selected starting point of a first rectangle in the lower left corner thereof; (2) draw the first rectangle up to an end point located in the upper right corner, this point being a function of the actual speed of the spindle; (3) move the cursor again to the starting point of a second rectangle in the lower left corner thereof, so that the second rectangle begins at the point where the first rectangle ends; and (4) then trace the second rectangle to the end point in the upper right corner, this point representing the maximum speed of the spindle. So when the speed of the spindle increases

  or decreases, the two rectangles increase and / or decrease

  shade of length accordingly. The visual aspect is that of a segmented graph representing

the actual speed of the spindle.

  Annex I is a PCL program to create a

  segmented graph as described above.

  Annex II contains routines intended to produce

  window calls to generate the graphs.

  Referring now to Figure 9, there is a flowchart illustrating the functional steps that are implemented in the software to generate graphics on LCM display pages.

  operator requests a particular LCM display page

  operator actuates one of the keys belonging to the keys

  numbers 66 and 68 of the digital control station 12 (FIG.

  1). A test is then performed to determine the existence

  and the availability of a particular page, which is indicated by step 92. Step 93 corresponds to obtaining the following values of the desired parameters

  which must be graphically visualized.

  After determining the visualization page

  sation and parameter values, a call is issued to present the display page, and

  the display page routine 78 is then executed

  as shown in step 96. The initialization part

  The graphical generation is then executed (step 98) and is followed by a periodic update of the graphical display, which is indicated by step 100. During each of the graphical generation steps 98 and 100, there is program calls 82 and 86 issued by the LCM adaptation program 32, to execute seven tracing procedures 102, 104, ... 114,

  with the appropriate parameters, to produce the visualizations

  desired graphics by implementing the seven previously exposed functions such as: moving the graphical cursor to a given position, drawing a rectangle, and so on. A method and system for producing graphical representations has thus been described and shown.

  on a machine tool visualization monitor with
