Background technique

The TL life of the Fanuc system is the sister tool system that comes with the system, which can group several tools into one group, and manage the life of the tools on the turret according to the group. The lathe probe is a device that can record the current position of each axis of motion. , to measure the size of the workpiece and adjust the tool compensation. In the actual lathe production and processing process, the unit carries a variety of tools, and at the same time, a variety of tools are equipped with spare tools, so the number of tools is large. During the process, because the tool position number and tool compensation position number are constantly changing when using the TL life, the system cannot identify the number of times of use and wear of the tool in the tool group, and the precision of the processed parts is not enough, and the on-site staff needs to manually After multiple compensations and calibrations, it is impossible to update and calibrate the machining tool in real time.

The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only It is an embodiment of a part of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having", as well as any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or device comprising a sequence of steps or elements is not necessarily limited to the expressly listed instead, may include other steps or elements not explicitly listed or inherent to the process, method, product or apparatus.

The present invention provides an automatic tool change and compensation processing method, as shown in Figure 1, comprising the following steps:

S1: Number multiple tools in the machine, record the number of times the tool is used, and form a dynamic combination number; specifically, the multiple tools in the machine include multiple tools of different types, and set multiple tools of the same type as one tool Group;

S2: The measured value of the processed part size is measured by the stylus. If it does not meet the preset value, the tool length compensation is performed, and the length compensation information is updated to the corresponding tool calibration system based on the dynamic combination number information, and the machining is performed again. Components;

S3: If the size of the processed part meets the preset value, the service life of the corresponding tool is judged based on the combination number, and if it exceeds the service life threshold, it is replaced, otherwise the tool continues to process the next part.

Preferably, the calculation of tool usage times in this application is based on the TL life system for identification and counting, and the detection of processed parts is based on the side head system. In this application, the length compensation information is updated to the corresponding tool calibration system based on the dynamic combination number information The programming method in is:

#[2000+#4120/101]＝#[2000+#4120/101]+#515*#800

Among them, #515 is the difference between the measured value and the workpiece center difference, #800 is the correction coefficient; #4120 is the T code information of the current tool, that is, the dynamic combination number, if the current tool is T0808, the output value of #4120 is 808, so #4120/101 is the serial number 8 of the current tool compensation, and #2001 to #2064 in the system respectively represent 1 to 64 bits to the tool X-axis wear compensation, so the above tool compensation program can be added to the tool compensation value and superimposed on the Write the new tool wear compensation into the system on the original tool correction number; since the tool number and tool compensation number are always changing when the TL life is used, it can ensure that no matter which tool is used in the TL life Add the tool compensation value to the correct tool compensation number.

Preferably, as shown in Figure 2, the dynamic combination number in the step S1 includes the knife group number, the specific number of the tool in the knife group, and the number of accumulated or decremented use times; further, the step S1 is preferably used Tools with fewer usage times; further, in the step S1, based on the processing amount and material of the product to be processed, and the tool wear coefficient, the threshold value of the number of times of use is preset for all tools. For the wear coefficient of the tool, those skilled in the art based on long-term processing Accumulated experience can be obtained;

Specifically, use the CNC program to input the tool information into the system and define the tool life. The input procedure is as follows:

O1002

G10L03 (Enable programmable data input, input data to TL life, delete all groups when logging in)

P01L100 (Log in to the first group, the life is 100, you can select the processing times or working hours in the TL life interface to define the life threshold, in this application, it is the tool processing times)

T0101

T0202

T0303

G11 (close programmable data input)

M30

There are three preset system tools, and their dynamic combination numbers are T0101, T0202, and T0303. Using this program, T0101, T0202, and T0303 can be entered into a group, and the life of each tool in the group is preset to 100; You can use T0199 to call this group of tools during actual processing. When calling, the tools will be called according to the number of times processed before. T0101 is used first for processing. If the number of processing cycles is greater than 100 but less than 200, call T0202, and when it is greater than 200 but less than 300, call T0303. If it is greater than 300, the machine tool will alarm and stop the cycle. At this time, the worker will change the three tools and clear the processing count in the TL life, and then continue to start, thus realizing a cycle.

Preferably, as shown in FIG. 3 , updating the length compensation information to the corresponding tool calibration system based on the dynamic combination number information in the step S2 includes the following steps: calculating the difference between the measured value of the processed part size and the preset value, The correction coefficient is obtained according to the use times in the dynamic combination number information; the product of the difference value and the correction coefficient is used as the wear compensation value of the tool.

Preferably, the failure to meet the preset value in the step S2 includes two situations. If the measured value of the part size after processing is greater than the upper difference of the part, the length compensation is performed on the tool, and the length compensation information is updated based on the dynamic combination number information to In the corresponding tool calibration system, the parts are processed again;

If the measured value of the part size after processing is smaller than the part drop, the part will be scrapped and an early warning will be given.

Preferably, in the step S3, it is judged whether the service life threshold is exceeded based on the number of times of use in the dynamic combination number. If there is no need to replace a new tool, proceed to the next step. If a new tool needs to be replaced, and there is no spare tool in the same group of tools A warning is issued.
