Journey.
S110, measured workpiece is placed on transparent display platform.Measured workpiece is placed in transparent display platform,
From being carried out in this way to measured workpiece from the positive and negative both sides of transparent display platform and absorb bidimensional image.
S120, the two-dimentional drawing that measured workpiece is shown on the transparent display platform.Using computer, output is simultaneously
The two-dimentional drawing of measured workpiece is shown in transparent display platform.Two-dimentional drawing is CAD diagram paper, can also be the figure of extended formatting
Paper, such as photo.CAD diagram paper is in transparent display platform with 1：The actual size of the two-dimensional silhouette of 1 display measured workpiece.
S130, keep two-dimentional drawing Chong Die with the material object of measured workpiece.
In this step, keep the two-dimentional drawing shown on transparent display platform Chong Die with the material object of measured workpiece.Specifically

Picture and the overlapping figure of two-dimentional drawing；Can also be：The overlapping figure directly output is printed upon on drawing.
It is S160, whether qualified according to the diversity judgement measured workpiece of the bidimensional image of measured workpiece and two-dimentional drawing.Overlapping
, can be by manually judging the difference of bidimensional image and two-dimentional drawing after figure is shown, and then judge whether measured workpiece is advising
In lattice.Artificial judgement is suitble to all workpiece, is particularly suitable for simple overall size.
It is different from traditional scheme, in this step, do not need to calculate the bidimensional image of the measured workpiece of acquisition.Sentence
Whether disconnected measured workpiece is that the bidimensional image directly by measured workpiece is compared with two-dimentional drawing in specification.Therefore, shorten
It the judgement qualified time, improves work efficiency.
Wherein, for the tool of simple overall size shape, drawing comparison is directly carried out, artificial judgement can be rapidly and accurately
Judge whether qualification, naturally it is also possible to be compared by software.For the complex-shaped tool of overall size, except artificial contrast it
Outside, the step of can also being compared by software, being calculated due to the bidimensional image for saving to measured workpiece, therefore, it is determined that being
No qualification is quick and precisely.That is, in this step, either artificial contrast's judgement or software comparison all need not be to obtaining
The bidimensional image of the measured workpiece taken is calculated.
The difference value of the bidimensional image of S170, calculating and output measured workpiece and two-dimentional drawing.
In previous step S160, it would know that measured workpiece whether within specification, can meet most demand.But
In some cases, it may be necessary to the specific difference value between underproof measured workpiece and standard is known, in favor of subsequently improving.
Therefore, it in this step, is handled and is calculated using software image, the difference value between measured workpiece and drawing can be obtained.The difference
Different value may be displayed on display screen.It can also be printed upon on drawing simultaneously in the drawing of output overlapping figure.If no
Need to know the specific difference value between measured workpiece and standard size, then this step can be omitted.
