Work platformses based on workbench, implementation is as described below：
A modification source processed file) is needed, a new file to be processed is generated according to the source processed file of loading, this is newly treated
In processed file, containing the cutter track information in the information of taking pictures, source processed file, wherein, the fundamental mesh of a new file to be processed
Formula is：
Auxiliary working platform returns Workpiece zero point；
It is switched to exposal model；
Major-minor workbench unit one is taken pictures；
Major-minor workbench second workpiece is taken pictures；
Take pictures end notification；
Auxiliary working platform corrects the position of unit one；
Checking auxiliary working platform correction result (a workpiece is taken pictures, the difference of etection theory position and physical location
Whether in the range of error of setting, if the difference exceeds range of error, order Digit Control Machine Tool stops processing, otherwise continues to add
Work)；
It is switched to cooked mode；
Cutter track in the processed file of source；
B) new file to be processed is parsed and is performed, detailed step is as follows：
A () auxiliary working platform returns Workpiece zero point, it is ensured that the workpiece that auxiliary working platform is recorded when taken pictures with main workbench simultaneously is theoretical
Position is accurate；

Two Z axis go to first count simultaneously according to point position, and the workpiece 1 to placing on main workbench is taken pictures, when taking pictures
Record is taken pictures the theoretical position of a little corresponding workpiece 1, takes pictures after terminating, using image identification function, calculates the reality of workpiece 1
Position, and the physical location is recorded, then, two main shafts go to second count simultaneously according to point position, to what is placed on auxiliary working platform
Workpiece 2 is taken pictures, same to record theoretical position and physical location.
D () has two groups of theoretical positions and physical location, it is possible to which the workpiece opposite piece calculated on major-minor workbench is former
The rotational offset of point, detailed calculating process are as follows：
A. calculate the rotational offset of auxiliary working platform：With two physical locations of main workbench record as reference, and secondary work
Two actual calculation of location for making platform record go out an anglec of rotation and skew, remember that the anglec of rotation and the matrix for offseting are A, make
Obtain auxiliary working platform to rotate and offset through this angle, can reach as the workpiece coordinate of main workbench workpiece physical location.
B. calculate the rotational offset of main workbench：With two physical locations of main workbench record as reference, and main work
Two theoretical positions for making platform record calculate an anglec of rotation and skew, remember that the anglec of rotation and the matrix for offseting are B, make
The relatively main workbench of auxiliary working platform it is static after, as main workbench is rotated and offset through this angle, major-minor work can be realized
The purpose that bench work's part is all corrected.
If e () also has other workpiece, then take pictures to other workpiece of major-minor workbench, process of taking pictures is with above-mentioned step
Suddenly, by that analogy, after all workpiece have all taken photograph, send end notification of taking pictures.
C workpiece 1 and workpiece 2 are processed)：
Auxiliary working platform is moved, and using matrix A, corrects the workpiece seat of the workpiece 2 on auxiliary working platform and workpiece 1 on main workbench
Mark is identical, and the processor command ccd image sensor of Digit Control Machine Tool is taken pictures to workpiece 1 and proof theory position and actual bit again
Whether the difference put exceeds range of error, if exceeding, order Digit Control Machine Tool stops processing, is otherwise switched to cooked mode, secondary
The relatively main workbench of workbench is static, and auxiliary working platform uses matrix B with main workbench, corrects and process workpiece 1 and 2 together.
D) after workpiece 1 and 2 process finishings, the workpiece processed is needed below according to above-mentioned steps A) to C) perform, until
All of workpiece all high efficiency, high-precision process finishing.
