Define the blank: BLK FORM
Immediately after initiating a new program, you define a cuboid,
unmachined workpiece blank. If you wish to define the blank at a
later stage, press the
spec fct
key, the PROGRAM DEFAULTS soft
key, and then the
BLK FORM
soft key. The TNC needs this definition
for graphic simulation.
You only need to define the workpiece blank if you
wish to run a graphic test for the program!
The TNC can depict various types of blank forms.
Soft key
Function
Define a workpiece blank
Define a cylindrical blank
Define a rotationally symmetric blank
Rectangular blank
The sides of the cuboid lie parallel to the X, Y and Z axes. This
blank is defined by two of its corner points:
MIN point: the smallest X, Y and Z coordinates of the blank
form, entered as absolute values
MAX point: the largest X, Y and Z coordinates of the blank form,
entered as absolute or incremental values
Example: Display the BLK FORM in the NC program
0 BEGIN PGM NEW MM
Program begin, name, unit of measure
1 BLK FORM 0.1 Z X+0 Y+0 Z-40
Spindle axis, MIN point coordinates
2 BLK FORM 0.2 X+100 Y+100 Z+0
MAX point coordinates
3 END PGM NEW MM
Program end, name, unit of measure
