Cylindrical blank
The cylindrical blank form is defined by the dimensions of the
cylinder:
R: Radius of the cylinder
L: Length of the cylinder
DIST: Distance from datum to cylinder end
RI: Inside radius for a hollow cylinder
The DIST and RI parameters are optional and do not
need to be programmed.
Example: Display the BLK FORM CYLINDER in the NC program
0 BEGIN PGM NEW MM Program begin, name, unit of measure
1 BLK FORM CYLINDER Z R50 L105 DIST+5 RI10 Spindle axis, radius, length, distance, inside radius
2 END PGM NEW MM Program end, name, unit of measure
Rotationally symmetric blank of any shape
You define the contour of the rotationally symmetric blank in a
subprogram. In the workpiece blank definition you refer to the
contour description:
DIM_D, DIM_R: Diameter or radius of the rotationally
symmetrical blank form
LBL: Subprogram with the contour description
The subprogram can be designated with a number,
an alphanumeric name, or a QS parameter.
Example: Display the BLK FORM ROTATION in the NC program
0 BEGIN PGM NEW MM Program begin, name, unit of measure
1 BLK FORM ROTATION Z DIM_R LBL1 Spindle axis, manner of interpretation, subprogram number
