Rotationally symmetric workpiece blank with BLK FORM ROTATION

Application

With BLK FORM ROTATION you define a rotationally symmetric workpiece blank with a definable contour. You define the contour in a subprogram or separate NC program.

Description of function

Blank contour with tool axis Z and main axis X

In the workpiece blank definition you refer to the contour description.

In the contour description, you program a half-section of the contour around the tool axis as the rotational axis.

The following conditions apply to the contour description:

  • Only coordinates of the main axis and tool axis
  • Starting point defined in both axes
  • Closed contour
  • Only positive values in the main axis
  • Positive and negative values are possible in the tool axis

The workpiece preset is in the center of the blank in the working plane. You define the coordinates of the blank contour relative to the workpiece preset. You can also define an oversize.

Syntax element

Meaning

BLK FORM ROTATION

Syntax initiator for rotationally symmetric workpiece blank

Z

Rotary axis

Other possibilities might be available, depending on the machine.

DIM_R or DIM_D

Interpret values in the main axes in the contour description as radius or diameter

LBL or FILE

Name or number of the contour subprogram or path of the separate NC program

Notes

  • If you program the contour description with incremental values, the control interprets the values as radii regardless of whether DIM_R or DIM_D is selected.
  • With the software option CAD Import (#42 / #1-03-1), you can load contours from CAD files and save them in subprograms or separate NC programs.
