Cycle 1281 OCM RECTANGLE BOUNDARY (#167 / #1-02-1)

ISO programming

G1281

Application

Use Cycle 1281 OCM RECTANGLE BOUNDARY to program a rectangular bounding frame. This cycle can be used to define the outer boundary of an island or a boundary of an open pocket that was programmed before by using the respective OCM standard figure.

Notes

  • This cycle can only be executed in the FUNCTION MODE MILL machining mode.
  • Cycle 1281 is DEF-active, which means that it becomes active as soon as it is defined in the NC program.
  • The boundary data entered in Cycle 1281 are valid for Cycles 1271 to 1274 and 1278.

Parameter

Q651 Length of major axis?

Length of the first side of the boundary, parallel to the main axis. This value has an incremental effect.

Input: 0.001...9999.999

Q652 Length of minor axis?

Length of the second side of the boundary, parallel to the secondary axis. This value has an incremental effect.

Input: 0.001...9999.999

Q654 Position reference for figure?

Specify the position reference for the center:

0: The center of the boundary is referenced to the center of the contour

1: The center of the boundary is referenced to the datum

Input: 0, 1

Q655 Shift in major axis?

Shift of the rectangle boundary along the main axis

Input: -999.999...+999.999

Q656 Shift in minor axis?

Shift of the rectangle boundary along the secondary axis

Input: -999.999...+999.999
