10757 Channel %1 block %2 changing the compensation plane while tool

radius compensation is active not possible

Parameters: %1 = channel number

%2 = block number, label

Definitions: In order to change the compensation plane (G17, G18 or G19) it is first necessary to deselect the cut-

ter radius compensation with G40.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Insert an intermediate block in the part program using the correction deselection. After the plane

change, the cutter radius compensation is to be selected in an approach block with linear interpolation.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10758 Channel %1 block %2 curvature radius with variable compensation value

too small

Parameters: %1 = channel number

%2 = block number, label

Definitions: The current cutter radius compensation (the cutter used) is too large for the programmed path radius.

In a block with variable tool radius compensation, a compensation must be possible either anywhere

or nowhere on the contour with the smallest and the largest compensation value from the programmed

range. There must be no point on the contour in which the curvature radius is within the variable com-

pensation range.

If the compensation value varies its sign within a block, both sides of the contour are checked, other-

wise only the compensation side.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Use smaller cutters or allow for a part of the cutter radius at the time of contour programming.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10759 Channel %1 block %2 path is parallel to tool orientation

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: In a block with spline or polynomial interpolation, the corrected path runs in at least one point parallel

to the tool orientation, i.e. the path has a tangent perpendicular to the compensation plane.

Straight lines running parallel to the tool orientation are permissible, as well as circles, with a circle

plane that is perpendicular to the compensation plane (application in smooth retraction from a groove).

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Do not use splines or polynomials when writing the contour section, but straight lines and circles

instead. Divide up the tool piece geometry and deselect the cutter radius compensation between the

various sections.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.
