Cutting distance

TC_SHEET_THICK

Definition

Defines the Z position of the upper side of the sheet. Is used when cutting without active height regulation in order to define the position of the cutting head.

The theoretical Z position of the upper side of the sheet is assumed when work is done without TC_SHEET_THICK.

The measured Z position is taken into account for the next TC_LASER_ON call with the laser methods 2, 3, 6, 8, 10 and 12. The position of the laser cutting head is calculated by adding the measured value of TC_SHEET_THICK and of the nozzle distance from the technology table.

Programming

TC_SHEET_THICK:

Single-head mode must be selected in the laser cutting head table. Otherwise an error message will appear.
Is always called up with a program-specific laser technology table.
Takes effect with the next TC_LASER_ON call, which is programmed with one of the laser methods 2, 3, 4, 6, 8, 10 and 12.
Acts till the next TC_LASER_OFF call.
Deleted by M30 and RESET.

Application

Machining of blanks.
Separation of waste grids.
