G33/G95
Default value 840 C-T: 1010 0001
Default value 840 C-M: 1010 0000
Active: In the next block
Bit 7 TRC T: Activation of tool nose radius compensation
M: Activation of cutter radius compensation
Bit 6 Blueprint programming
This function can simplify NC programming. You can enter the words to describe
lines and circles directly from the part drawing. See Programming Guide.
Bit 5 Cycles: This bit activates the reference conditioning (software module), which is
essential for processing stock removal cycle L95.
Bit 3 Extended contour definition programming
This function can simplify NC programming. You can enter the words to describe
lines and circles directly from the drawing into the control. See Programming Guide.
Bit 0 The spindle encoder is taken as a basic measurement for pitch.
