294 Cycles: Coordinate Transformations
11.9 WORKING PLANE (Cycle 19, DIN/ISO: G80, Software Option 1)
Automatic positioning of rotary axes
If the rotary axes are positioned automatically in Cycle 19:
îš„ The TNC can position only controlled axes
îš„ In order for the tilted axes to be positioned, you must enter a feed
rate and a setup clearance in addition to the tilting angles, during
cycle definition.
îš„ Use only preset tools (the full tool length must be defined).
îš„ The position of the tool tip as referenced to the workpiece surface
remains nearly unchanged after tilting.
îš„ The TNC performs the tilt at the last programmed feed rate. The
maximum feed rate that can be reached depends on the complexity
of the swivel head or tilting table.
Example NC blocks:
10 L Z+100 R0 FMAX
11 L X+25 Y+10 R0 FMAX
12 CYCL DEF 19.0 WORKING PLANE
Define the angle for calculation of the compensation
13 CYCL DEF 19.1 A+0 B+45 C+0 F5000 SETUP50
Also define the feed rate and the clearance
14 L Z+80 R0 FMAX
Activate compensation for the spindle axis
15 L X-8.5 Y-10 R0 FMAX
Activate compensation for the working plane
