Machining Cycles

Cedpfx Ajyxw Ddel Njrh
Standard software options: Conversational programming, 38 reference point shifts, rotation and mirroring, teach-in for X, Y, Z, program restart with selectable entry functions
Zero point determination: cycles for determining reference points by manual probing of the workpiece for:
- Arbitrary clamped rectangular parts
- Arbitrary clamped round parts
- Centering of cast and flame-cut parts
- Angle position detection for round parts by probing reference edges or surfaces
Test graphics: Graphical display of drilling patterns
