HEIDENHAIN CNC PILOT 4290 591
7.6 Machining Parameters
4 – Roughing
Roughing – Tool standards
Furthermore:
 Roughing cycles are primarily executed with standard roughing
tools.
 Alternatively, tools that allow full-surface machining are used.
Roughing – Machining standards
To ol st a n d ard s
 Tool angle – external/longitudinal [RALEW]

Input for RAL, RIL, RAP, RIP:
 0: Full-surface roughing cycle, including plunge-cutting.
TURN PLUS looks for a tool for full-surface machining.
 1: Standard roughing cycle without plunge-cutting
