8.2 Parameters
Descriptions of the most important machining
parameters (processing)
General settings
Global technology parameters – Safety clearances
Machining parameters are used by the work plan
generation (TURN PLUS) and various machining cycles.
Global safety clearance
Speed limiting [SMAX]
Global speed limiting. You can define a small speed limit in the
program head of the TURN PLUS program.
 External on blank part [SAR]
 Internal on blank part [SIR]
TURN PLUS takes SAR/SIR into account
 for all rough-turning operations
 for centric predrilling
 External on machined part [SAT]
 Internal on machined part [SIT]
TURN PLUS takes SAT/SIT into account on premachined
workpieces for:
 Finish-machining
 Recess turning
 Contour recessing (contour cutting)
 Recessing
 Thread cutting
 Measuring
G14 for new units
Default setting for the axis sequence (start unit: GWW parameter)
that is used to approach the tool change position:
 No axis
 0: Simultaneously
 1: First X, then Z
 2: First Z, then X
 3: Only X
 4: Only Z
