Driving gear and turbine components
Example finishing The subprogram contains the NC blocks for the geometry and all the data required for produc-
subprogram: FINISH_04 tion. Assuming that your post processor has been optimized, all this data should be listed in the
subprogram. All subprograms are structured in a similar fashion. They only differ in terms of the
tool data, technology data, CYCLE832 parameters, and of course the NC blocks.

; Tool specification in the form of a comment
; Dimensions of the cherry tool 8 mm
; Tolerance specification in the form of a comment
; Tool radius compensation, working plane, metric sys-
; tem, feedrate in mm/min in relation to spindle, absolute
dimension specification
; Deactivate all active transformations and frames
; Swivel all axes to the normal position
; Resetting of the swiveled planes for defined original
; position
; Call tool T1
; Change tool in spindle
; Work offset
; Workpiece coordinate system is valid
; Axis interpolation
; Spindle speed, clockwise rotation, cooling on
; Pre-positioning of the tool in relation to the workpiece. In
; each subprogram, a fixed position should first be
; approached/swiveled into so that there is a defined orig-
; inal position at the start of machining. This means that if
; TRAORI is active, the way the workpiece is approached
; may vary under certain circumstances. Pre-positioning
without TRAORI.
; Define high speed settings, 0.01 tolerance. From right to
; left: 1 finishing activated, 0 not assigned, 0 TRAORI
; deactivated, 2 G642, 1 FFWON SOFT, 1 COMPCAD.
; Activate TRAORI
; Reactivate work offset after TRAORI
; Rapid traverse to position, define spindle speed and
; direction of rotation
; Approach first position with feedrate, coolant on
; NC blocks for geometry
; Retraction in Z
; Deactivate transformation
; Set CYCLE832 to default values
; Resetting of the swiveled planes
; Spindle stop
; End of subprogram
