Milling a circular spigot - CYCLE77
Programming
CYCLE77 (RTP, RFP, SDIS, DP, DPR, PRAD, PA, PO, MID, FAL, FALD, FFP1, FFD, CDIR, VARI, AP1)
Parameters
The following input parameters are always required:
Parameter
Data type
Description
RTP REAL Retraction plane (absolute)
RFP REAL Reference plane (absolute)
SDIS REAL Safety clearance (enter without sign)
DP REAL Depth (absolute)
DPR REAL Depth relative to the reference plane (enter without sign)
PRAD REAL Spigot diameter (enter without sign)
PA REAL Center point of spigot, abscissa (absolute)
PO REAL Center point of spigot, ordinate (absolute)
MID REAL Maximum depth infeed (incremental; enter without sign)
FAL REAL Final machining allowance at the margin contour (incremental)
FALD REAL Finishing allowance at the base (incremental, enter without sign)
FFP1 REAL Feedrate on contour
FFD REAL Feedrate for depth infeed (or spatial infeed)
CDIR INT Milling direction (enter without sign)
Values:
0: Down-cut milling
1: Conventional milling
2: With G2 (independent of spindle direction)
3: With G3
VARI INT Machining type
Values:
1: Roughing to final machining allowance
2: Finishing (allowance X/Y/Z=0)
AP1 REAL Length of blank spigot
Function
Use this cycle to machine circular spigots in the machining plane. For finishing, a face cutter is required. The depth infeed is
always performed in the position before the semi-circular approach to the contour.
