Cycle parameters
U Machining operation Q215: Define the machining
operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing to finished dimension
3: Only finishing to oversize
U Set-up clearance Q460 (incremental): Distance for
retraction and pre-positioning
U Diameter at contour start Q491: X coordinate of the
starting point for the plunging path (diameter value)
U Contour start in Z Q492: Z coordinate of the starting
point for the plunging path
U Diameter at end of contour Q493: X coordinate of
the contour end point (diameter value)
U Contour end in Z Q494: Z coordinate of the contour
end point
U Angle of side Q495: Angle of the plunging side. The
reference angle is formed by the parallel line to the
rotary axis.
U Maximum cutting depth Q463: Maximum infeed in
axial direction. The infeed is divided evenly to avoid
abrasive cuts.
U Roughing feed rate Q478: Feed rate during roughing.
If M136 has been programmed, the value is
interpreted by the TNC in millimeters per revolution,
without M136 in millimeters per minute.
