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
contour starting point (diameter value)
U Contour start in Z Q492: Z coordinate of the contour
starting point (diameter value)
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 face Q495: Angle between the face and the
rotary axis
U Starting element type Q501: Define the type of the
element at the contour start (circumferential surface):
0: No additional element
1: Element is a chamfer
2: Element is a radius
U Size of starting element Q502: Size of the starting
element (chamfer section)
U Radius of contour edge Q500: Radius of the inside
contour edge. If no radius is specified, the radius of
the cutting insert is generated.
U Angle of circumferential surface Q496: Angle
between the circumferential surface and the rotary
axis
U Type of end element Q503: Define the type of the
element at the contour end (face):
0: No additional element
1: Element is a chamfer
2: Element is a radius
U Size of end element Q504: Size of the end element
(chamfer section)
U Maximum cutting depth Q463: Maximum infeed in
axial direction. The infeed is divided evenly to avoid
abrasive cuts.
