U Angle of face Q496: Angle between the face 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
(radius value) in radial 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.
U Oversize in diameter Q483: Diameter oversize for
the defined contour
U Oversize in Z Q484: Oversize for the defined contour
in axial direction
U Finishing feed rate Q505: Feed rate during
finishing. If M136 has been programmed, the value is
interpreted by the TNC in millimeters per revolution,
without M136 in millimeters per minute.
