Cycle parameters

Q215 Machining operation (0/1/2/3)?: Define
machining operation:
0: Roughing and finishing
1: Only roughing
2: Only finishing to finished dimension
3: Only finishing to oversize
Q460 Set-up clearance?: Reserved, currently
without function
Q491 Diameter at contour start?: X coordinate of
the contour starting point (diameter value)
Q492 Contour start in Z?: Z coordinate of the
contour starting point
Q493 Diameter at end of contour?: X coordinate
of the contour end point (diameter value)
Q493 Contour end in Z?: Z coordinate of the
contour end point
Q495 Angle of side?: Angle between the side at
the contour starting point and the perpendicular to
the rotary axis
Q501 Starting element type (0/1/2)?: Define
the type of element at the start of the contour
(circumferential surface):
0: No additional element
1: Element is a chamfer
2: Element is a radius
Q502 Size of starting element?: Size of the
starting element (chamfer section)
Q500 Radius of the contour corner?: Radius of
the contour inside corner. If no radius is specified,
the radius of the cutting insert is generated.
Q496 Angle of second side?: Angle between
the side at the contour end point and the
perpendicular to the rotary axis
Q503 End element type (0/1/2)?: Define the type
of element at the end of the contour:
0: No additional element
