CONTOUR DATA (Cycle 20)
Cycle 20 CONTOUR DATA defines the machining information for cycles 21
to 24.
8 CYCL DEF: Select Cycle 20 CONTOUR DATA
8 Milling depth: Distance between workpiece surface and bottom of
pocket: Q1
8 Path overlap factor: Q2
8 Finishing allowance for side: Q3
8 Finishing allowance for floor: Q4
8 Workpiece surface coordinate: Coordinate of the workpiece surface
referenced to the current datum: Q5
8 Set-up clearance: Distance from the tool to the workpiece surface: Q6
8 Clearance height: Height at which collision with the workpiece is
impossible: Q7
8 Inside corner radius: Rounding radius at inside corners referenced to
the tool midpoint path: Q8
8 Direction of rotation: Q9: Clockwise Q9 = –1; counterclockwise
Q9 = +1
