Input data
• MILLING DEPTH Q1:
Distance between the cylindrical surface and the floor of the contour.
• ALLOWANCE FOR SIDE Q3:
Finishing allowance in the plane of the unrolled cylindrical surface.
This allowance is effective in the direction of the radius compensation.
• SETUP CLEARANCE Q6:
Distance between the tool tip and the cylinder surface.
• PECKING DEPTH Q10:
Dimension by which the tool advances in each infeed.
• FEED RATE FOR PECKING Q11:
Feed rate for traversing in the tool axis.
• FEED RATE FOR MILLING Q12:
Feed rate for traversing in the working plane.
• RADIUS Q16:
Radius of the cylinder on which the contour is to be machined.
• DIMENSION TYPE (ANG/LIN) Q17:
The dimensions for the rotary axis of the subprogram are given either
in degrees (0) or in mm/inch (1).
Prerequisites
• The cycle requires a center-cut end mill (ISO 1641).
• The cylinder must be set up centered on the rotary table.
• The tool axis must be perpendicular to the rotary table axis. If this is
not the case, an error message will result.
