Using Hemisphere Milling Cycles
This chapter describes how to use G88.5 and G88.6 to program hemisphere
milling cycles. Use this table to find information:
Information on: On page:
Hemisphere Milling Roughing Cycle (G88.5) 24-1
Concave Hemisphere Roughing Using G88.5 24-2
Convex Hemisphere Roughing Using G88.5 24-5
Hemisphere Milling Finishing Cycle 24-7
Concave Hemisphere Finishing Using G88.6 24-8
Convex Hemisphere Finishing Using G88.6 24-10
Use the G88.5 hemisphere milling roughing cycle to rough out concave or
convex hemispherical pockets.
Important: The active plane is selected using G17, G18, or G19. In this
chapter it is assumed that G17, the XY plane, is selected as the active
plane.
Important: Tool length and diameter offsets must be entered and active
prior to the G88 block.
These features are prohibited during execution of pocket milling cycles:
MDI mode
Tool offset changes through the offset softkey
The following subsections cover using the G88.5 roughing cycle for
concave or convex hemispheres.
