Using Hemisphere Milling Cycles
This chapter describes how to use G88.5 and G88.6 to program hemisphere
milling cycles. Use t his table to find information:

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 e ntered and active
prior t o the G88 block.
These features are prohibited during execution of pocket milling cycles:

The following subsections cover using the G88.5 roughing cycle for
concave or convex hemispheres.
