Using Hemisphere Milling Cycles
Chapter 24
24-12
If the programmed Z depth of the pocket has not been reached, another
plunge takes place simultaneously along the X and Z axes to the next L’
level. This plunge simultaneously moves the X and Z axes by the D’ and
L’amounts. This level is then finished as described in the previous
paragraphs. This process is repeated until the programmed Z depth of the
convex pocket is reached, at which time the tool is moved at rapid feedrate
along the Z axis back to the initial Z level. The tool is then moved at rapid
feedrate along the X and Y axes to its pre-cycle position. This completes
the finishing cycle.
Important: The radius of the pocket surrounding the convex hemisphere
is equal t o the radius of the hemisphere plus the tool radius and the finish
allowance.
