Dist. tool tip - center of rot. (incremental): The DIST parameter
shifts the center of rotation of the tilting movement relative to the
current position of the tool tip.
If the tool is already at the specified distance from the
workpiece prior to being tilted into position, then it will be at
the same relative position after being tilted into position (see
center figure on the right,
If the tool is not at the specified distance from the workpiece
before being tilted into position, then it will be offset relative to
the original position after being tilted into position (see lower
figure on the right,
The control tilts the tool (or table) relative to the tool tip.
Feed rate? F=: Contour speed at which the tool is to be tilted into
position
Retraction length in the tool axis?: The retraction path MB
takes effect incrementally from the current tool position in the
active tool axis direction that the control approaches before
tilting. MB MAX moves the tool to a position just before the
software limit switch
