Programming: Multiple Axis Machining
11.2 The PLANE Function: Tilting the Working Plane (Software Option 1)
Dist. tool tip – center of rot. (incremental): The TNC tilts the
tool (or table) relative to the tool tip. The DIST parameter shifts
the center of rotation of the positioning movement relative to
the current position of the tool tip.
Note:
If the tool is already at the given distance to the
workpiece before positioning, then relatively
speaking the tool is at the same position after
positioning (see figure at center right,
If the tool is not at the given distance to the
workpiece before positioning, then relatively
speaking the tool is offset from the original
position after positioning (see figure at bottom
right, 1=DIST).
Feed rate? F=: Contour speed at which the tool should be
positioned
Retraction length in the tool axis?: Retraction path MB is
effective incrementally from the current tool position in the
active tool axis direction that the TNC approaches
tilting. MB MAX positions the tool just before the software limit
switch.
