Programming: Multi-Axis Machining
12.2 The PLANE function: Tilting the working plane (software option 8)
If you use PLANE together with STAY, you have to
position the rotary axes in a separate block after the
PLANE function.
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 in center right,
If the tool is not at the given distance from the
workpiece before tilting, then relatively speaking
the tool is offset from the original position after
tilting (see figure in 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.
