11.5 Four Axis Programming
Rotary Axis Programming Conventions
A rotary axis (typically U) programs differently based on the setting
of the (Axes->PhysicalAxis->U->CfgRollOver>Shortest Distance)
parameter, which is determined by the builder. The default for this
parameter is off; in which case, the U-axis behaves like a linear axis.
If set to on, the behavior of the rotary axis (U) is described below.
If programming the U-axis in Absolute:
The rotary axis never rotates more than 180 degrees in one move.
So, if a move of greater than 180 degrees is programmed, the
control resolves the number to a positive value less than 360
degrees and move to that target, taking the shortest distance
(always less than 180 degrees). A move of exactly 180 degrees
always moves positive and a move of exactly 360 degrees does not
move at all.
If programming the U-axis in Incremental:
The rotary axis moves the exact amount of degrees programmed
and in the direction indicated with the plus or minus sign. The
display resets to zero every time 360 degrees is crossed so that the
highest value in the U-axis display is 359.999 degrees depending on
the displayed resolution.
Feedrate display is always vectored.
Programming Examples
All programming examples are for 4-axis machining with the rotary
table mounted on the left end of the mill table, with the center line
of the rotary axis parallel to the X-axis. The face of the rotary table
faces X+.
The examples contain both milling and drilling applications. Modal
cycles G81 to G89 and G66 can be executed at rotary locations as in
XYZ locations. Non-modal canned cycles can be executed at rotary
locations. Position the rotary axis before you execute a non-modal
canned cycle.
