Table rotation type machine
- Basic operation
This function is also usable for a table rotation type machine with two table rotation
axes.
The feature coordinate system Xc-Yc-Zc is set in the workpiece coordinate system
based on the coordinate system origin shift (xo, yo, zo) and the Euler's angle.
Given the A-axis and C-axis shown in Fig.3 (l), the A-axis and C-axis rotate until Zc
comes in the X-Z plane and the tool axis is directed toward the +Z-axis direction of
the feature coordinate system.
- Feature coordinate system with the table rotated by G53.1 (tool axis direction control)
The table rotation type machine shown in Fig.3 (l) is explained as an example.
If the table rotates by the tool axis direction control command (G53.1), the feature
coordinate system (called the first feature coordinate system), which is set in the
workpiece coordinate system by the feature coordinate system set command
(G68.2), rotates as much as the table rotates.
The feature coordinate system that has rotated is called the second feature
coordinate system.
Once G53.1 is specified, the subsequent machining commands are assumed to be
specified in the second feature coordinate system. (See Fig.3 (l).)
In the table rotation type machine, the specified feature coordinate system (the first
feature coordinate system) may differ from the feature coordinate system to be used
for machining (the second feature coordinate system).
