3 Description
- When a coordinate system fixed on the table is used as the programming coordinate system
The programming coordinate system is used for tool center point control.
When the G43.4 or G43.5 command is specified with parameter WKP (No.19696#5)
set to 0, the workpiece coordinate system that is fixed on the table at that point of time
becomes the programming coordinate system.
Thereafter, the programming coordinate system rotates as the table turns around.
It does not rotate with the tool head rotating.
X, Y, and Z mentioned hereinafter are assumed to be commanded on the
programming coordinate system.
When the rotation axis of the table has moved in a block preceding G43.4 or G43.5 or
at the block of G43.4 or G43.5, the angle of the table's rotation axis at the end of
G43.4 or G43.5 block represents the initial state of the programming coordinate
system.
In the case of type 2, the tool direction seen from the coordinate system that is fixed
on the table is specified by I, J, K.
In the descriptions that follow, the table-fixed coordinate system is represented by X',
Y', and Z'.
