By contrast, when the movement range is set to 0 to 360 degrees, the output angles
are (A θ2 degrees; B φ2 degrees). Neither rotation axis A nor B moves in a way that
it exceeds 0 degree (360 degrees).
Operation examples
- In the case of a tool rotation type machine
Explanations are given below assuming a machine configuration in which a tool
rotation axis that turns around the Y-axis is located beneath another tool rotation axis
that turns around the Z-axis. (See Fig.4 (j).)
If linear interpolation is specified for the X-, Y-, and Z-axes when a workpiece
coordinate system is used as the programming coordinate system, control is exerted
in such a way that the tool center point moves along a specified straight line with
respect to the table (workpiece) as the tool rotates.
Also, speed control is exerted so that the tool center point moves at the specified
speed with respect to the table (workpiece).
In the case of a machine having two tool rotation axes, the table does not rotate with
respect to the workpiece coordinate system even if the rotation axes move.
Therefore, the programming coordinate system always matches the workpiece
coordinate system,regardless of whether parameter WKP(No.19696#5) is set to 0 or
1.
Examples)
For type 1:
O100 (Sample Program1) ;
N1 G00 G90 B0 C0 ;
N2 G55 ; Prepares the programming coordinate
system.
N3 G43.4 H01 ; Starts tool center point control.
H01 is the tool compensation number.
N4 G00 X200.0 Y150.0 Z20.0 ; Moves to the start point.
N5 G01 X5.0 Y5.0 Z5.0 C60.0 B45.0 F500 ; Linear interpolation
N6 G49; Cancels tool center point control.
