- In the case of a table rotation type machine
Explanations are given below assuming a machine configuration (trunnion) in which a
rotation table that turns around the Y-axis is located above another table rotation axis
that turns around the X-axis. (See Fig.4 (k).)
If linear interpolation is specified for the X-, Y-, and Z-axes on the programming
coordinate system and if the rotation axis that moves the rotation table is specified
(in the case of type 1) or the tool direction is specified (in the case of type 2), 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 rotation table rotates.
Also, speed control is exerted so that the tool center point moves at the specified
speed with respect to the table (workpiece).
Example)
When type 1 is selected and the coordinate system fixed on the table is used as the
programming coordinate system
(Parameter WKP (No.19696#5) = 0):
O200 (Sample Program2) ;
N1 G00 G90 A0 B0 ;
N2 G55 ; Prepares the programming coordinate
system.
N3 G43.4 H01 ; Starts tool center point control.
H01 is the tool compensation number.
N4 G00 X20.0 Y100.0 Z0 ; Moves to the start point.
N5 G01 X10.0 Y20.0 Z30.0 A60.0 B45.0 F500 ; Linear interpolation
N6 G49; Cancels tool center point control.
