13.FUNCTIONS TO SIMPLIFY PROGRAMMING PROGRAMMING B-63324EN/03

by resetting the CNC by the input of the ERS, ESP, or RRW signal
from the PMC.
Even if bit 4 (D3R) of parameter No. 6400 is set to 1,
G69 mode is assumed when program execution is
- Custom macro system variable
If the workpiece coordinates of the tool currently being used are read
using custom macro system variables #5041 to #5050 (ABSOT), the
coordinates in the program coordinate system before coordinate
conversion can be read even in three-dimensional coordinate
conversion mode (G68). When bit 5 (D3M) of parameter No. 6400 is
set to 1, the coordinates in the workpiece coordinate system after
coordinate conversion can be read.
- Rapid traverse rate for hole machining in a canned cycle
In three-dimensional coordinate conversion mode, rapid traverse for
hole machining in a canned cycle is performed using the cutting
feedrate specified in parameter No. 2052. When this parameter is set to
0, the maximum cutting feedrate is used.
- Compensation functions
If tool length compensation, cutter compensation, or tool offset is
specified with three-dimensional coordinate conversion, compensation
is performed first, followed by three-dimensional coordinate
- Relationship between three-dimensional and two-dimensional coordinate
conversion (G68, G69)
Three-dimensional and two-dimensional coordinate conversion use
identical G codes (G68 and G69). A G code specified with I, J, and K is
processed as the command for three-dimensional coordinate
conversion. A G code not specified with I, J, and K is processed as the
command for two-dimensional coordinate conversion.
- Manual operation
In three-dimensional coordinate conversion mode (G68), the following
two types of manual operation (jog feed, manual incremental feed, and
manual handle feed) are supported:
(1) Operation in a workpiece coordinate system (with three-
dimensional coordinate conversion not applied)
(2) Operation in a program coordinate system (with three-
dimensional coordinate conversion applied)
For information about which type is used, refer to the manual provided
by the machine tool builder.
