5-1 Detail of Preparatory Function
1. G-code (Group00)
A. Dwell
1. Command
Setting command G04 in the feed-per-second mode (command G94) delays the start of
execution of the next block for the specified time.
Delay that elapses before the next block
Delay that elapses before the next block
Setting command G04 in the feed-per-revolution mode (command G95) suspends the start
of execution of the next block until the spindle has rotated the specified number of
revolutions.
Number of revolutions to next block
Number of revolutions to next block
B. High-speed machining mode
1. Command
The high-speed machining mode feature allows high-speed execution of programs used
for the machining of free-curved surfaces that have been approximated using very small
lines. In high-speed machining mode, microsegment machining capabilities improve by
several times, compared with conventional capabilities. This allows the same machining
program to be executed at several times the original feed rate, and thus the machining time
to be reduced significantly. Conversely, a machining program that has been approximated
using lines of several fractions of the original segment length, can also be executed at the
same feed rate, so more accurate machining is possible. Combined use of the high-speed
machining mode and the shape correction function allows more accurate machining to be
implemented. If, moreover, a protruding section exists in the microsegment machining
program, smooth interpolation can be conducted automatically by removing this illegal
path.
Absolute data input as well as incremental data input is applicable, indeed, but the former input
mode requires the validation of bit 5 of the F84 parameter.
Type of position data input in the high-speed machining mode
0: Always incremental data input
1: According to the input mode before selection of the high-speed machining mode
