8 Deceleration Check
MITSUBISHI CNC
138
With the deceleration check function, a deceleration stop is executed at the block seam before the next block is
executed, preventing corner roundness by reducing the machine shock that occurs when the control axis feedrate is
suddenly changed.
8.1 Conditions for Executing the Deceleration Check
(1)
Deceleration check during rapid traverse
During the rapid traverse mode, deceleration check is carried out at the block seam before executing the next block.
(2)
Deceleration check during cutting feed
The deceleration check is carried out at the block joints (before executing the next block) during cutting feed when
any one of the following conditions is valid.
(a)
When the error detect switch (external signal) is ON.
(b)
When G09 (exact stop check) is commanded in the same block.
(Note)
The G09 command is issued in the same block as the cutting command. It is an unmodal command.
(c)
When G61 (exact stop check mode) has been selected.
(Note)
The G61 command is a modal command. The modal is canceled by the following commands.
G61.1: High accuracy control
G62: Automatic corner override
G63: Tapping mode
G64: Cutting mode
