22.6 AUTOMATIC OPERATION RESART
22.6.1 Program Restart
This function specifies Sequence No. of a block (number of blocks
between the top of the program and the block to be restarted) to be
restarted when a tool is broken down or when it is desired to restart
machining operation after a day off, and restarts the machining
operation from that block. It can also be used as a high-speed program
check function.
There are two restart methods: the P-type method and Q-type method.
P TYPE : Operation can be restarted anywhere. This restart method is
used when operation is stopped because of a broken tool.
Q TYPE : Before operation can be restarted, the machine must be
moved to the programmed start point (machining start point)
