Program Examples
32
Note also that the program has a block-deleted M99 command in the second-to-last line.
This lets you turn on block delete if you want the program to run only (1) time.
Command
G105
in
MDI
mode to load a bar and push it to the initial push length. In this
example, the initial push length includes the 2" length to machine first and a 0.025" facing
allowance.
Before you run this program for the first time after you load a bar in
MDI
mode, move the
cursor to the block after the first
G105
command in the program to bypass the first push.
Remember that after the initial push, the bar is already in position to start machining.
