4.4 “G70” FINISHING CYCLE
The “G70” function activates the finishing cycle. This function can be used after the three rough machining
cycles G71, G72 and G73.
The finishing cycle consists of just one block and can contain these codes:
• P => Number of first block of the profile to be finished.
• Q => Number of the last block of the profile to be finished.
• F => Finish feed.
Before activating the finishing cycle G70 the tool must be positioned in the same point where the rough
machining cycle G71, G72 or G73 started.
At the end of the finishing cycle the tool returns to the starting point and the NC runs the next block
There are two possibilities for the feed used in the finishing stage:
- if the whole profile is to be machined with the same feed, just specify this value inside block G70 (with
parameter F)
- if various feeds are to be used on the profile, these must be specified in the profile rough machining
(these feeds will be ignored in the rough machining but activated in the finishing stage)
