High Speed Cutting Functions

[tilikoom]

Hello eM,

Looking for any feedback on Fanuc's 'AI Contour Control' function. While tasked with cleaning up some of our posts, it was discovered that one of them is generating in the header section this command:

G5.1 Q1 R10

The programmers and operators all refer to it as "smoothing", and claim they are using it to control surface finishes, mostly with complex parallel toolpaths. It became a topic of discussion after one programmer complained about having to toggle the R value manually, and asked if we could somehow adjust it in the source file.

After some research it is not entirely clear if we are 1) using this command properly, 2) if it should be in the header, and 3) if this is a good way to control surface finishes.

Firstly, it doesn't appear that we are using it as a "smoothing" function per the Fanuc manual B-63944EN 310A5 as shown in the first photo. We are using it as a 'Machining Condition Selecting' function as shown in the second photo.

Secondly, should this command be permanently baked into the header, or activated within individual toolpaths only when needed?

Thirdly, is this a recommended method of controlling surface finishes?

Would love to hear about anyone's experiences with this command. Sorry in advance if anything was overlooked.

Thank you

Mpmaster has it in it as misc integers.

 

In it works in the header unless you hit reset. But normally it should turn off after each tool.

our post has it baked in but uses something like if nextdc<0 [g5.1q1]. In the tool change block.
