Question

Change lead-in radius in Rough milling

Folks,

I'd like to change the lead-in radius when rough-milling. The cutter chatters because the radius is too small so I'd like to increase it. I've looked all over the place and cannot find any way to change it. Does any one know how to do this? BTW I'm on Creo 2, M100.

You didn't specify what type of sequence you're dealing with: volume mill, trajectory mill, etc. Makes a difference as to what parameters are needed for things.

If you are only seeing a small amount of parameters for editing, you might need to click the "All" button next to "Parameters". The lead-in radius on, for example, a trajectory milling sequence, is governed by the "LEAD_RADIUS" parameter. Also pertinent is the "ENTRY_ANGLE", which sets the portion of a full circle that the lead-in will traverse. You've really just got to play with these things to get a feel for what they do.

Ken,

The type of sequence is "Roughing" under the Roughing ribbon button. As I mentioned earlier, I've not found any way of altering the lead in radius.Milling Sequence - Roughing.png

The cheap, homemade arrow points to the lead in radius in the picture below.

The roughing module works quite well for what I want to except for this problem. Somehow, I have a feeling that it's dependent on the cutter diameter. I suppose the easiest thing to do would be to use a different diameter cutter. This would work in Creo, but not in the real world because I can't use anything else to machine the feature.

Best regards,

I have had some luck with the following options.

SMOOTH_SHARP_CORNERS - CONSTANT_RADIUS

SMOOTH_RADIUS - cutter_diam*.2

Try any and all variations for these settings if that doesn't help let me know I might have some other tricks to try.
