Roughing sequence and plunge feed

Dear all,

When using the roughing sequence to rough a pocket I see there is no option to enter a plunge feed.

When using an end mill this is essential in order not to damage the flutes.

I've tried entering a ramp speed and specify explicitly a ramp angle of 90° (which is the default setting).

This has no effect on the resulting toolpath. The only feed applied is the default cut_feed.

The volume rough sequence does have this option but I can't use that sequence for this particular toolpath.

Is it possible to specify a plunge feed with the roughing sequence ?

Hi John,

If you are using the new volume milling sequence you must then specify the entry type defined to ramp as image below. With the old volume milling you just have to specify the ramp angle and speed and Creo understands you want a ramp entry ! By the way I'm still not using the new volume milling sequence as I don't find it very "logical" !

Merci beaucoup pour votre response.

I've now found that the new "roughing"-nc sequence, the one that uses a faceted model internally and which is the one I'm referring to, has a slightly different option set (in Creo 4 M010) as can be seen in the following screenshot.

Although I have now specified RAMP explicitly and specified a RAMP FEED (see the following picture)

I still no see a different feed in the cutter location file with respect to the first entry

It works on my System with Creo4.0 M10

in roughing If I specify a ramp feed different from the cut feed it shows as different. But it is not a straight plunge it is a helical cut into the part.
