Has anyone ran into difficulty with creating a Helical Entry to a Mill Volume with Volume Rouging in Creo 4.0 M030?

matt,

just click the add button and type it in the box for option name = enable_classic_nc_steps and in the option value type yes then hit ok. don't try and use the find because it won't find it.

might have to close out of creo and restart to get it t to work.

Hope that works for you.

Matt,

Seems to be working for me. What is your issue with the helical entry? need more details to help you.

I have a mill volume that is 2.250" deep x 3.250" w x 4.375" l.  It is being finished by a 500 x .03CR end mill.

 

Scan Type is Spiral

Rough Option is Pocketing

Ramp Angle is 2

Max step Depth is .125

Step over is .175

Helical Diameter is .125

Lead Radius is .125

Over travel is .125

 

The cutter profiles as I'd expect it to, but does not helical into the bottom slice as I am use to seeing.  It just plunges after profiling and cuts the bottom of the pocket.

 

Thank you,

Matt

Matt,

I don't think helical option works with the pocketing parameter. I usually do 2 sequences to finish a pocket because of that. The first sequence finishes the floor with parameters set to the same as yours except the rough option is set to either rough or faces only with a wall stock of the amount of stock you have on the wall or maybe a bit more stock so the cutter doesn't touch the wall. The second finishes the wall with parameters set to follow_hard_walls and profile_only  with lead in and lead out and cutter compensation on to finish the pocket wall.

I have never cared for the pocketing option because if I have  to drift  or have spring passes to get the pocket to size it wants to recut the floor also.
