Surface Rough Pocket

Recommended Posts

The toolpath here is a "Surface rough pocket". The toolpath looks very nice except the plunge! I just don't understand why most of the legacy toolpath's don't support ramping!

The only way to avoid the plunge is to plunge outside containment.

It's a non center cutting tool, I can't plunge with it.

Mastercam is Ridiculous!!!

Same toolpath, as 3D contour with cutter comp off. Saved modified geometry. Do I have to make my own ramping?

Ridiculous!

Funny thing is: the original pocket g-code is 935 lines long while this one is 917 lines without filtering.

Lead In/Out needs be fixed so it points inside the pocket: I love and I hate Mastercam at the same time ;)

The Entry parameters have a few key settings for this ->

Minimum Radius -> Set as small as possible

XY Clearance -> Set as small as possible

if you're xy clearance is say .125 and you're machining area is .1 the entry will be suppressed | Likewise if the minimum radius is larger than the machining area - the XY clearance.

In 2021 you can also ramp in the lead in/out.  Wouldn't that work here?

I think that's only for contour, you could project geometry onto the surfaces to use contour.

Check the entry helix tab

Could be that the helix is too big to fit into that area..there is an option to plunge or skip pocket if helix won't fit..try making the helix values smaller. Also check XY  clearance. Make that number smaller

The entire toolpath is Entry, except the last contour at the final depth. The Helix is circular, it can't profile ramp.

Cimco's HSM addon looks promising. Only if it worked correctly, direction of cutting does not work "both ways" and it does not recognize "rest stock" correctly!
