Pocket Entry

[specprogrammer]

How do I enter a pocket using ramp or helix? I put the parameters in and it is still plunging. using a non center cutting end mill.

Make sure the tool is small enough to fit.

 

Make sure your XY clearance is small enough. (the distance to stay AWAY from the walls when ramping)

are you using point geometry along with a contour to force a start point in your pocket?

Thats it! Thank you.

I always thought that you had to use a center cutting end mill to ramp or helix.

Please someone correct me.

Hey we got guys like that Thats how we started an Inspection dept.

 

bucket, I ramp al the time, even face mills, check out Iscar feed mill, KICKS METAL

we run it at 300/600 IPM .06 depth cuts in 30/40 RC 4140 and yes with ramp

You can ramp [or helix, which is just a round ramp] with a non-center cutting tool as it is the cutting edge of the tool that is encountering the material to be machined [remember that "flat" endmills aren't really flat on the bottom]. You just need to keep the angle reasonable and you should be cool. Plunging, on the other hand, can be a problem...

 

 

Chris teh non-center-cut endmills suck

Yeah Bucket you can even do it when inserted endmills most have an angle allowable in the selection page when you look in the book. Some areas saml las 3 degree some are as great as 30 degree I play attention to that also when buying inserted cutters.

 

I also cut tapered keyways in big shafts like 8 to 24 in diamater sure beats trying to hold the shaft at an angle.
