where to start

[CNCme]

Good Day,

 

Taking a look ahead at mondays progs and

Ive posted a zip named grip.zip, that

quite frankly I am having trouble finding

how and where to start. can you guys take a look and see....using 9.1 SP2 mill Level 2...and

quite possible one might need lathe and some

crazy holding devices

 

Thanks in advance

Good Day,

 

I have put this file in the Mc9 folder and

if need you could send E-mail

 

Thanks, again in advance

CNCme,

 

What does the stock look like? Are these parts cast or finish shape? How are you defining the stock for each one? Bounding Box works well to give you a cubical stock definition but if they are cast, you'd have to create geometry for stock instead of using the Job Setup. HTH

Tony I am puzzled as to the very question you are asking. If you are trying to consider movement on the bores then leave that to last if worried about flatness then leave mill or ground stock depending on the part. I think it is a part that can be done just need to think 2 or 3 operations ahead of the one you are looking at. I am thinking a woodruff cutter for the sqaure undercuts and work for the square making as many side from one set-up as possible for your start.

 

I have found in the past for locations of bosses on each side I make a male locating detail and use that round detail verse using the outside of a part for locating. I think the lathe would be more trouble that it is worth if not a full multi axis machine with live tooling. It might sound crazy but I am thinking a 4th axis part here to get as many operations done at one time as possible then all just 2nd, 3rd, and 4th ops from there and done. I would not punch my hole through to the bore but would pre drill then in the 4th axis set-up to keep all of my true postion tolerances in spec.

 

Good luck be happy for you when it say permantly employed.

I'm also looking at this file....I'm thinking 4th axis too...

and undercut cutters. I think that should work just fine. In fact I just made some parts just like that. But then we have a SMALL 4th tombstone on our little VMC and dovetail jaws
