PENCIL PASS

[david b]

Hi everyone,

I have uploaded a file on the FTP site under mcam v9 folder called ELEC#3.It's a simple pencil pass but i can't get the tool to retract high enough and the tool gouges when lifting from one pass to the other i have an absolute retract set what am i doing wrong.

 

thanks in advance

Could it be something with the wcs? Just curious, I had similar problems once.

Neg. value in stock to leave is causing your

gouge. Quick fix would be to copy upper surfs

(Z+) and drive off them. Hope it helps

 

PEACE

I did not think of that thx Hardmill.But i dont see why the tool travells on the surface to get from one erea to the other. Surely the tool should retract to the absolute retract height?

You need to reduce the value of your "Gap Size" under Gap Settings.

 

Set the "Gap Distance" to 1mm and every stepover move larger than 1mm will do a full retract.

It should go without saying that I believe this response to be worthy of a new section entitled as expert tricks & tips.

 

I am not playing up to Glenn , but I do believe the time is right to flag the major benefit of belonging to this forum and to locate a cache for such invaluable information. Every so often a post or post reaction reflects so much more to the larger picture - however; this response can become easily missed, forgotten, or worse - never read at all. IE: the OT Coolant thread (who could argue the knowledge base and cantor?)

 

I know that I would probably add little to the mix, yet so many other members could well add volumns - please give this suggestion some thought.

 

The constant argument of cutter comp/how it works, negative stock allowances, thread milling, wear offsets, Wcs , comm porting, hard milling, Mazatrol programming, etc! - every so often we ask a question and receive a solution that satisfies or produces a specific or winning result. Let's say we put this up as a new section or perhaps linking to satisfy a specific question or request.

 

In closing I ask, what is a vector in regards to Cnc machining? and please be specific for a prize. (A former student layed it out like poetry - Can you?)

 

Note: As usual, ChrisM is not eligible for this prize but his response could well be cherished!

 

P.S. - winners that do not forward their mailing addresses are doomed to become abused in their Starfleet roles.

 

 

Regards, Jack
