Operation for a deburring brush

Valued Contributor

Hi all, 

 

Im hoping somebody can help to point me in the right direction. 

 

I need to create an operation to use a deburring brush tool like the ones found here: http://www.deburringtechnologies.com/products/CrossholeBrush.html

 

Essentially the operation needs to work as follows:

- I need the tool to feed to the bottom of (or slightly through) a through hole with the spindle speed at 0.

- Holding this position, the spindle then needs to spin up to 10,000 for a few seconds. 

- Ideally the spindle then needs to return to 0 before retracting back out of the hole. 

 

My first thoughts are to use some kind of drilling operation with a dwell. My only issue is that the spindle speed needs to be at 0 whilst passing in and out of the hole on the engage and retract. 

 

Anybody done anything similar?

 

Thanks,

Adam

Adam,

 

I guess you need a DEEP_HOLE_DRILLING operation. In this case the tool can enter the hole to defined depth with 0 RPM or like the attached sample 50 RPM CCW, then speeds up to a desired cutting RPM CW, moves to the final depth, then dwell, stops the spindle and retracts out with 0 RPM.

I hope the attached images can help for settings and post processor output since I do not have the English version.

 

Kind regards,

Majid

It sounds like good use case for GENERIC MOTION operation. Once defined operation with sequence of sub-operations can be stored as a template and easily reused after that.

 

Other simple solution might be custom drilling cycle, but you would have to define it in postprocessor.

Generic Motion is the way to go.

 

Used it a few times for back counter boring tools that go thru a hole and flip open. They require a few speed changes, dwells and spindle reversals.

 

You won't be disappointed.

The easy way is to do this with Generic Motion like Marek says, but you can also create custom cycles in postbuilder for hole making operations. See that attached zip file for an example.

( The custom cycle can also be sourced so you don't have to put it every post. )

(just to know, currently there is a little problem in GMC (vector issue) but should be fixed in NX1847)

Is there a description of the generic motion problem available somewhere? I wonder when it started and what the detail is.

You can do this with Generic Motion or the Legacy Point-to-Point operation.

Thanks all for the replies! I achieved what I wanted using generic motion control. 

 

The only problem is that the users that will require this operation do not have multi axis licenses. 

 

I will try to work out how to use the point to point legacy operation to achieve the same. 

 

Thanks again!

Even though it is under multiaxis I think it still works for 2.5x license.

Been a few years since I've had that MACH bundle so I can't confirm.
