creating a milling form tool

does any one know a easy way to creat a form tool by drawing it in nx and then put it in the library.or does any one have detailed instructions on how to define mill_10_parameter in creat tool.

Not that I am aware of, but you can create a custom journal to select a sketch, extract geometry, and build your form tool.

Using NX 8.0.3.4

Re: creating a milling form tool

Hello jv123,

 

what you wrote sounds kind of confusing.

 

There are so called parametric tools that you can use the generate a tool path.

There are the so called tool assemblies or 3D tool assemblies that you can use to perform gouge checks. Tool assemblies are NX modelling parts created following a special convention.

 

 

I depends on whether you got a 3D tool assembly of some tool vendor and want to use this in NX CAM or if you have a parametric tool and want to design a more detailed 3D tool assembly that is closer to the read tool. (long sentence)

 

What do you want to do? Do you use the OOTB MACH environment or a customized one?

 

Best wishes,
Joachim

There is a big difference between a form tool (user defined) and a 10-parameter end mill.

 

Form tools are positioned only by tracking points, and only used in some processors.

 

10-parameter milling tools are positioned be the shape of the tool, and can be used in most all the processors. To get the 10 parameters, I use a sketch - see attached.

Mark,

 

How do you link the sketch to the tool?

There is no direct link - I just use the sketch for convenience to calculate the tool parameters. In the tool dialog, I enter p1 for (X2), p2 for (Y2), etc. Since there are no expressions in CAM, there is no associativity here -- if the sketch changes, you need to enter the variables again. This is not an issue, since it would normally be a new tool anyway.

If you do this a lot, I would edit the sketch dimensions so that they match the tool inputs - for example rename p1 to X2.

 

I would post the part with the sketch and tools, but it's in NX 11.

Re: creating a milling form tool

Hi Mark,

We are experiencing a similar problem where we would like to define a tool based on custom geometry. Our tool cannot be parametrically defined using the 10 Param tool as the base curve has a non-constant radius.

I would like to be able to define the curve in a sketch and then use the sketch to drive the tool shape in NX. Are you aware of a solution to this?


Thanks,

Re: creating a milling form tool

You can use the actual shape of the custom geometry for simulation and material removal, but not to generate the path.

To generate the path, you need a parametric tool definition or a tracking point. 

To verify, simulate, or remove material, you can use either the parametric shape or the solid model assembly, if it is a library tool.

Hi Mark,

Ok, looks like there may not be an immediate solution. Thanks for your help.
