Pencil toolpath

you should definitely experiment more with pencil, but as for limiting the toolpaths to the ones you want , use wireframe boundary to limit it's scope. Also we have the old school and HSM pencil toolpaths which usually differ a little . You should try both so in the future you'll know which is more appropriate for the case at hand. Actually when it comes to pencil the difference is minute. There is more disparity in e.g. Waterline and constant Z.

HSM pencil has a major difference over legacy: ability to limit it with a stock model.

Just check this video. There is a pencil example at 10:00 but whole video deserves to be watched.

 

Oh my! the beginning of this describes using a stock model created from surfaces to facilitate finish passes. I can see a great many uses of this in my future.

I think the issue maybe my parameters..

As said before you are going to need to limit it a little bit with some containment boundaries.  Make a sample file if you can with just the isolated surfaces needed and post it up.  We would be happy to help.  Generally speaking I have always just tweaked the parameters to get what I want.  Tedious and slow, but it usually gets the job done, not fully understanding what each setting does really slows down the programming process...  More lately I have been using the module works pencil in the multi-axis suite, seems to work a bit better with less effort most of the time.

Not knowing what your surface inputs look like.  If you are simply cleaning up a sharp or filleted corner between non organic surface shapes, or something of the like, you can actually pretty easily create geometry and drive a ball endmill tangent using contour.  I actually prefer that method when I can because you end up having 100% control of the end result.

And in 2022, you will no longer have to create surfaces from the solid first! You can directly pick individual solid faces to thicken within Stock Model.

I have also used the pencil strategy by  MW, as it can be made true 5-axis (provided you use a ball endmill).  3-axis pencil converted to 5-axis will fail as the new projection will tend to miss the spots. Been there, done it.

this is what im trying to pencil ..

It would be a bit tedious i think to isolate certain surfaces i think..

I will give it a go anyway..

Thought it could just be a matter of one pass along the crease of the parts..

Thanks!

I would do one feature and transform it to the other ones. I would never try to do each one individually. If you have the 5 Axis you can do it with Parallel one pass in 3 Axis for Tool Axis control using the solid edge and should work good.

This is really a simple question to answer unless I'm missing something. You can do exactly what you are looking to do with the old (legacy) toolpaths. Select  Mill toolpaths/surface finish/pencil     In the last tab of the toolpath settings, you can select "one pass" and it will accomplish what you are looking for. I would use "window" to select all the solid faces of one cluster, plus the floor face as my drive surfaces/faces to do the calculation.

I too would program just a single cluster and then transform the toolpath to the other locations.

How do you access the old legacy toolpaths in 2021?

 

Create your own Ribbon with them all added to it then you can access them anytime you want in a ribbon. Someone of the Forum showed me that one years ago.

I know of others who have added them to their RMB.

Not a good way to add them to the QAT or I just haven't tried hard enough to add them.

well i didnt know that..

I always thought some of the older legacy toolpaths still had their place in the world..

Thanks alot!!1

They all have their place problem is the work involved supporting Legacy and current method. We still cannot adjust the tool dialog box in 2022. Why is that because it carries legacy code and it is not as compatible with today's scripting so it stays like it does until everything is completely rewritten in a language today's OS can handle. That is the other issue today's OS has so much bloatware and spyware stuff in it majority of it is about collecting person information more than doing what it was originally designed for run a PC.

Is there a 5-axis pencil-ish now?
Or do one need to make something up like with the parallel you mention?
