5 AXIS SWARF

Don't use one entity to define your upper and lower chains. Stay with the arcs in the corners and the chains where they are. By using one chain for the shape you give swarf a lot of freedom you don't want to give it. Here letting the geometry work for you will yield better results and the newer swarf would do much better IMHO if you have all the entities that are the shape verse one to cover many. Old School Swarf allows you to SYNC by entity that I have not been able to figure out with the new Swarf.

I used the 2 chains you had and just told it to go deeper and the motion looks much better with the new swarf, but the old school swarf with sync by entity looks much better and nicer.

Spoke to soon. I dug into this a little more you it got wonky on the back side. You had a small bad spline. I used blend spline to fix that and combine to the next one. Another thing I did was create points on all your entity and then sync to sync by point and it looked even better for the motion.

I also had to use the refit spline on some of them as they are very ugly.

Here is what the motion looked like in 2018.

Welcome to the forum Stephen! :thumbsup:

As with anything, there are many ways to achieve the same goal in Mastercam.

If you want more precise control of your tool axis, you could try using a Curve 5-axis toolpath with the bottom spline as your drive chain geometry.

You can create vertical lines between the endpoints of the top and bottom splines, then use them as your tool axis control vector lines.  It's a little bit more work but the vector lines give you much more flexibility.  In areas where you want the most control you can create node points along the upper and lower splines, then connect those points with additional vector lines.  This allows you to have maximum control of the tool axis when you don't like the output you get from the swarf toolpath.  :cheers:
