MasterCam: Complex Second Operation (Multi-Op Program) with Full Explanation of Features & Workflow

In this video we spend a little more time exploring Second Operation in MasterCam. Features include: Multiple Toolpath Groups, Custom Stock Model Setup, 2D Dynamic Mill, Ballmill Chamfering & Edge Breaks, Thread Mill, Creating Tools, and Tool Library Management.
First Operation can be found here: • MasterCam: Complex Fir...

Thank you for making these videos and showing different methods to avoid problems. Question: How come when you showed the collision detection feature, mcam did not detect the collision on the fourth path?

[@artofthepart]

I believe there are some parameters in the drill command that allow you to set avoidance regions. However using the example shown in the video, MasterCam viewed all the stock as available material to remove. So it's actually doing exactly what we're asking it to do. Although, it would give us a warning if we hit a fixture we setup or if the tool holder collided with the part.

Your instruction method is very helpful and I am grateful for it. I am hoping to find tutorials on making 3D mold cavities and using some of those 3D toolpaths.❤

[@artofthepart]

Believe it or not, I'm actually working on some mold making videos right now for the students. I should have some content on how to convert a milled part into a cast component and then make a mold from it in SolidWorks. Then we'll take a look at programming in MasterCam. Should take me another week or two to finish.

I can't wait to dive into the content you're preparing Thank you for putting in the effort to create such valuable resources for us students. Looking forward to it!

do you have any tips for the facing toolpath to be more efficient? It will almost always do a air cut on the last pass even though the whole stock has already been cut.

[@artofthepart]

Hmmm, I've always had really good luck with my Face Mills cleaning up to Z0 on the final pass. In the example used for this video, I set the depth cuts to .01 and had a top of stock value of .015. The tool made two passes in verify. Maybe try troubleshooting with One Pass or One Way and divide your top of stock value into an equal number of depth cuts. For instance, .05 for top of stock with a .01 depth of cut should make 5 passes. That, or you might also have a finishing pass turned on somewhere. I think there's a tickbox in cut parameters or depth cuts that might be forcing an additional Z0 pass.

@@artofthepart my bad i ment when the tool is not big enough it needs to do multiple side steps and on the last side step it almost always does a air cut because there is no more material left.

[@artofthepart]

I might have something similar in my Intro to 5-Axis Programming video under the Business Card Holder Case Study around minute 31:00. I use a 5/8 endmill to face a larger surface and control using stepover percentage and entry & exit approach.

nice to see, but with optiRough you can mill all of the first operations in one, or not? time is money ^^

[@artofthepart]

Oh yeah, no doubt about that - I love OptiRough! This is just the first project for my CAD/CAM class so we're only focusing on the 2D Toolpath Gallery for new users. I also wanted to show off the power of Dynamic Mill and copying toolpath.
