Workholding Techniques: Window Machining & Tabs for 3,4, and 5-Axis Applications!

Window machining and using tabs gets me excited! In this workholding technique, the raw material becomes the fixture, which means flipping for Op 2 is a breeze. This strategy can works great for 3-Axis, 4-Axis, and 5-Axis machines. Let's cover what window machining is, why it's a great strategy, and how we've used it. Hopefully this inspires or helps you create even better ways to hold your parts!

Who the heck binge watches vapid Netflix movies when you can binge watch NYC CNC! Crip editing, film quality, well articulated just brilliant thank you for the high quality material on a consistent basis!

As a self taught 1 man shop I wouldn't have had the confidence to get into 5 axis Machining with out all these golden video you put out!
thanks again!

Stealing the hot glue method when machining off tabs. I would never have thought of that! Thanks John!

Excellent video... you really are "paying it forward"

[alishiade]

I respect you more because you share your life experience in cnc machining, god bless you.

That PDF download system works well. Looks great. Branded QR codes! Very nice 😀

I always feel like I'm wasting my time designing custom workholding that I feels like overkill. I need to remind myself its part of the process and having a part not move saves way more time.

These are excellent, keep them coming!

I was just looking back at some of your old videos and I found a series about making bullets. But you only made the projectile and not the casings. That got me thinking now that you have CNC machines you could do an updated series on making dies for both the projectile and caseing of a bullet.

Tech Tip: if you went overboard with the hot glue you can just soak it in goo gone over night and blow whatever glue remains off with compressed air.

Imagine if there was a hot glue tool XD Maximum automation!

"Flopping parts look great on Instagram" LOL

You guys should figure out some way to work with Lofty Pursuits. They 're always talking about needing a smaller roller for their candy drops. That would be really interesting if you guys were able to make those.

Why are people like you showing these techniques and ideas to the world for a few likes and views on YouTube. You’ve not developed these methods, this is nothing more than plagiarism
