Workholding and Hi-Tech Chip Containment System

Postby rawkstar320 » Mon Mar 04, 2013 1:10 pm

Hey all,

It seems a little quiet around here so i thought I would post some quick pictures of my latest creations! As a hobby, I do some product design consulting, which deffinitely contributed to purchasing the Zen. Well, I am finally starting my first *production* run and wanted to show off my preliminary setup. I designed some clamps with a counterbore on one side, and a 2mm lip on the other side to allow me to hold down HDPE bar stock. (1/2" and 1/4" thick). To mount the clamps to the table, I used 1/2" MDF and cut in some pockets that would hold a hex nut and screws to retain the hex nut. As you can see, I still need some blocks to support the backside of the clamp. I will try to post some DXFs someday soon.

Plastic chips are terribly annoying, and messy, not to mention difficult to contain. Until I finally get around to building a killer ZenClosure, I have developed a hi-tech chip containment system - built from the highest quality 8x10 Lexan, 8x10 Polystyrene and a ceral box. For lighting, I resurected a $5.00 lamp from Goodwill. It no longer had a base, so I just screwed it right to my workbench.

:-)

Nice! I still haven't got around to setting up my t-track, but I'll probably do it this weekend. It's funny that simply holding down the material can be such a big challenge!

Huge challenge to be exact. This project has over 54 setups, so I wanted to create a "jig" layout that was universal and repeatable (54 different programs, 2 differnt stock thicknesses, stock is the same width/length). With my little clamps that have the lip, I know that they will only cover 2mm at any given point on my stock - so I can set up my parts appropriately. No more "OH ****" moments when you have to start over because the clamps were in the way.....

Sounds like you really thought it out!

What's the project for? You said you do product design consulting?

Yes, I usually work through my website, http://jakedrews.com. But now that I am a full time engineer, I only work with a few clients. This particular project is essentially custom cookie cutters...but I cant really say much more than that. :-D Good ole NDA's.

I am hoping for a drastic increase in speed/accuracy when I get my new leadscrews (F8) and A+ zen spindle. I think I might even try to do a writeup comparing the two setups (Dremel vs Spindle, Regular leadscrews vs F8) but I make no promises!

That's awesome!

I'd like to do something like that. I'm a designer/drafter, but the work I do is mostly just small iterative changes to biomed products. I'd like to move towards product design and industrial design, but haven't figured out yet how to get into that.

Anywho, that's some cool stuff on your website!

Same thing here, I went to school for Product Design - but work at a company that makes Stamping line machines and dies (for heat exchangers). Someday I would like to do consulting full time, but its just too hard to give up a consistant paycheck, with great benefits...so...someday. I have to at least pay off my school loans first.
