- Here is a cool CNC Machining Technique. Titan places 2 strips of material into the vises, runs the machine and then pulls 36 parts out.

Found my self here at 3am (4 yrs after it was posted) looking up fixturing for our new venture in knife making, and had to stop and watch. After your interview last year with John Grismo, I have been hooked on both you & John learning the ropes. At 68+, I may never see a CNC mill in our mom & pop shop, but Titan you can really inspire one to think out side the box. & I thank you. I Follow every video from when back in Cal, to the new headquarters here in FlowerMound TX. I have signed up for the Academy, and as time allows, my first training session is the fixturing tutorial,,Thx again for inspiring both young & old,,,Bear
Worked with German brothers back in the 90s . They were doing this back then. Great ideas have no expiration date
Another wonderful video Titan you are so inspiiring even to a 46 year old failure like myself your back story is so inspiring in currently deep in the shit addicted to drugs and penniless the only highlight of my dull life is watchhing your great content
very informative video... I've always wondered how you speed up the production process without constantly loading and unloading the raw material...
Mutually beneficial work holding example!
Much appreciated!
Quick questions from a prospective cnc machine owner- the soft jaws are re-usable and accurate if removed from the machine? How were the individual parts held once they were separated from the large piece of poly? I'm learning about tabs and other techniques, but it looks like these parts are 100% cut and just held in the vice jaws by the parallel edges.
So are there no tabs to hold the parts in? I think that a 4x8 bed router is much better suited for this though. One large sheet. Make hundreds instead of tens at a time.
nice thought & tought thanks for video.
Excellent
Great Job
may i ask how was this part programmed? Was it set-up using all the work offsets and Looping the program? Or was the whole program just done on CAM?
How are you not throwing parts? I always sj clamp two at a time due to a brown shorts moment and a shattered window. Especially with the long jaws not supported between the vises.
Nice video, and nice setup. It would never make sense to machine 30000 polycarbonate parts Tombstone setup or not. it you were doing those kind of quantities of this (relativey) simple part wouldn't make way more sense to injection mold them.? That would also eliminate the need to remove the coolant from each lens, I am assuming that the cleaning of each lens is a manual process? Thanks again for the great videos
DimensionMachine injection moulding produces a lower grade of component though.
they needed something clear and pretty accurate considering these are just a snap on part
It would be better to run these on a cnc router
Well, I dont agree with that very broad blanket statement at all. Injection molded parts are known for consistent quality over runs of tens of thousands if the machine and process is set up properly. Not to mention the cost benefit over the long run. Higher up front costs, but if you need 30k of something like he is talking about you are not going to machine all of them, at least not IMHO.
Like a Lego: cheap, accurate, clear if that is what you want, and injection molded!
技高人胆大，不怕铣飞了啊！
Titan, how would you machine an A36 flame cut plate?. The surfaces were jaws clamp the part are irregular.
That's kinda a vague question. I machine a36 that's flame cut all the time. Most times i clamp it to the table with Lenske table clamps on some riser blocks made from aluminum. If the machining op requires a vice i would mill the 2 of the opposite sides with the same method i previously mentioned to prep the material so a suitable vice could clamp on to it.
So your raw material has to be machined parallel on the width first. Otherwise you would be throwing parts.
Just push that acrylic sheet through a table saw, 10sec a strip
I have tried this before but with not much success. Always had issue where two parts got most pressure and the weakest link would pop out. We tried controlling the width of stock and the jaws were machined in the vice of machine using. Worked okay in beginning but over time would fail. I now have the habit of never holding more than two parts per moving jaw. And or use mighty bite clamps for independent pieces. Just my thoughts. Have you experienced this same problem over time? Or with inconsistent material?
Leave material between parts until high cutting force operations are done. Or leave a thick deck. Flip and deck in smaller qty if you can’t hold more than 2 per vice. Bandsaw the strip into whatever number of parts you want to deck at once. Some things that have worked for me.
How do Toolex vices compare with Kurts?
I have always like the Toolex and the quick change parallel system that they have... but Kurt is Awesome also.
A 3 axis table would be better for that job
Pretty basic workholding if you have been around machining for any length of time. Try using a shorter end mill holder as well. The closer your tool is to the spindle nose, the faster you can feed it and the better your surface finish will be. Simple stuff guys...
Could be giving a human a job just to get by
man these are basic's who should every cnc machining operator should known at the first day.
Nothing special, everybody who can think would notice stuff like this.
