Replaced switches on two different weld positioners. The Atlas positioner is only a few months old and I don't know how old the MK one is (circuit board) but we have a few of the boards. I'm guessing they just live a hard life in the hands of a welder.
Tacking tools to hold tubing onto V-blocks and a badass rack for them. Setup the General Manager on the other Mill to machine the vise grips and, after watching me setup the other parts, decided he could program the racks too. Dude never touched a Mill before. #respect
Fusion welding on a positioner. Finally got a long enough run of something to figure out a good setup. Turned up the pulser to 100ppm to narrow the weld down and agitate the puddle; it seemed to work. These are adapters for purge gas on our orbital welders.
One of today's projects - two 304 SS vise stands for the clean room. Actually put some effort into the welds but feel free to make fun of them (I usually just weld as fast as possible with little regard for evenness). The machinist made the lower mounting holes way too tight so I had to be on point with the concrete drilling. Thanks @bagofwelds for the mini lesson
We needed a half dovetail cutter in a pinch for our giant cnc VTL and our cnc lead whipped this up real quick. The VTL operator had serious doubts; apparently it's been cranking out awesome oring grooves on the same cutter for dozens of parts. I sure appreciate these guys making my life easier.
When EH&S tells you the grinder needs to be setup like the left side because the #OSHA paper they printed out said so but, in reality, they didn't even look at the paper themselves. In other words, set it up the way I did or you are wrong. His follow up when corrected was to let me know that 3M wheels don't need guards #seriously#gohome
Sometimes I'm a #plumber. Partially because I don't want some rando hanging out in my house and partially because I want it done right. Was way easier after taking the sink out. #plumber#plumbing#corrosion#rust
Safety rail for the vertical lathe that @kwolls designed and had bent/coped. Luckily I got to weld it up and repurpose some scrap for a cupholder. Also added some hooks for air/coolant guns. Used a positioner for the first time on the cupholder. Had to keep @bagofwelds booth warm while he is gone :D Next week is paint and install.
Someone dropped the #piranhaiii tungsten grinder, which is made of rectangular steel tubing, and somehow bent the motor shaft. So the $300 diamond wheel wears unevenly/prematurely. They have a sealed motor "upgrade" with new backplate that replaced the fuse with a breaker (bonus). You can see the old motor had a nut plate they taped to it for easy assembly that will not fit on the new one, so @bagofwelds tacked the nuts to some washers and I super glued them to the motor mount plate and the motor spacer to to the housing (which it turns out is a factory trick judging by the glue marks). New wheel and this thing is good as new. Don't worry, I soldered the green wire before final assembly.
Example of SolidCAM's high speed iMachining in action using an 1/8" endmill to cut some slots. Not only does it automatically calculate the appropriate speed/feeds/RDC/ADC based on material hardness/machinability and endmill material/projection/flute count/etc, it also continuously varies the feed for each section of the tool path. I.e. to take advantage of straight sections that could utilize smaller RDC. It may not be as beginner friendly as hsmworks but it packs some powerful automatic roughing algorithms. Got some really good feedback on tool life too (cutter sounds great in this). A warning about high speed tool paths: make sure your machine can handle it from a processing/lookahead standpoint and that it can accelerate/decelerate quickly enough to hit those speeds as well. The Okumas we have are .56g machines and lookahead isn't even in their vocabulary, so there hasn't been a hiccup yet. I worked with a machine (2014 Haas VF4) that could not handle this type of toolpath.
