I need help...we doing some maintenance on our 2007 MiniMill and have traced a growling Y axis to the servo motor. When the motor is out of the machine and energized, it vibrates like crazy. My guess is that the PID loop isn’t tuned properly, but Haas doesn’t have info on how to do it...any one out there ever tackled tuning them? The PID gain parameters look like they’re generic; all 3 axis have exactly the same parameters, including the Z, which has to also deal with the weight of the head. I’d also love to know what parameters other people’s machines have...they’re parameters 16, 17, and 18. (at Karve Machine Inc.)

Rocking the vacuum chuck from @pierson_workholding workholding again today. This time, it’s for a one off part made from MIC6. This thing is awesome 👌🏻 (at Karve Machine Inc.)

It’s been a long time since I ran a vacuum fixture, but the part is going to need it! It 9” x 11” and is made from 1/2” thick #MIC6 plate with details all over the top and bottom. I’m really looking forward to putting this #vacuum chuck from @pierson_workholding to use👌🏻 (at Karve Machine Inc.)

I don’t normally have music on in the shop, but I think #TragicallyHip all day is called for. Thank you Gord and rest in peace

I was a bit nervous but milling went off without a hitch. In order to get rid of the damage, I had to remove 51 thou from each side of the groove. (at Karve Machine Inc.)

And here’s the reverse engineered cam groove. It took a while, but it looks like the original groove was designed with arcs, so a bit of curve fitting and I’m good to go. Time to load up a cutter 😊 (at Karve Machine Inc.)

Time for some #HitachiSeiki surgery 😳 This cam is from inside the tool changer...the follower cam that rides in the groove on the top face blew up and destroyed the races...I now get to reverse engineer the groove with a probe and mill it wider. Whee... (at Karve Machine Inc.)

Working on some 2.75" C62300 #bronze round...I love how this stuff looks when it's machined 💎 (at Karve Machine Inc.)

You know it's been a long day when a .125" endmill is the largest cutter you've used all day. 8xD reach worked like a champ in 303 stainless 👊🏻 @harveytool (at Karve Machine Inc.)

Whipped up this #solareclipse watching rig...yes, that's shim stock. I didn't have any aluminum foil...plus, that's how machinists roll. #cameraobscura #solareclipse2017 (at Karve Machine Inc.)

🍁 Happy Canada Day 🍁 (at Edmonton, Alberta)

I don't know about you guys, but I think I need more nozzles #lathelife (at Karve Machine Inc.)

Squeezed in two trips to #WMTS this year. We talked with vendors and colleagues and learned a lot. I'm looking forward to implementing some of the things we saw 👍🏻👍🏻 (at Edmonton, Alberta)

What a day 😳 I was in the shop alone today and I had 3 machines running steady production...and they kept me running. Cycle times were between 90 seconds and 5 minutes...no time for rest 🚀 It's a great feeling having a super productive day, but the beer and BBQ afterwards was the best part 🍻 (at Karve Machine Inc.)

Clearance is clearance. Spot drilling with 25 thou per side on the tool holder... We have to be careful, but this seems like a mile compared to some of the other tight clearances we've run...like milling in the vise with only a thou left between the bottom of the cutter and the top of the jaws 😳 (at Karve Machine Inc.)

I finished this job earlier this week...there are 10 pieces here. 15 thou overall thickness with a 5 thou step around the perimeter. Whee 🚀

Sea of swarf...the result of 30 hours of finish milling on a P20 #steel mold. (at Karve Machine Inc.)
