Ron, that's a great pic! What memories. Pull that mainsheet in!
Metal is .071 thick, supposed to be 14 gage .075". We have been learning. On smaller cuts, pockets need to be at least 3/16" wide, or else it's better to just do 1 cut straight down the centerline. We are using cutter comp on cuts that are not just single line, to keep the kerf inside the lines. Our machine has stepper motors, which limits feedrates to 175 ipm. Should cut up to 240-270ipm or more at the .071 thickness, BUT, a big But, we have found that for tight detail cuts with a lot of geometry directional changes, to slow our machine's feedrate down to 50 or 60ipm. This greatly increases the controller/machine to be more accurate in following the geometry. I know of this from working with CNCs since 1978. The newer machines have acceleration/deceleration tables, and can look ahead in the code to know when a "hard right" is coming up. This Torchmate does not have that, and it struggles with tight stuff. Accuracy comes with slower feedrates on most machines. The parts I pictured are about 8" or 10" square. It's when you try to cut them in 4" square that you really have to pay attention. We are starting to make separate files for the smaller 4x4" stuff, mostly single line cuts.
I have to admit, my young brainy student worker has really taken to Fusion 360. that's a good thing because in his later classes, he'll have a good head start. I still want to finish a working post processor for Mastercam.
Church was great. BBQ luncheon after church with potluck. So much food! Worn out from yesterday. Had bbq yesterday at wedding, and today too, but it's OK, we are Texans and it's ok to have bbq for days in a row. Just makes you smell a little like burnt post oak. LOL
Need to try and go make amends with the cat, to let her know she can still trust me. I did yell at her, and she was trying her best to get away, but I had closed off her exit....I'm a dog person. Cats are nobody's forte. You might think so, but they'll throw in a twist when you least expect it.
Yes on the dross. Not real bad, most would come off with a heavy duty scraper, but a grinder would do a better job.
