I'm working on the attachments for the CNC build to connect the table to the rails. (Not important)
I'm making 11 of them so if I mess one up it's not a big deal.
Milling them in groups. First group is 5 of them. Second group is 6 of them.
Each set has @50 passes of the mill on the Y axis. And another 50 blind passes on the return. So 100 passes each set
I'm using a 5/8" name brand carbide mill bit at 500rpm taking 1.5mm cuts with a final pass of .5mm
I have a 4" handwheel with a 3.5" handle.
Halfway through the first set my forearm was screaming at me. It took me around 2 hours to make all the passes on the first set.
Determined to get the second set done I started out giving myself 4 hours so I can rest my arm between passes.
Side notes:
I'm using a combo machine.
My power feed on the Y-axis sucks for speed. No way would I use it. I'd still be cutting the first set after a couple days.
I have plans to add a stepper to the Y-axis so I can have a faster speed for milling.
INNOVATION
I used a temporary power feed and managed to get the second set worked out in an hour which includes a half hour making the first 12 passes plus 12 returns on the second set. So I made 38 passes, plus 38 blind returns, including a cleanup pass, in a half hour.
Wish I thought of this sooner.
