Here we go again . . . MK4

Next up was a little job I'd been putting off until I'd got to grips with F360. These are going to be inserts which fit inside the extrusion to connect the bed uprights. I'm sure there are many ways to make these parts but I decided to get some practice on adaptive tool paths. Here is the first of 16 parts:


It all started with a large 8mm sheet:


I then machined 2 edges so that the parts would be the right length:


Then over to the chop saw to rough them out to width:




Next part tool a while - machining the 3rd edge on each part in turn:


Not sure if this is good practice or not but the 4th edge I did in small batches:


All to size . . .


Then 6.8 mm holes machined (ready for M8 tap):


Now onto the angled sides. I made a fixture to hold the parts which had 2 datums for alignment:




The fixture was dropped into the vice each time and aligned in Y (fore/aft) by eye as this is not critical. It only needed to hold the blank in the correct X (left to right) and Z (up and down) position.

Then a 2D adaptive to rough it out. I had intended to do a cleanup but this doubled the machining time and the parts fitted fine with just the roughing:


The adaptive took about 2.5 minutes which was not too bad. I've done 8 parts, 8 to go . . .
