One of the biggest mistakes made in machining a part is starting out with the wrong operation, before you start machining a part thing about each step it would take to get the job done, starting out with the wrong operation could end up in a nightmare! For example, if you have to drill a hole on a angle in a Bridgeport and it requires you to tip the head, do it last if possible. If an operation requires you to move the vice on a angle do it last, you don't want to have to reindicate the vice over and over again or tram the head over and over again. Try to take the time to study the dwg. and learn to think ahead, say for example if your facing a long part in a vertical mill and the cut takes about 4 to 5 minutes or even 1 minute take that time to thing about the next operation and the one after that and recheck your dimensions, don't sit on you but and look at the clock.

This fixture weldment can be used for long and heavy work pieces. The design incorporates a "sill" that is machined at the same height as the bed of the vice. Use of a 1/4 - 20 socket head cap screw and lock nut as the stop. The fixture is cut keyed to fit the table slot and fastened with 1/2 -13 socket head cap screw.

When trying to face mill deep cuts on top surfaces of plastic is it best to do a frame cut using a climb mill pass first before facemill large cuts. This will stop the plastic from chipping on the edge. (This is very true with delrin.)
