Terry,

Guess my machines up to now have been on the sloppy side. I used to do bi
directional surfacing, cut to the left, then to the right etc. I get all
kinds of patterns and strange bumps, I would guess from the backlash in the
axis drives, the gibs, and from flexing in the machine. Once you decide to
spend the time and cut all in one direction, you can literally double your
machine time. The faster your G0 speed, the better. Because my operation
straddles the line between a hobby and a commercial venture, I often machine
many medium size lots. 500 is a common lot size, I often do 2500 part lots.
If you can shave even 2 seconds off every part you make, it really adds up.

At 60 ipm, a move a quarter of the way across the bridgeport's table may
take close to 10 seconds. Do that 1000 times and.......
