Re: - stree relieving

These notes are correct. Generally stress relieving
is unnecessary and to get it right the process must be
controlled with reasonable accuracy.

For my cnc router I plan on welding a rectangular
frame of 2 x 3 x 1/4 wall tubing. Then I will stress
relieve the weldment in a flat fixed position. Next
the plan is to blanchard grind the top and bottom to
minimum clean up, asking the grinder to hold flatness
and parallelism to a best effort (+/- .005). I will
then drill and tap the holes for the x-axis linear
guides on the bottom of the frame. The top of the
frame will get tapped holes for mounting a cast
tooling plate, facilitating a replaceable work
surface.
