Re: Mori Seki SL1 NC lathe programming

Cliff,

Blah, blah, blah & blah. Cloud the issue, duck, dodge, dance and dive.

As usual a simple question went way beyond the original post.

The Key was Keith's Mori-Seiki, SL-1, 2 Axis Lathe.

There comes a point where each person needs to determine where the line
is drawn when it comes to diminishing returns and adding processes.
With all the steps you are adding to Keith he is well past the point of
diminishing returns.

1) The more calculations and data input at the machine the more
opportunities for errors. That is why I wanted you to post your step by
step instructions so we could compare what each of us recommend to
Kieth for setup and programming. You knew that and that's why you won't
post it.

2) It is not necessary and in Keith's case counter productive to add
two levels of difficulty your recommended in programming and setup when
the machine control can't utilize the resulting product (code).

3) Whether Keith programs the tool nose radius or the center of the
tool nose radius around the contour of the part Keith will get good
parts.

4) Now you seemingly advocate adding another unnecessary step of
drawing a simple 2D shape in 3D CAD? On such a simple program as your
example that has a couple of lines and an edge break it seems counter
productive to draw it in CAD then export to CAM to assign tools and
tool path. Wasted time drawing a solid on a simple 2D profile when it
could and should be one step draw the tool path in CAM.

No 8 axis lathe here for Keith. his SL-1 is simple 2D grunt work so
keep it simple. I am confident Keith would rather make good parts fast
rather than time consuming pretty pictures of parts slow which produces
confusing code and more opportunities for mistakes on setups.
