RE: [CAD_CAM_EDM_DRO] Re: Lathe threading

Hmm I can see how you can use a cutter with less than 60 degree included
angle if the tool is positions so that one side is parallel to the 30
degree side of the thread but then this would leave the other side and
an incorrect angle. Can you provide more details on how this 35 degree
cutter is set up and used for 60 degree threads?

Hi,


In CNC mode the machine uses a one bit encoder mounted on the spindle
and
provided a cutting tool with less than the included angle of the thread
is
used a perfect thread is formed. e.g if the thread is a 60 degree
included
angle a tool of less than 50 degrees can be used to cut the thread. I
use a
35 degree tool because this is included in the tool list and I haven't
worked out how to program different tools yet.

Regards,

Terry
