Hello All,
I have played around with normal threading and I am starting to get some confidence, I am now looking at multi start threading via cnc and mach 3.
I last spoke to Hood about this here :
http://www.machsupport.com/forum/index.php/topic,10385.0.htmlMy questions are as follows:
1) Do I need to have controll of the direction of the spindle?
2) Do I need a special gear train for multi start?
3) Does mach 3 multi start thread by coming in at a different angle? Will I need to vary the speed?
I am using a cnc Sherline.
The thread I would like to cut is a four way o.75pitch 9.5mm dia - straight, not on a taper...yet.
Thanks,
Andy
