Does anyone know the most important for produce a thread mill just it is just need to control the pitch only?? let say i need to produce a M16 x pitch 1.5 thread mill then the crest length is...

Thanks for your reply!!
Can you ask your friend is it have a wheel is grind few thread profile in a time?
Let say i want do 17 profile thread mills, but the tolerance at first 8 profile should be...

Thanks for your reply!!
If the thread profile is grind one in one time then will be take long time to produce one thread mills profile. It is possible to grind few profile in one time? This is...

Can any expert here can tell me the design of thread mill wheel?normally the thread profile is do it one by one?Now i use Walter CNC machine grind the thread mill and the thread profile is doing one...

Does anyone know that if thread mill use for roughing process then how many % of thread depth gonna be using??is it 70%??another question is in a thread mill process is it the thread depth is 100% in...

Thanks for your reply MR BILL,
As you say in in the perfect World, my program would cut the correct size thread with a Zero value registered for the Cutter Radius Compensation. After i try this...

How if i use below program to do a thread mill process is it correct??My thread mill diameter is 11.9mm want to make M16 pitch1.5 hole.If after thread mill process use go plug gauge to test still...

i mean is how can i offset the too diameter in machine??if i just write on the program G41 D01 but didnt offset the tool diameter also useless right?

How can i do a off set for Cutter compensation geometry offset register number (D) in fanuc??i want the machine recognize what is the tool diameter.

Thanks for your reply^^
another question i want to ask is the thread height is will affect the result of thread hole?Now my pitch is 1.5 so the thread height is 0.816 but after manufacturing the...

That's mean no need put F in program??i have using fanuc machining simulation software to test it step by step~from N40 G41 G01 X7.25 this step the thread mill already rapid move to right hand side...

i want to know below thread mill program is it suitable for fanuc machine (makino)~
