Thread Mill Program

[october]

I am doubt to write a thread mill program for FANUC controller, this program using thread mill tool selected for 1/2-24 UNS -2B with 0.5" deep, what is the speed, feed and depth of cut to make a thread hole? What is the best hole to drill before thread milling?

What is the program different between using thread mill tool and single tip tool to make the thread milling on FANUC machine? Any example?

I look forward anyone to assist in this matter soon. Thanks.

Here is some good info for the cnc code. mmsonline article 0407cnc and the full macro

Hole size for thread milling is the same as for a cutting tap. The thread mill Mfg. usually has some information on using their tool.

Single point vs full thread mill. Just how many full revolutions around the hole. 1 for the full mill, and 1 for each thread for the single point.

See:

The last has lots of good information from www.threadmillsusa.com
