All parameter in form of variable while you make a
program of circular milling.
You just have to set only cutter diameter and hole
diameter. This program is automatically calculate path of rotation.
Now see step by step what i did.

Here i make only program for hole milling while i using climb milling, but whenever you make a program for boss milling you should change parameter of above program.
There are only two changes made in program in line no. 3 and line no. 14.
Now we are using G02 for climb boss milling and equation should be like this #102=#100+#101 instead of subtraction.
