Appendix A
Derivation of Formulas for Internal Thread Milling
R_e, β, and X can be found by a geometric analysis of the entry path.
This entry path is defined by the tool traveling along a circular path, with a radius of R_e about the point C.
R_e =	(R_i - C_L)² + R_o²
	2R_o
Triangle OAC enables us to simply solve for R_e.Note that OAC is a right angle triangle, and that:
OA = R_i – C_L CA = R_e OC = R_o – R_e
Pythagoras’ law states: OA² + OC² = AC²
Replacing actual values, we get:
(R_i - C_L)² + (R_o - R_e)²= R_e²
Simplifying, we get:
R_e =	(R_i - C_L)² + R_o²
	2R₀

Find the angle β.

sin
	= arc sin	(	R_o - R_e	)
			R_e
Therefore, β = 90° + arc sin		(	R_o - R_e	)
			R_e

Appendix B

R_e, β, and X can be found by a geometric analysis of the entry path.
This entry path is defined by the tool traveling along a circular path, with a radius of R_e about the point C.
R_e =	(R_o - C_L)² + R_i²
	2R_i
Triangle OAC enables us to simply solve for R_e.Note that OAC is a right angle triangle, and that:
OA = R_o – C_L CA = R_e OC = R_e – R_i
Pythagoras’ law states: OA² + OC² = AC²
Replacing actual values, we get:
(R_o - C_L)² + (R_e - R_i)²= R_e²
Simplifying, we get:
R_e =	(R_o - C_L)² + R_i²
	2R_i

Find the angle β.
β can be easily found using the same triangle:
sin β =	AO	=	(R_o + C_L)
	AC		R_e
β = arc sin	(	R_o + C_L	)
