Radial and axial dimensions of cavity and core.

Plastic part size (mm)		Calculation formula	Core or cavity working size (mm)
Radial size of cavity		AM+^ξz = {(1 + S)AS-X△}^+ξz
	Radial size of core			BM-ξz = {(1 + s)AS + X△}-ξz
			Radial size of cavity			HM^+ξz = {(1 + s)HS-2/3△}^+ξz
			Axial dimension of cavity			hM-ξz = {(1 + s)hS+2/3△}^-ξz
