ABSTRACT:
A method of forming a pattern includes providing an actual core having dimensions which are different from dimensions of an ideal core. A best fit spatial relationship of the actual core to a spatial envelope for an ideal core is determined. Locating surfaces in a die are moved to positions, at least some of which are offset from ideal core locating positions, in which the actual core is positioned in a best fit spatial relationship with the spatial envelope for the ideal core. A plurality of motors may be utilized to move the core locating surfaces to desired locating positions. The actual core is positioned in engagement with the core locating surfaces and a flow of wax is conducted into the die. If desired, a best fit spatial relationship of the actual core to a die cavity may be determined, rather than a best fit with an ideal core.
