Abstract
A machine-implemented method is provided for forming a release surface of a mold. The mold has a mold cavity confined by an inner peripheral surface defining a mold cavity axis. The method includes the steps of: (a) bringing a grinding surface of a rotary grinding portion of a jig grinder into contact with a part of the inner peripheral surface such that the grinding surface is inclined at a predetermined angle relative to the mold cavity axis, and rotating the grinding portion such that the grinding surface grinds the part of the inner peripheral surface; (b) separating the grinding surface from the inner peripheral surface; (c) changing relative positions of the grinding portion and the inner peripheral surface in preparation for grinding another part of the inner peripheral surface; and (d) repeating the steps (a) to (c) until the release surface is formed.
