Abstract
A method and apparatus is disclosed for machining very fine, smooth cuts and grooves on minute surfaces such as single point bonding tips. The invention accurately aligns the axis of a reciprocating cutting wire in the direction of reciprocating motion and permits precise positioning and repositioning of the cutting wire on a work surface. The apparatus allows an unobstructed view of the wire in proximity to the workpiece during the alignment, positioning, repositioning, and cutting operations.
