ABSTRACT:
A method for making eyeglass frames from thermoplastic material and the like comprising the steps of drilling four holes in the blank and placing the blank on a first fixture having two locating dowels and two expandable pins. The external frame contour is then milled and all necessary contours are milled on the front, rear, sides and ends of the frame, reversing the frame on the fixture as necessary. Finally, the frame is removed from the fixture and placed in a second fixture which engages and holds the frame externally. Lense openings and lense grooves in the walls thereof are thereafter machined.
