Abstract:
1. A method of manufacturing a frame for either a door or a window, said method comprising: providing a plurality of elongated frame members; joining at least some of the elongated frame members to each other at ends thereof to form a generally planar perimeter frame surrounding an open interior for receiving glazing; the perimeter frame having a front frame surface on a front side of the perimeter frame facing forwardly from a common plane of the perimeter frame, a rear frame surface facing rearwardly from the common plane of the perimeter frame, an inner edge surface facing inwardly into the open interior, and an outer edge surface of the frame members facing outwardly away from the open interior; providing a frame mounting assembly arranged in said common plane for supporting the perimeter frame having at least one pair of parallel elongate work supports supported for movement relative to one another in said common plane to adjust a spacing therebetween, each work support including at least one clamping surface; clamping the at least one clamping surfaces against at least a portion of the outer edge surfaces of opposing ones of the elongated frame members forming the perimeter frame; providing a movable support mechanism supporting a machining device thereon which supports an interchangeable tool head therein; providing relative movement between the frame mounting assembly and the movable support so as to allow movement of the machining device along substantially a full length of the frame and laterally substantially a full width of the frame and at right angles to the common plane; and machining at least some of the front frame surface, the inner edge surface, the outer edge surface and the rear frame surface of the frame members forming the perimeter frame.
