ABSTRACT:
A grinding machine for grinding a woodworking tool shown as knife to a predetermined shape includes two main tables. The upper table moves toward and away in a Y direction from the grinding wheel and a lower table that moves left and right in an perpendicular X direction in relation to the face of the grinding wheel. The total of the two movements yielding a full, two dimensional planar movement. The upper table includes a movable holder for a template having the desired shape. A guide pin is mounted to a base plate that is also adjustable toward and away from the grinding wheel in a Y direction. The template on the upper table is engageable with the guide pin and is movable relative thereto in a full planar two dimensional motion to thus cause corresponding movement of the woodworking tool relative to a grinding wheel to grind desired shape into the woodworking tool. The grinding wheel is positioned to first engage the cutting edge of the tool or knife in a face up position. The operator standing in front of the machine views the cutting edge of the tool or knife in a face up position and the template as an exact replica as it would be running on the machine spindle. Prior art presents a 180.degree. mirror image from the present invention. In such prior art, the operator has to reverse his mental image of the machine spindle as he is viewing it.
