Abstract
A method for machining a hold-down pressure shoe that conforms to a preselected pattern on a workpiece for firmly maintaining the workpiece against a surface of a machine so that the workpiece may be moved adjacent a rotating cutterhead without elevating it from the surface, comprising the steps of: programming a computer to control a cutting means for shaping the preselected pattern; and operating the cutting means to cut the hold-down pressure shoe into a shape which corresponds with the preselected pattern.

A method for preparing a hold-down pressure shoe that uniformly engages and precisely conforms to an external contour of a workpiece surface so that the workpiece surface may be moved adjacent a rotating cutterhead blade of a machine without elevating it from the surface of the machine, comprising the steps of:
- selecting a pattern for the workpiece surface;
- programming a computer to control a cutting means for shaping the selected pattern on the workpiece surface;
- and
- operating the cutting means to cut the hold-down pressure shoe into a shape that is the negative profile of the selected pattern on the workpiece surface.
A method for preparing a hold-down pressure shoe that firmly maintains a workpiece against a surface of a machine so that the workpiece may be moved adjacent a rotating cutterhead blade without elevating it from the surface, comprising the steps of:
- selecting a pattern;
- programming a computer to control a cutting means for shaping the selected pattern;
- and
- operating the cutter means to cut the hold-down pressure shoe into a shape that is the negative profile of the selected pattern, wherein prior to cutting the hold-down pressure shoe, the cutting means is operated to cut a template into a shape having dimensions that correspond with the selected pattern, and then using the dimensions of the cut template to make the hold-down pressure shoe;
- and
- operating the cutting means to precut the cutterhead blade into a shape that corresponds with the shape of the template.

- programming a computer to control a cutting means for shaping the selected pattern on the workpiece surface;
- operating the cutting means to cut a template into a shape that corresponds with the selected pattern on the workpiece surface;
- and
- operating the cutting means to cut the hold-down pressure shoe into a shape that is the negative profile of the shape and dimensions of the template.
A method for preparing a hold-down pressure shoe that firmly maintains a workpiece against a surface of a machine so that the workpiece may be moved adjacent a rotating cutterhead blade without elevating it from the surface, comprising the steps of:
- selecting a pattern;
- programming a computer to control a cutting means for shaping the selected pattern;
- operating the cutting means to cut a template into a shape which corresponds with the selected pattern;
- operating the cutting means to cut the hold-down pressure shoe into a shape that is the negative profile of the shape and dimensions of the template;
- and
- operating the cutting means to pre-cut the cutterhead blade into a shape which corresponds with the shape of the template.
A method for preparing a hold-down pressure shoe and using the hold-down pressure shoe to firmly maintain a workpiece against a surface of a machine so that the workpiece may be moved adjacent a rotating cutterhead blade without elevating it from the surface, comprising the steps of:
- selecting a pattern;
- programming a computer to control a cutting means for shaping the selected pattern;
- operating the cutting means to cut the hold-down pressure shoe into a shape that is the negative profile of the selected pattern;
- and
- operating the rotating cutterhead blade to cut the workpiece into the selected pattern while simultaneously positioning the cut hold-down pressure shoe adjacent said workpiece such that it continually engages said workpiece during cutting.
