Title: X-Z-Theta cutting method

Abstract

A method for machining a workpiece. The method includes the use of a rotary cutting tool mounted on the end of a movable arm. The arm is adapted to move in a plane perpendicular to the axis of rotation of the cutting tool. The cutting tool has cutting teeth to cut chips of material off of the workpiece in a predetermined size and shape to facilitate better removal of the chips from the workpiece. The teeth can be of different type and length to permit the tool to both rough cut and finish cut the workpiece during machining. The total depth of cut is divided by the number of tool teeth, so that the longest tool always performs the finishing cut.

  • To apply hard cutting particles, for example of tungsten carbide, on the surface of the cutting edge of a cutting tool, such as a saw blade, a drill, or the like, the cutting edge is partially melted by an energy beam, for example a laser beam, or an electron beam. A laser beam is preferred since, then, the process can be carried out in air, or in a protective gas atmosphere, rather than in a vacuum. The beam partially melts the cutting edge and the granules of the hard metal particles, preferably in a random grain size of between 0.3more » to 1.5 mm is permitted to run down, over the partially melted surface, excess being collected for reuse; alternatively, the partially melted surface can be dipped into the granules, and permitted to solidify.« less
  • There is provided a method and apparatus for upwardly excavating a shaft through destructible underground rock. The cutting operation is carried out by full face boring without relying on blasting. An operation for supporting the shaft side wall is carried out by means of frame segments loosely following the advance of the bit. The cutting operation and supporting operation are independent from one another. The diameter of the bit is contracted after the cutting operation to allow the bit to be lowered down through the frame segments.
