Abstract
A method of guiding a tool for machining a work piece of a material block, the material-removing work portion of the tool being guided to move along a first guide path while a further point on the axis of the tool, which is located at a distance from the work portion, is guided along a prescribed second guide path, whereby the five kinematic coordinates of the movement of the tool are fully determined.

A method of guiding a tool having a working portion, to machine a work piece of a prescribed shape from a material block, comprising the steps of:
- moving the working portion of the tool along a first guide path extending in an essentially planar guide surface of said block;
- intersecting said first guide path at a first point on an axis of the tool during said moving step, such that said intersection is maintained at a given orientation with respect to said guide surface;
- and
- moving a second point on said axis of said tool, which is located at a predetermined distance from said first guide path, along a prescribed second guide path.
The method of guiding a tool having a working portion, to machine a work piece of a prescribed shape from a material block, comprising the steps of:
- moving the working portion of the tool along a first guide path extending in an essentially planar guide surface of said block;
- intersecting said first guide path at a first point on an axis of the tool during said moving step, such that said intersection is maintained at a given orientation with respect to said guide surface;
- and
- performing an advance calculation, for each position of said first point on said first guide path and said associated orientation of said axis of said tool, to determine whether a geometrical envelope of said tool will have an interference with a surface topography of said work piece, and where an interference is found in a place other than the working portion of said tool, predicting a collision between said tool and said work piece.
