ABSTRACT:
A vector conversion system for a numerical contouring control having a programmed machine path with at least two axial displacements .DELTA.X,.DELTA.Y, with a given cutter radius RCRAD. Master vector and slave vector computers are provided and arranged to operate in rotation and multiplication modes. The master vector computer receives signals which are a function of .DELTA.X and .DELTA.Y and delivers a counter rotational control signal and an RSS signal where RSS = .sqroot..DELTA.X.sup.2 + .DELTA.Y.sup.2. The slave vector computer receives the counter rotational control signal, a "0" signal and a signal which is a function of RCRAD, and delivers output signals IRC and JRC which are the orthogonal components of RCRAD. When these components IRC and JRC are interchanged, in effect, vector RCRAD is normal to the programmed machine path.
