Abstract
A numerical controller for controlling a multi-axis machine tool having three linear axes and three rotating axes obtains an interpolated tool direction vector by interpolating a tool direction command and computes multiple solutions for three rotating axes from the vector. The three rotating axis positions are computed by synthesizing these multiple solutions. The three linear axis positions on a machine coordinate system are computed by adding to the interpolated tool center point position the product of the interpolated tool direction vector, or a verified tool direction vector based on the three rotating axis positions determined by the rotating axis position computing means, and a tool length compensation amount. The three rotating axes are moved to the positions computed above and the three linear axes are moved to the positions computed above.
