  • Circuit for determining tool axis offset compensation
    Patent number: 3947667
    Abstract: A digital circuit useful in a numerical control system for determining during a preliminary execution of a program the axial components of a tool offset compensation. During a preliminary operation of the program, the sum of the squares of the axial components of displacement of the tool are compared to the square of the desired tool offset. When the sum of the squares equals or exceeds the square of the offset, the current values of the axial components of displacement are stored and used as the axial offset components during a subsequent execution of the program.
