Abstract
Provided is a servo controller that can prevent an unnecessary cut from being generated during oscillation machining. A servo controller which controls a machine toolthat turns a workpiece W by cooperative operation of a plurality of axes includes: an oscillation command generating unitthat generates an oscillation command for causing the workpiece W and the toolto relatively oscillate; a deviation deducting unitthat applies the oscillation command to a position deviation based on a moving command for causing the workpiece W and the toolto relatively move, and deducts a steady-state position deviation; and a learning control unitthat calculates a compensation amount from a position deviation based on the moving command after deducting the steady-state position deviation.
