    摘要: The present invention provides a numerical control system employing an automatic tuning section for automatically tuning control parameters, such as position deformation parameters, corresponding to the numerical control of the position of a table using a servo loop. In particular, the present invention provides an apparatus for, a method of, compensating for machine deformation and ballscrew errors produced by the play resulting from loose connections between a ballscrew and a moving table engaged thereto. The present invention provides a first and second change slowing means for respectively changing the compensation amounts of the machine deformation and ballscrew deformation error amount stored in a numerical control apparatus. The first and second change slowing means allow the machine deformation and ballscrew deformation error amounts, respectively, to be combined with a position command signal output from the numerical control apparatus to form a compensated control signal in order to control the positioning of the table with high accuracy.
