Machining control system and motion guidance device

A machining control system related to machining of a workpiece performed by a machining device in a state where the workpiece is movably supported by a motion guidance device having a track member which extends along a longitudinal direction and a moving member which is arranged so as to oppose the track member via a rolling element being rollably arranged inside a rolling groove and which is relatively movable along the longitudinal direction of the track member, the machining control system comprising:

• the motion guidance device;
• a table on which the workpiece is to be placed, the table being supported by the motion guidance device;
• and
• a controller, wherein
• the controller
• acquires information related to a damping ratio of a load vibration applied to the moving member when machining of the workpiece is being performed by the machining device as prescribed machining information;
• and
• generates, on the basis of the prescribed machining information, machining correction information causing a correction to be made by a machining tool provided in the machining device such that a machining speed of the workpiece, and/or a feed speed of an actuator for feeding the table with respect to the machining tool, is made to become slower as the damping ratio of the load vibration becomes smaller, and outputs the generated machining correction information to the machining device.
