Abstract: The present invention relates to a control system and control method. The control system is applied to a machine tool and includes a horizontal monitor unit, a temperature monitor unit, a temperature adjustment device and a controller. The horizontal monitor unit is configured to measure a horizontal angle of a table and the temperature monitor unit is configured to measure a temperature information of a sensing area in a machining device. The controller receives the horizontal angle and the temperature information, then generates a compensation signal to the temperature adjustment device to change the temperature of an adjusting area in the machining device so that the horizontal angle of the table and the vertical inclination of the machining device are orthogonal to each other.

Abstract: The present disclosure provides warm-up compensation system and method. This method includes steps as follow. Critical area of a machine is analyzed, where the critical area includes a plurality of critical temperature-sensitive blocks and at least one critical heating block. Then, temperature sensors are used to detect the temperature of the critical areas of the machine. The correspondence relationship among temperature changes of critical areas, tilt angle changes of a spindle of the machine and temperature changes of the at least one critical heating block along heating time. The critical area of the machine is compensated in accordance with the correspondence relationship. Whether the temperature of the spindle has reached equilibrium is determined.
