Warm-up compensation system and method

A warm-up compensation system, comprising:

• a heating element disposed on a machine, wherein the machine comprises a spindle;
• a displacement meter configured to obtain a tilt angle of the spindle;
• a plurality of temperature sensors disposed on the machine;
• and
• a processor device electrically connected to the heating element and the temperature sensors, wherein the processor device previously analyzes the critical blocks of the machine, the critical blocks comprises a plurality of critical temperature sensed blocks and at least one critical heating block, so that the temperature sensors detect temperatures of the critical blocks of the machine, and the processor device establishes a relationship among a temperature change of the critical temperature sensed blocks, a change of the tilt angle of the spindle, and a temperature change of the at least one critical heating block along heating time, compensates the temperatures of the critical blocks of the machine according to the relationship, and determines whether a temperature of the spindle has reached equilibrium.

A warm-up compensation method, comprising steps of:

• (A) dividing the machine into a plurality of temperature-sensitive candidate blocks;
• (B) when the machine operates at a constant speed, using temperature sensors to periodically capture temperatures of the temperature-sensitive candidate blocks, determining that a plurality of critical temperature sensed blocks of the temperature-sensitive candidate blocks mainly affect an inclination of the spindle according to the temperatures of the temperature-sensitive candidate blocks and a tilt angle of the spindle, and recording a critical temperature sense information, wherein the critical temperature sense information comprises a relationship between a temperature change of the critical temperature sensed blocks and a change of the tilt angle of the spindle;
• (C) setting non-critical temperature-sensitive blocks of the temperature-sensitive candidate blocks as a plurality of heating candidate blocks;
• and
• (D) when the machine operates at the constant speed, using the heating element to heat the heating candidate blocks individually, finding at least one critical heating block that most affects the inclination of the spindle from the heating candidate blocks and recording a critical heating information, wherein the critical heating information comprises a relationship between the temperature change of the at least one critical heating block along heating time and the change of the tilt angle of the spindle, wherein the critical temperature sense information and the critical heating information serve as a basis of a accelerating warm-up compensation for the machine.
