Method of optimizing the functioning of a machining center through adjustment of its temperature

A method of optimizing the functioning of a machining center for machining, at least one piece, by removal of material by means of at least one cutting tool, the machining center includes a number of components, such as a frame and at least one motor elements for producing actions of driving and displacement of at least the cutting tool and the piece, and implements an installation for lubricating and cooling the cutting tool and the piece by a lubricant, the method comprising:

• determining at least one temperature reference value for the lubricant, such that the machining center functions in a stable way;
• changing a temperature of the lubricant in such a way as to adjust it to the temperature reference values;
• changing a temperature of at least one of the components of the machining center in such a way as to bring the temperature of at least one of the components to a value closer to the temperature of the lubricant, and brings the temperature of at least one of the components closer to the temperature reference value;
• confining the machining center at least partially in an enclosure with at least two openings for entry and exit of an air current;
• and
• circulating the air current in the enclosure through agitation at the level of at least one of the openings, a temperature of the air current having been changed beforehand in order to adjust it to a value substantially equal to the temperature reference value.
