High precision temperature and contaminant control for precise machine tool positioning

A contaminant control system comprising:

• a source supplying a gas flow;
• a channel fluidly coupled to the source to direct the gas flow;
• a pressure sensor disposed within the channel;
• a machine tool comprising:
• an enclosure comprising:
• moving components disposed within the enclosure;
• an inlet fluidly coupling the channel and the enclosure;
• and
• at least one outlet to direct the gas flow out of the enclosure;
• and
• a cutting tool disposed outside of the enclosure and operably coupled to the moving components;
• a controller operably coupled to the source and the pressure sensor;
• a temperature probe operably coupled to the controller, thermally coupled to the moving components, and configured to measure a temperature of the moving components;
• and
• a temperature conditioner fluidly coupled to the channel and operably coupled to the controller, the temperature conditioner configured to condition a temperature of the gas flow based on the temperature of the moving components,
• wherein the temperature conditioner is configured to heat the gas flow,
• wherein the gas flow prevents at least some contaminants generated by the cutting tool from entering the enclosure.
