Dynamic selection of appropriate mix of coolant and lubriction for metalworking

A lubricant-coolant mixture selection and application method for a metalworking of a metallic surface, comprising:

• measuring surface roughness of the metallic surface;
• generating data indicative of thin-film lubricant rupture conditions;
• determining:
• a lubricant film thickness for the metalworking based on the surface roughness and the data,
• predictions of a chip formation pattern of the metalworking and where the chip formation pattern leads to chip impact on the metallic surface,
• a heat generation prediction of the metalworking from tooling specifications and operational parameters, and
• respective coolant and lubricant concentrations of a coolant-lubricant mixture of the metalworking from coolant and lubricant specifications;
• and
• operating measuring, imaging and tooling components of a system for executing the metalworking based on determining results to apply the coolant-lubricant mixture to the metallic surface for preventing thin-film lubricant rupture.
