Michigan Technological University has conducted research on the appropriate dosage of cutting fluid in cutting, trying to minimize the amount of cutting fluid and the costs related to cutting fluid when the processing requirements are met.
In the test conducted by Ford Motor Company, they tested and studied the concentration of cutting fluid, workpiece material, tool type and geometric parameters, and analyzed the surface roughness of the workpiece, built-up edge and cutting force. , The most appropriate cutting fluid dosage was obtained through experiments. Thyssen Manufacturing Company of the United States has conducted research on the "minimal lubrication" processing technology, so that the cutting fluid flow or aerosol acts on the processing area through the tool, and the flow of the cutting fluid is controlled by the CNC program, which has achieved good results. Wang Chengyong and others used minimal lubrication technology to drill a variety of composite boards. When drilling aluminum-titanium multi-layer composite plates, the friction and wear of the cutting chips of the titanium plate will cause the hole of the aluminum plate to be trumpet-shaped. The test uses the least amount of lubrication technology, using coated tools and cutting and chip removal and reaming to reduce the width of the blade, increase the feed angle and use a stepped shaft to ensure the processing quality of the hole.
