    The results of cutting fluid testing through subsequent hole making operations are presented. AISI 316L stainless steel specimens were machined with drilling, core drilling, reaming and tapping using HSS-E tools. The effect of different lubricants on cutting forces and power was investigated in connection with the development of vegetable based cutting oils. Results show that drilling and tapping qualify as operations in which cutting forces can be resolved within one test when they differ by less than 1 percent by taking 6 repetitions, and measurements could be repeated with relative standard deviation lower than 2 percent. Reaming produced larger experimental spreads, depending on the fluid and its effectiveness in reducing built up edge. Cutting force testing in different subsequent operations has provided results valid for a broad range of applications in a relatively short time, allowing development and testing of vegetable based oils of equal or better performance than a reference commercial mineral oil.
