Burr formation, average specific cutting energy, surface roughness, and tool wear were analyzed and compared. Compared to dry machining, use of scCO 2 MWF reduced burr formation in both materials, reduced surface roughness by up to 69% in 304 stainless steel and up to 33% in 101 copper, tool wear by up to 20% in 101 copper, and specific cutting energy by up to 87% in 304 stainless steel and up

Dental materials: Milling cutters for titanium etc. l

For example, a machine with relatively low power and high rotational speed has to allow for space to deal with a high chip volume and thus can usually only accomodate two or three cutting blades. However, if a rather slow machine with a high torque value is used for machining, that tool can be equipped with six blades or more.
