Three rules for cutting thin parts

Three basic rules for machining thin components in the aerospace industry are discussed. The first rule is to select stable machining conditions and chatter must be completely avoided. Thin monolithic components can be made using conventional equipment. However, as spindle speed increases, the stable zones in the stability lobe diagram get larger, and higher metal-removal rates are possible. The second rule is to use a special machining strategy, which must be selected to cut the thick part, leaving the thin part. The third rule is to use relieved shank tooling for thin wall. Thinner and taller walls require deeper relief on the tool, smaller DOCs per pass and more passes.
