Effect of tool geometry variation on finish turning – A Review

The effect of cutting tool geometry has long been an issue in understanding mechanics of turning. Tool geometry has significantinfluence on chip formation, heat generation, tool wear, surface finish and surface integrity during turning. Thisarticle presents a survey on variation in tool geometry i.e. tool nose radius, rake angle, groove on the rake face, variable edgegeometry, wiper geometry and curvilinear edge tools and their effect on tool wear, surface roughness and surface integrityof the machined surface. Further modeling and simulation approaches on tool geometry including one approach developedin a recent study, on variable micro-geometry tools, is discussed in brief.
