Chapter 13 provides comprehensive knowledge regarding machinability of construction materials and characterizes various meanings of this specific material feature, allowing effective selection of machining conditions. Factors affecting machinability and typical causes of low machinability are discussed. Three groups of machinability criteria are selected, including basic, substitutive and auxiliary ones. In particular, the cutting speed corresponding to economic or high productivity criteria and obtainable surface roughness are distinguished as basic machinability criteria. Relative and absolute machining rating systems are highlighted, and appropriate material groups and values of the machining rating for typical construction materials are provided. Six ISO material groups (including unalloyed steels, alloyed steels, stainless steels, cast irons, titanium alloys, HRSA materials, lightweight materials, composite materials and refractory metals) are characterized in terms of machinability rating. Practical recommendations concerning its improvement by means of proper selection of cutting tool materials, machining conditions and machining best practices are given.
