WebMachinability is expressed in terms of a ‘machinability index’* for the material. • Multiple setups can be a source of variability. • Selection of appropriate cutting tool, coolant/lubricant, feed rate, depth of cut and cutting speed with respect to material to be machined is important. • Coolant also helps flush swarf from cutting area. • WebDec 13, 2013 · Compared to machining other metals, a larger percentage of the heat in a titanium machining process instead goes into the tool. Because of this effect, the choice of radial engagement dictates the choice of surface speed in this metal. The graph in Figure 1 shows this. Full slotting—meaning 180-degree engagement—demands a relatively low ...

WebOct 13, 2016 · In fact, due to its properties, titanium alloys are becoming more prevalent than ever before in structural and landing gear components. One drawback of these alloys is their poor mach inability... WebThe reference material for steels, AISI 1112 steel has an index of 1. For a tool life of 60 min, the AISI 1045 steel should be machined at 0.36 m/s. Hence, the machinability index for this steel is, KM = 0.36/0.5 = 0.72. This index is smaller than 1, therefore, AISI 1045 steel has a worse workability than AISI 1112. Machinability Rating. tatu - thai hoang
