机械制造装备设计（Mechanical manufacturing equipment design） Test 1, short answer questions (3 points per day, a total of 12 points) 1. turret type combination machine tool can install several multi axle boxes on turret rotating worktable, and make each multi axle box turn to machining position in turn. The 2. form of broaching cutter tooth and the outline workpiece surface shape is similar to that of the cutting tooth height increasing back margin, the workpiece was a layer to cut off by the last cutter tooth cut out the required size calibrated tooth repair light reaches the predetermined broaching machining accuracy. 3. machine tool fixture, machine tool fixture is used in machining to determine the correct location of the workpiece, and make the workpiece fixed to withstand cutting force, easy to accept processing equipment. 4. the machine tool loading height refers to the vertical distance from the surface of the workpiece to the bottom of the machine. The 1. hole machining compound tool is processed by two or more individual holes, and the special cutter formed on the cutter body is called a hole cutting tool. The 2. fixture setting device enables the fixture to be positioned and fixed on the machine tool, that is to ensure that the fixture is in exact position and direction relative to the machine tool spindle (or tool) and the machine tool moving guide rail. 3. machine tool productivity machine tool productivity refers to the number of workpieces that the machine can process in unit time. 4. machine tools pre assembly machine tools, in order to compensate for tool wear or manufacturing and installation errors, power components can be adjusted forward distance. 1. the machine tool loading height refers to the vertical distance from the surface of the workpiece to the bottom of the machine. 2., the fixture positioning components can be installed workpiece, not only in the machine tool to determine the workpiece relative to the correct location of the tool parts. 3. gen
