Study Notes
Machine Tools
- A machine tool is a power-driven machine used for cutting, shaping, and finishing metal or other rigid materials.
- Modern machine tools are computer numerically controlled (CNC).
Types of Machine Tools
- Machine tools can be classified into six groups: drilling and boring, grinding, turning, shaping and broaching, metal forming, and milling.
Lathe Machine
- A lathe rotates the workpiece on its axis to perform various operations.
- A lathe consists of a stand, lathe bed (horizontal beam), headstock, and tailstock.
- The headstock contains high-precision spinning bearings and a rotating horizontal axle (spindle) that is parallel to the bed.
- The spindle is powered and imparts motion to the workpiece.
- The power source is usually an integral electric motor.
Turning and Drilling
- Turning is a form of material removal process used to create rotational parts by cutting away unwanted material.
- Drilling is the process of cutting holes in a solid material using a rotating cutting tool.
CNC Machines
- A toolpath is a series of instructions that define the movement of a cutting tool on a CNC machine.
Applications of Machine Tools
- Machine tools make the working parts of various products, including telephones, television sets, radios, washing machines, refrigerators, and automobiles.
