Factors Governing Shape of a Turn­ing Tool | Lathe | Industrial Engineering

Factors Governing the General Shape of a Turn­ing Tool and the Contour of its Cutting Edge: The most important points in any turning tool are: (a) The cutting edge of the tool must have a certain shape or contour. Some turning tools have straight rounded corners as at (i) (ii) and (iii) of Fig. 12.100, whereas others have curved edges [...]

Power Flow from Motor to Spindle: With Diagram | Lathe | Industrial Engineering

The power flows from the motor in the base to the cone-pulley by means of a belt. The belt can be adjusted to three or four positions to vary the spindle-speed. Fig. 12.15 gives the idea as to how the different spindle speeds can be obtained. Various spindle speeds can be obtained by shifting the belt on different steps of [...]

Preparation and Setting of Lathe | Machine Tools | Industrial Engineering

Setting is the preparation of the lathe for a specific operation according to the manufacturing process in order to ensure the required production rate, accuracy, and surface finish. After setting, two or three work parts are processed and checked, and if their size deviates from the values stated by the drawing, the tool position is corrected to obtain the required [...]

Chucking Work for Lathe | Machine Tools | Industrial Engineering

Work that cannot be readily mounted between the lathe centres is usually held in a chuck. Many machining operations can be performed on work held in a chuck, such as threading, boring, turning etc. Independent (4-jaw) chuck of lathe is used more than other types because it can hold practically any shape of work and can be adjusted to any [...]
