Surface speed is the relative velocity between the rotating workpiece or cutting tool and the stationary counterpart, usually expressed in meters per minute or surface feet per minute. It directly influences cutting temperature, tool wear, and surface finish.
Tool life is the duration a cutting tool can effectively machine material before needing replacement or reconditioning. It is typically measured in minutes of cutting time or volume of material removed.
Cutting force is the total force exerted by the cutting tool on the workpiece during material removal. It is a vector quantity that influences power consumption, tool deflection, and vibration.
A powered mechanical device used to shape or machine metal or other rigid materials by removing material via cutting, grinding, or electrical discharge.
The glass transition temperature (Tg) is the temperature at which an amorphous polymer transitions from a hard, glassy state to a softer, rubbery state. It is a critical thermal property that affects mechanical behavior and processing conditions.
The cavity is the hollow space within a mold that shapes the molten plastic into the final product. It is the negative impression of the part.
Tempering is a heat treatment process where a quenched metal is reheated to a specific temperature below its critical point to reduce brittleness and relieve internal stresses. It improves toughness while maintaining adequate hardness.
The amount of thermal energy transferred to the workpiece per unit length of weld, typically expressed in joules per millimeter or kilojoules per inch.
A gas or gas mixture used in arc welding to protect the molten weld pool from atmospheric contamination by oxygen, nitrogen, and water vapor.
A machining operation in which a rotating workpiece is shaped by a single-point cutting tool that moves along or across the axis of rotation. It produces cylindrical, conical and grooved external surfaces on a lathe.
A machining operation in which a rotating multi-tooth cutter removes material from a workpiece that is fed past it in a controlled direction. It produces flat faces, slots, pockets, contours and gear teeth.
A machining operation that creates a round hole in a workpiece by feeding a rotating multi-point tool along its own axis. It is normally a roughing operation whose accuracy is later improved by reaming or boring.
An abrasive machining process in which a rotating wheel made of bonded abrasive grains removes very small chips from a workpiece. It is chosen for hard materials and for achieving tight tolerances and fine surface finishes.

A hard, wedge-shaped implement that shears material from a workpiece to form chips during a machining operation. Its material, geometry and coating determine the achievable cutting speed, surface finish and tool life.
The rate at which a cutting tool advances relative to the workpiece, expressed per revolution, per tooth or per minute. It largely governs chip thickness, cutting force, surface roughness and cycle time.
The relative surface velocity between the cutting edge and the workpiece, usually stated in metres per minute. It controls the temperature at the cutting zone and is therefore the dominant factor in tool life.
