The manufacturing (or production) process of a factory, in a broad sense, is the sum total of separate processes involved in the conversion of raw materials or semi-finished products into final products. As far as a factory is concerned, its products can be blanks, finished parts, mechanisms, units or end products. The raw materials or semi-finished products used for manufacturing the products are often produced and supplied by other factories. Sometimes the products of the factory need to be further processed by other factories before they e

The manufacturing (production) process includes not only processes acting directly upon the manufactured objects, but also preparatory processes (such as production planning, process planning, production scheduling, tooling preparation, etc.) and auxiliary processes (such as equipment maintenance, inter-shop material and workpiece handling, cutting tool sharpening, quality inspection, production statistics, cost accounting, etc.)
The processes, acting directly upon the manufactured objects, change the shape, dimensions and properties of raw materials or semi-finished products, or assemble parts into final products. These processes are manufacturing (or production) processes in a narrow sense.

There are various manufacturing processes used for converting raw materials into finished parts. These processes include casting, forging, welding, punching, forming, machining, heat-treatment, plating, coating, and so on. Among them, the machining process plays an important role in the manufacture of parts.
The machining process of a part may include various machining operations, such as turning, milling, drilling, grinding, broaching, gear-cutting, etc. depending on the required sha
