Machining is a powerful tool in modern engineering. Below, discover the definition of machining, and how it stands in the industry today. You will also explore the differing stages and applications of the concept as it pertains to contemporary infrastructure, projects and outcomes.
What Is The Definition of Machining?
Machining is a manufacturing process where a shape is created by removing excess material from a larger piece. This is usually employed when making finished products, as well as for raw material processing. Subtractive manufacturing is another, alternate term commonly used to describe machining processes. Machining often requires the use of complex parts, which call for multiple machining processes working in harmony with one another. The conjunction process is often found in the creation of large-scale infrastructure. To achieve high levels of accuracy, many machining processes have a high level of control over the material removal and shaping processes. Materials used in machining processes span from metals to wood, glass plastics, ceramics and many more, as almost all common materials will support the discipline.
Machining processes use a machine tool to create shapes from larger raw materials. These modern tools are often automated, using inbuilt computing systems to interpret commands and create the desired shape on the part in question. The types of technologies used to create these shapes can vary, and the method of the given commands will depend on the technological system chosen. Many modern machining tools will use CAM programming.
The Stages of Machining
Machining processes are complex operations, and they go through many different stages to complete part production. These different stages include:
Design: For automated manufacturing using CAM programming, a graphic design of the part is created. This is saved as a Computer Aided Design (or CAD) file. This may not be the case in the production of minor adjustments and manual machining tasks.
CAM File Creation: CAM files contain code that a machine can read, digest and understand. This is referred to as the G-code. This converts the CAD file to a CAM version so that it can proceed to the setup processes. Machines that do not use CNC do not use the CAM file.
Setup: All machines require setup before processes can begin and subsequently be executed. This includes loading a workpiece, aligning the settings and checking connections.
Machining: After the setup, the machine will execute the machining process, this is done under the surveillance of the operator.
Unloading: Once completed, the product is removed from the machine and sent for assembly.
Machining Applications
Some industrial applications of machining processes include:
Mining and Mineral Processing: Machinery used throughout the mining and mineral refinery processes such as valves and pumps.
Aerospace: Planes and flying machines as well as drones utilise machining to create high-quality, long-lasting equipment.
Automotive: Many parts used in the automotive industry require the precision and advanced production capacity of machining. This includes vital automotive components such as engines, steering systems and transition systems.
