Machining Technology
Machining technology is the application of sophisticated technology used to cut and shape materials such as metal, plastics and composites. This process is also known as machining and it is used to create precision components such as car parts, medical device components and aerospace components. This technology is highly complex, requiring proficient machines and well-trained machinists.
Machining is a manufacturing process in which a material is cut to a desired shape or size by using a specialized cutting tool, such as a drill bit, milling cutter, or even a laser beam. Machining typically involves one of two main processes: maintaining or shaping existing material (such as cutting or trimming) or removing material altogether (such as through drilling, milling, or grinding).
The machines used in machining are often classified based on their function. Generally speaking, there are two types: forming machines and cutting machines. Forming machines mould or shape material into a desired shape, while cutting machines create or alter existing material. The most common cutting machines used in industry are lathes, drill presses, and machining centers.
Lathes, also known as turning machines, are capable of rotating a material in a horizontal or vertical orientation. This allows the operator to shape the material by cutting away excess material. Many lathes are automated, meaning they are operated through a computer numerical control (CNC) system. This gives the operator greater accuracy and control when machining the material.
Drill presses are mainly used for drilling through material at specific points. These presses are equipped with a specialized drill head and drill bit, and normally vary in size. Machining centers are more advanced machines, capable of automated drilling and milling operations, as well as several other operations at a single station. These are mainly used on larger scale projects, but can be used to machine smaller components as well.
Machining is a very precise technology and requires a high level of expertise to successfully complete. Machinists must be able to read and interpret blueprints, use exact measurements and tolerances, and use computer programs to operate their machines. Furthermore, they must be able to identify potential problems and adjust the machine accordingly. Computerized machines are becoming increasingly prevalent in the machining industry, and machinists must know how to operate and monitor these machines.
The development of machining technology is ongoing and will continue to grow in scope and capability with developments in automation and computerization. Many students are looking towards a career in machining, as the field offers competitive salaries, opportunities for advancement, and job security. With a manufacturing background and the correct licensing and certifications, students can enter a career in machining and start building a successful career.
