Mechanical engineering services include construction, design, and repair. Companies specialize in metal components, manufacturing systems, and advice on construction projects. Mechanical engineers use computer-aided design tools in various fields. On-site repair services include salvages, machining, and alignment. The profession is regulated and requires proper training. Coursework includes thermodynamics, fluid dynamics, machine tools, and math classes.
Mechanical engineering services fall into three broad categories: construction, design, and repair. Some companies specialize in mechanical engineering projects of metal components and/or manufacturing systems and processes. Other companies provide repair services that are usually onsite to reduce costs and downtime to their customers’ facilities. Still other mechanical engineering service providers provide advice on construction projects as well as the design and installation of mechanical systems in everything from light commercial to large industrial facilities. This field is usually highly regulated to promote the safety and interests of the general public.
The design and build assistance offered by mechanical engineering service firms can involve entire engines, power plants, manufacturing assembly lines, and all-purpose, all-size vehicles. Projects often include an analysis of all types of mechanical systems and machine tool designs. Mechanical engineers usually use computer-aided engineering design tools in robotics, aerospace, petroleum engineering, chemical engineering, and medical device manufacturing. Mechanical engineering service firms that help build structures often need to perform structure analysis to determine material stresses, as well as custom design work for manufacturing process facilities and plants.
On-site repair mechanical engineering services can include salvages of industrial shafts that avoid the expense of removal, on-site machining, and cold repair of cast iron and other metal components. In addition, heat spraying the metal of industrial tolerance components can help replenish heat shielding surfaces, repairs can be made to worn propulsion components, and line drilling can be performed. Laser alignment services offered by repair companies can align rotating equipment to protect it from vibration and excessive bearing wear. Specialists in all types of metallurgy, steam and diesel mechanics and many forms of welding are often required in such firms.
The mechanical engineering profession is regulated by jurisdictions around the world with a view to licensing only those with the proper training. Standards are stringent in many areas. Most governments consider engineering a profession that requires a license before services can be offered to the public.
Individuals interested in becoming a mechanical engineer and providing mechanical engineering services are usually required to complete the appropriate coursework at an accredited engineering school or in distance learning online courses. Offerings include basics in thermodynamics, fluid dynamics and mechanics, machine tools and manufacturing engineering technologies. Additionally, mechatronic instrumentation, pneumatics, control theory, and materials engineering are some of the required courses. Math classes are required, including calculus, differential equations, linear algebra, and differential geometry, among others.
