Outside the factory, robots have been employed in bomb disposal, space exploration, and many other fields. Robots are also sold for various residential applications. These systems may include material handling equipment, machine tools, robots or even computers or networks of computers. Manufacturing engineers possess an associate's or bachelor's degree in engineering with a major in manufacturing engineering. The length of study for such a degree is usually two to five years followed by five more years of professional practice to qualify as a professional engineer.
Working as a manufacturing engineering technologist involves a more applications-oriented qualification path.
For manufacturing technologists the required degrees are Associate or Bachelor of Technology [B. Doctoral [PhD] or [DEng] level courses in manufacturing are also available depending on the university. The undergraduate degree curriculum generally includes courses in physics, mathematics, computer science, project management, and specific topics in mechanical and manufacturing engineering. Initially such topics cover most, if not all, of the subdisciplines of manufacturing engineering.
Students then choose to specialize in one or more subdisciplines towards the end of their degree work. This syllabus is closely related to Industrial Engineering and Mechanical Engineering, but it differs by placing more emphasis on Manufacturing Science or Production Science. It includes the following areas:. A degree in Manufacturing Engineering typically differs from Mechanical Engineering in only a few specialized classes. Mechanical Engineering degrees focus more on the product design process and on complex products which requires more mathematical expertise.
In some countries, "professional engineer" is the term for registered or licensed engineers who are permitted to offer their professional services directly to the public. In order to qualify for this license, a candidate needs a bachelor's degree from an ABET recognized university in the USA, a passing score on a state examination, and four years of work experience usually gained via a structured internship.
In the USA, more recent graduates have the option of dividing this licensure process into two segments.
The Fundamentals of Engineering FE exam is often taken immediately after graduation and the Principles and Practice of Engineering exam is taken after four years of working in a chosen engineering field. The SME administers qualifications specifically for the manufacturing industry.
These are not degree level qualifications and are not recognized at the professional engineering level. The following discussion deals with qualifications in the USA only.

Qualified candidates for the Certified Manufacturing Technologist Certificate CMfgT must pass a three-hour, question multiple-choice exam. The exam covers math, manufacturing processes, manufacturing management, automation, and related subjects. Additionally, a candidate must have at least four years of combined education and manufacturing-related work experience. Candidates qualifying for a Certified Manufacturing Engineer credential must pass a four-hour, question multiple-choice exam which covers more in-depth topics than does the CMfgT exam.
CMfgE candidates must also have eight years of combined education and manufacturing-related work experience, with a minimum of four years of work experience. The Certified Engineering Manager Certificate is also designed for engineers with eight years of combined education and manufacturing experience. The test is four hours long and has multiple-choice questions. The CEM certification exam covers business processes, teamwork, responsibility, and other management-related categories. Many manufacturing companies, especially those in industrialized nations, have begun to incorporate computer-aided engineering CAE programs into their existing design and analysis processes, including 2D and 3D solid modeling computer-aided design CAD.
This method has many benefits, including easier and more exhaustive visualization of products, the ability to create virtual assemblies of parts, and ease of use in designing mating interfaces and tolerances. Other CAE programs commonly used by product manufacturers include product life cycle management PLM tools and analysis tools used to perform complex simulations.
Analysis tools may be used to predict product response to expected loads, including fatigue life and manufacturability. Using CAE programs, a mechanical design team can quickly and cheaply iterate the design process to develop a product that better meets cost, performance, and other constraints. No physical prototype need be created until the design nears completion, allowing hundreds or thousands of designs to be evaluated, instead of relatively few.

In addition, CAE analysis programs can model complicated physical phenomena which cannot be solved by hand, such as viscoelasticity, complex contact between mating parts, or non-Newtonian flows. Just as manufacturing engineering is linked with other disciplines, such as mechatronics, multidisciplinary design optimization MDO is also being used with other CAE programs to automate and improve the iterative design process.
MDO tools wrap around existing CAE processes, allowing product evaluation to continue even after the analyst goes home for the day. They also utilize sophisticated optimization algorithms to more intelligently explore possible designs, often finding better, innovative solutions to difficult multidisciplinary design problems. Manufacturing engineering is an extremely important discipline worldwide. It goes by different names in different countries.
Mechanics, in the most general sense, is the study of forces and their effects on matter. Typically, engineering mechanics is used to analyze and predict the acceleration and deformation both elastic and plastic of objects under known forces also called loads or stresses. Subdisciplines of mechanics include:. If the engineering project were to design a vehicle, statics might be employed to design the frame of the vehicle in order to evaluate where the stresses will be most intense.
Dynamics might be used when designing the car's engine to evaluate the forces in the pistons and cams as the engine cycles. Mechanics of materials might be used to choose appropriate materials for the manufacture of the frame and engine. Fluid mechanics might be used to design a ventilation system for the vehicle or to design the intake system for the engine. Kinematics is the study of the motion of bodies objects and systems groups of objects , while ignoring the forces that cause the motion.
The movement of a crane and the oscillations of a piston in an engine are both simple kinematic systems. The crane is a type of open kinematic chain, while the piston is part of a closed four-bar linkage. Engineers typically use kinematics in the design and analysis of mechanisms. Kinematics can be used to find the possible range of motion for a given mechanism, or, working in reverse, can be used to design a mechanism that has a desired range of motion. Drafting or technical drawing is the means by which manufacturers create instructions for manufacturing parts.
A technical drawing can be a computer model or hand-drawn schematic showing all the dimensions necessary to manufacture a part, as well as assembly notes, a list of required materials, and other pertinent information. S engineer or skilled worker who creates technical drawings may be referred to as a drafter or draftsman. Drafting has historically been a two-dimensional process, but computer-aided design CAD programs now allow the designer to create in three dimensions.
Optionally, an engineer may also manually manufacture a part using the technical drawings, but this is becoming an increasing rarity with the advent of computer numerically controlled CNC manufacturing. Engineers primarily manufacture parts manually in the areas of applied spray coatings, finishes, and other processes that cannot economically or practically be done by a machine. Drafting is used in nearly every subdiscipline of mechanical and manufacturing engineering, and by many other branches of engineering and architecture.
Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Metal fabrication is the building of metal structures by cutting, bending, and assembling processes. Computer-integrated manufacturing CIM is the manufacturing approach of using computers to control the entire production process. Computer-integrated manufacturing is used in automotive, aviation, space, and ship building industries.
Mechatronics is an engineering discipline that deals with the convergence of electrical, mechanical and manufacturing systems. Such combined systems are known as electromechanical systems and are widespread. Examples include automated manufacturing systems, heating, ventilation and air-conditioning systems, and various aircraft and automobile subsystems. The term mechatronics is typically used to refer to macroscopic systems, but futurists have predicted the emergence of very small electromechanical devices.
Already such small devices, known as Microelectromechanical systems MEMS , are used in automobiles to initiate the deployment of airbags, in digital projectors to create sharper images, and in inkjet printers to create nozzles for high-definition printing. In future it is hoped that such devices will be used in tiny implantable medical devices and to improve optical communication. Textile engineering courses deal with the application of scientific and engineering principles to the design and control of all aspects of fiber, textile, and apparel processes, products, and machinery.
These include natural and man-made materials, interaction of materials with machines, safety and health, energy conservation, and waste and pollution control. Additionally, students are given experience in plant design and layout, machine and wet process design and improvement, and designing and creating textile products.
Throughout the textile engineering curriculum, students take classes from other engineering and disciplines including: mechanical, chemical, materials and industrial engineering. Advanced composite materials engineering ACMs are also known as advanced polymer matrix composites. These are generally characterized or determined by unusually high strength fibres with unusually high stiffness, or modulus of elasticity characteristics, compared to other materials, while bound together by weaker matrices.
Advanced composite materials have broad, proven applications, in the aircraft, aerospace, and sports equipment sectors. Even more specifically ACMs are very attractive for aircraft and aerospace structural parts. Manufacturing ACMs is a multibillion-dollar industry worldwide. Composite products range from skateboards to components of the space shuttle.
The industry can be generally divided into two basic segments, industrial composites and advanced composites. Certain products have long interdisciplinary design actions in different development cycle times. Examples are aircraft and engineering domains in addition to consequent automobiles.

Introduction II. CAD is the use of computer technology production system.
Integrated Computer-Aided Manufacturing
It contributes more than any for design and design documentation. CAM software uses the models fit for use in making products over the long term. This may mean identifying some deficiency manufacturing does not stop the goal to automate in a current machine design by an engineer, or certain stages of the design and manufacturing but perceiving some new product opportunity by a also to automate the transmission of data, these salesperson.
