Study track: Conception of Machines The study track "Conception of Machines" prepares students to develop and apply modern computer-aided methods focusing on the construction and dimensioning of structures and mechanical engineering systems according to functional requirements. The core compulsory courses for this area of specialisation include the fundamentals of structural mechanics, computational analysis, finite element methods and computer-aided design.

In addition to the compulsory courses, students choose various elective courses. Study track: Production of Machines The study specialisation "Production of Machines" prepares students to develop and use computer-aided systems in modern industrial production, which includes manufacturing technology, production systems, and production management. The programme takes place in Aachen Germany. A mandatory industrial internship of nine weeks has to be completed within the study programme. Lecturers upload learning materials onto the Moodle online platform so that students can use them before or after the lectures.

Some professors also record their own lectures to share with students. One of the following certificates must be submitted:. Generally, students enrolled at RWTH Aachen University have the opportunity to find a job on campus and work up to 19 hours per week. This also allows students to become more familiar with the university institutes and to take part in projects related to their field of study. The maximum working limit for off-campus work is days per year for non-EU students.

The staff of RWTH International Academy offers support in finding accommodation either in a student residence, in a private apartment, or in a shared flat. However, there are usually waiting lists for these rooms, and students will probably need to find private accommodation first. There are a number of options for finding private accommodation in and around Aachen, and RWTH International Academy can provide students with information beforehand and upon arrival.

For short-term accommodation, there are many hotels and two youth hostels. Our Career Services offer support for students looking for internships or full-time employment. Furthermore, we organise excursions to companies and factories regularly so that our students gain first-hand insight into the industry. Our graduates have overwhelmingly positive prospects, as on average they:. Currently, more than 44, students are enrolled in academic programmes.

More than 8, of them are international students hailing from different countries. As a result, our graduates are highly sought after by businesses to work as trainees and fill executive positions. National and international rankings show that our graduates have a high aptitude for managing complex tasks, constructively solving problems in teams, and taking on leadership responsibilities. Work conducted in the research centres at RWTH Aachen University is strongly oriented towards the current needs of industry, commerce, and the professions.

This has resulted in numerous innovations, patents, and licences. The problems are solved with the help of computer program. Manufacturing Control Another category of CAM application is development of computer supported system for implementing the manufacturing control functions. These control functions manage and control the physical operation in the factory. The applications of the process control are absorbed in automated production system. Which includes the example cases like transfer line assembly system, NC, robotics, material handling and flexible manufacturing systems.

All these will be discussed later on. Process monitoring and the control functions are deployed to regulate the actions of various production equipments. Some of the well known control systems used in the industry are as follows. Quality Control There are varieties of approaches that insure highest possible quality level in the manufacturing system and products and these are included in quality control. Shop floor control and computerized factory data collection systems are discussed in detail later on.

Inventory Control The important thing about inventory control is that it maintains the most appropriate level of inventory in the face of two opposing objectives: minimizing the investment and storage cost of holding inventory and maximizing service to customer. Just in Time Production System A production system that is planned to deliver exactly the right number of each component to downstream workstations in the manufacturing sequence just at the time when that component is needed is known as just in time production system.

This term is applicable to production operation and supplier delivery operation. Engineering activities in design include product design, engineering analysis and drafting whereas the process planning and NC part programming come in the manufacturing functions. The literal meaning of CAM is the manufacturing of the products with the aid of computers.

Manufacturing is defined as a chain of interrelated activities that comprises designing, material selection, planning, production, quality assurance, management and marketing of discrete consumer and durable goods. CAM includes these aforementioned manufacturing functions. Functions Operations Planning Mfg. Control Figure 1. The conventional method of manufacturing a product which involves two separate procedures — designing the product and process planning — is a time consuming one and also involved duplication of effort by design and manufacturing personnel.

On a numerically controlled machine tool, a large portion of the processing can be completed. CIM system includes the application of computer and communication technologies to all of the operational functions and information processing functions starting from the order receipt through design and production to product delivery. Computer system touches all the activities throughout the firm that support manufacturing.

Product design department takes these specifications as the input. Manufacturing engineering takes its input from the output of the design department where process planning, tool design, and similar activities are supported by the CIM system. CAPP performs process planning. On a CAD system, using the product model which is generated during product design, tool and fixture design is done.

Manufacturing engineering provides its output into production planning and control, where material requirements planning and scheduling are performed using the computer system. Differentiate them. Discuss each type in detail. This information is sent to the potential supplier for further studies. Then, supplier evaluates the tooling, fixturing and other requirements of the given drawing and asses its manufacturing suitability keeping in view its production and other technological features.

The completed designs having such details are sent again to the manufacturer by the supplier. Adopting the simulation and other optimization tool, manufacturer transfers the drawing to the dedicated CAD system. One more cycle of drawing are reverted back to the supplier, where moderation incorporated by the manufacturer is included. At this stage, supplier also includes some of the changes according to the suggestion furnished by the manufacturer. Detail control cycle of the design transferred to illustrate the mechanism of CAD system is described in Figure 1. It happens due to the fact that supplier of the computer application may develop the design configuration for different priory format to store the data required and its display.

In order to ensure the compatibility for smooth data sharing, there is a need of neutral data exchange format. Here the term neutral refers to a format that can be easily exploited by various systems. Reasonably good data exchange format or standard or neutral file should satisfy a minimum set of requirement.

These requirements are concerned with the common entities needed in different modeling system such as wire frame entity and surface entity etc. It is expected from a standard format that it should become compact and help in achieving faster data storage and retrieval. In the s, the features of IGES were published and in subsequent years the same has been thoroughly updated.

The same format has also been adopted to communicate the data among the manufacturer and the suppliers.

Therefore, it can be inferred that IGES helps to develop a communication interface among the different system. It refers to global standardization of exchange of information pertaining to the computer application in manufacturing. Features of STEP have been utilized to evolve another data exchange standard known as product data exchange,which has found wide ranging application for different type of work in the industry.

These are : 1 application layer, 2 logical layer, and 3 physical layer. The user and PDES are interfaced by the application layer, where application model is clearly defined and different types of information is expressed using information modeling techniques. The main task of logical layer is to support faultless, consistent and computer independent description so that sufficient information is available to encapsulate the wide range of applications.

In order to maintain the structure and format of exchange file, the role of physical layer comes into picture to efficiently manage the magnitude of the file sizes. This format is capable of implementing features of AutoCAD and also converts them into file representation. Irrespective of data exchange systems, the common way through which drawing details are transferred electronically among the different CAD system are explained in Figures 1. Adequate attention has been focused in this unit about various component related to CIM.

Where it is explained that CIM is a process of using computers and communications network to transform island of enabling technologies into a highly interconnected manufacturing system. Details pertaining to enterprise wide integrating and CIM wheel are included in this unit to provide glimpses about the wider capacity of underlined subject. After going through the content of this unit, one can easily comprehend the importance of CIM in enhancing the productivity for different types of production system.

Computer Aided Design : Computer aided design denotes the use of the computer systems to support the product design system. Computer Aided : The term denotes the pervasive use of computer system Manufacturing to design the product, to plan the production, control the operation and perform the business related functions needed in the manufacturing firm.
