I- WORKSHOP INTERNSHIP
Mechanical workshop internship is given to the students of Mechanical Engineering Department who have completed the first year. In order to participate in the internship, the qualification requirement is to have a passing grade from ME 182 Engineering Drawing and Solid Modeling course. Internship consists of the following three parts:
- Use of measuring and control instruments
- Use of Hand Tools
- Use of machine tools
Descriptions
The duration of the internship is three days. The students will attend the workshop in groups of three. Internship periods will be during the summer and winter breaks. Students wishing to apply for internship will first have to write their names to the department secretariat. The students will also fill in the WORKSHOP INTERNSHIP FORM (FORM 403) on the department website and have their advisors sign it. At the beginning of the internship, they will show this form to the Workshop Chief and after the completion of the internship, they will fill in the required parts and submit it to the Workshop Chief. Some instruments to be used by the student during the internship must be provided by the student before starting the internship. These are:
- Workshop apron
- 1/20 (0.05 mm precision) caliper (no high quality required)
- File of the leveler. 25 cm tall (10 fingers)

g) - Environmental policy of the firm or enterprise and use of recycled materials
h) - Marketing activities
i) - Occupational safety and employee-employer relations
j) - Personnel and social relations:
- Recruitment and training of staff
- Business valuation and wage policies
- Social Relations: The scope and aims of food, local, sports facilities, service, nursery and similar activities.
II.B Manufacturing and Assembly: Machining, non-machining manufacturing methods used in the plant to be examined and learned, following the production techniques to be practiced, semi-finished, finished product assembly, quality control processing and realization.
SUBTRACTIVE MANUFACTURING METHODS
In subtractive machining methods, the raw material is shaped by removing material called chip. Turning, Milling, Planing-Grinding, Drilling and Grinding are easas as 5 chip removal methods. In addition, there are very fine stock removal processes such as Honing, Fine Honing and Lapping, which are used to improve surface quality.
TURNING: In turning, the part makes the cutting motion and tool advance motion in the form of rotation. Turning, ie cylindrical (internal and external), conical parts, their front surfaces are machined and screwed. Internship scope: Recognition of lathe, operation, maintenance and security measures, connecting work to the machine, lathe pens, lathe cutting speed, lathe, surface, hole and screw pulling operations. all turning operations and drawings of manufacturing drawings, and recognition of the types of lathes.
MILLING: The tool rotates in the form of cutting and workpiece moves. With milling, any flat, curved planar surface, groove, T groove, screw, gear and other profiled elements are machined. Internship scope: Recognition, operation, maintenance and safety measures of the milling machine, connection of works to the machine, types of cutters and connection of the machine tools, milling cutting speed, feed rate and cooling, splitting in milling, milling machine grooving applications, milling of gear and cutters and the like milling operations and milling machine types.
PLANING-VARGING: In planing-varging, the cutting movement is linear, in varging, this movement is performed by the tool and planing by the part. Flat surfaces, grooves, gears and other profiled elements are machined with planing and varnishing. Internship scope: Working principles of planing and Vargel machines, definition of items, work safety in these machines, linking of works to the machine, calculation of cutting speed and number of courses, grooving in barrel and machining of various surfaces.
GRINDING: In grinding, the cutting movement is made by the tool and the feed movement by the workpiece. Grinding is a process that is made after other processes and mostly focuses on the size, shape and surface quality of the parts. By grinding, cylindrical (internal and external), conical, flat and curved planar surfaces, screws, gears and other profiled elements are machined. Internship scope: Grinding stone, safe working rules on grinding machines, bonding, grinding and balancing of grinding wheels, recognition of grinding machines, maintenance work and working rules of grinding machines, and simple grinding applications.
PUNCHING: The part is fixed and the tool performs both cutting and feed motion in the form of rotation. Drilling is done with cylindrical and conical holes. Scope of work: Hole benches, work done by benches, working principles and properties, and related applications.
In addition to the machines that use the 5 basic chip removal methods mentioned above, studies related to Hand Leveling and Other Benches, which are briefly mentioned below, can also be performed within the scope of this internship.
HAND LEVELING: Internship scope: Introduction and use of leveler hand tools and measuring instruments, filing, marking, cutting and drilling operations and guiding applications.
OTHER BENCHES: The works related to the existing machines but not explained above are included in the scope of this internship. Internship scope: Numerically Controlled Benches (NC), Computer Aided Numerical Controlled Benches (CNC) and Computer Directly Controlled Benches (DNC) etc. to have information about and make work on these stalls.
ADDITIVE MANUFACTURING METHODS
In chipless manufacturing methods, the raw material is shaped without removing material. Chipless manufacturing methods; mainly by casting, plastic deformation and bonding (welding, soldering, bonding, riveting).
CASTING: Casting is the process of shaping the pieces by pouring the material in the liquid or viscous state into a mold prepared or having a cavity representing the shape of the part and allowing it to solidify. Foundry, Casting Molding and Melting Technique can be grouped under two groups. Internship scope: general casting information, furnaces used in foundry, capacity and efficiency, foundry tools and tools (mold, core, model, mold sand and binders used, etc.), molding methods, pouring of molten metal into mold, evaluation of post-casting processes and production drawings drawing, casting types (cast iron, steel casting, alloy casting), and to be considered in the casting process.
PLASTIC SHAPING: In plastic forming, the desired shape is given by making a certain pressure on the raw material. Here, the material is brought into a permanent deformation state by means of printing and the shape given is permanent. The process is done cold and hot. Plastic forming involves processes such as Forging, Rolling, and Sheet Metal Processing.
- Forging: In the forging, the raw material heated to a certain temperature is shaped by applying impact or continuous pressure. Internship scope: Forging types, open forging, closed forging, forging tools and materials, press and mold works, press types, operation, maintenance and safety measures, technology and applications of press bending, bending, cutting and punching molds, introduction of mold types, mold technology and mold materials.
- Rolling: Rolling is the process of shaping the raw material by passing it between two rolls rotating around its own axes. The process can be done hot or cold. Internship scope: Rolling types, roller types, wire drawing and pipe rolling processes, rolling applications.
- Sheet Processing: Sheet and bands; cutting, bending, deep drawing, plastering, blowing processes such as forming processes. Internship scope: Separation and perforation (punching), punch types, cutting dies, bending types, deep drawing operations, plastering operations, plastering bars or rolls, plastering gauges, blowing and stretching operations, extrusion and cold pressing operations.
BINDING: Binding method parts are manufactured by other methods and then joined together to form a whole. Binding methods; welding, riveting, soldering and bonding. Welding: Welding is the method of connecting the parts to each other by means of heat and with or without additional material. Internship scope: Welding techniques and technological knowledge, recognition and use of welding tools and tools, oxygen and spot welding applications, electric arc welding and applications, other welding techniques and applications (submerged and submerged arc welding).
