• Semester 6, position 3

1. Step-by-step perception of concepts and themes related to machine tools. 2. Acquisition of basic knowledge about machine tool primary motion configuration for cutting and deformation processing and configuration of feed motions. 3. Studies of machine tool structures, guides foundations and machine tools testing. 4. Studying and practicing the control and programming of numerically controlled machine tools and making a report on acquired knowledge.

Upon successful completion of this course students should be able to: 1. Choose environment of machine tools and prepare them for work for specific technological task. 2. Configure primary and feed motion of machine tools. 3. Plan and perform the experiment to test a machine tool and to identify the machining process. 4. Program numerically controlled machine tools. 5. Make selection concept of machine tools and their selection for a certain type of machining. 6. Prepare Technical elaborate and reports about testing and programming of machine tools.

New teaching contents: 1. Definition, classification and properties of machine tools. Configuration of machine tools. Learning resources. 2. The machine tools saga. 3. Work diagram of the primary motion of cutting machines and electromechanical drives for primary rotary motion. 4. Energy balance in machines for deformation processing. 5. Work diagram of feed motions in metal cutting machines. 6. Machine tools guides. 7. Electromechanical feed drives. 8. Machine tools testing. 9. Machine tools control and programming. Elaboration of new teaching contents and instructions for doing the tasks: 1. Work diagram of the primary motion. 2. Dimensioning of press energy accumulators. 3. Work diagram of feed motions. 4. Identification of machine tools guides. 5. Configuring of electromechanical feed drives.

Practical teaching consists of auditorial exercises, laboratory work, home work, seminar work and consultations. It embraces the following units: 1. One auditorial exercise: Resources for studying machine tools. 2. Four laboratory exercises: (1)Handling and manual operating of machine tools and handling of measuring equipment in the Laboratory for machine tools. (2)Identification of the main factors in deformation processing. (3)Machine tools testing. (4)Control and programming of machine tools. Instructions for work are given for each exercise, while forms and reports making are prepared beforehand. 3. Five home works. 4. One seminar work is done about control and programming of machine tools. 5. One consultation. A report on acquired knowledge of machine tools is prepared in parallel. Knowledge check comprises: two tests, three colloquiums and final examination.

Study curriculum and student motivation for learning about machine tools and machining systems according to the goals set and outcomes offered.
