ECTS Credit Points: 4
Evaluation: mid-semester grade
Year, Semester: 2nd year, 2nd semester
Its prerequisite(s): Aircraft Technology
Further courses are built on it: Yes/No
Number of teaching hours/week (lecture + practice): 2+2
Topics:
During this semester the students learn the types of cutting machines, devices and tools. The students will know the types of basic cutting technologies (turning, drilling, milling, planning, grinding, etc.) and their characteristics. Introduction of the basic industrial design- and operation documentation procedure in manufacturing. Primary forming processes (casting, powder metallurgy, metallurgical, hot forming processes). After that the students will learn designing basic manufacturing tasks and calculating the necessary technological parameters for a given workpiece.

Requirements
A, for a signature:
Students have to visit the lectures and seminars. Three absences are acceptable during the seminar. Students have to write two tests from the two parts of the lectures and seminars (cutting technologies and metal forming technologies). They have to write them for minimum at a sufficient level. Based on these result they will get the final practice mark.
B, for a grade:
The course ends in mid-semester grade. Based on the average of the marks of the planning task and the average of the test results, the mid-semester grade is calculated as an average of them:
- grade of the planning task
- average grade of the two tests
The minimum requirement for the mid-term and end-term tests is 60%. Based on the score of the tests separately, the grade for the tests is given according to the following table:
0 - 59 % = fail (1); 60 – 69 % = pass (2); 70 - 79 % = satisfactory (3); 80 - 89 % = good (4); 90 - 100 % = excellent (5)
If the score of any test is below 60, a student once can take a retake test covering the whole semester material.
