Course objectives:
Introduction to design and manufacturing for all kinds of: cutting tools (standard and special), devices, dies and special tools for fabrication previous mentioned tools. Introduce the students to designing tools for plastic deformation (forging, deep drawing) and moulds for polymers.
Student responsibilities:
Grading and evaluation of student work over the course of instruction and at a final exam:
Student is evaluated through regularity in the performance of assigned duties. Student can approach to two colloquium or to the final exam. At the colloquium as well as at the final exam, student have to show that he has defeated at least 52% of the total lecture content.
Methods of monitoring quality that ensure acquisition of exit competences:
Recording of attending lectures and active participation of students in discussions during lectures. Continuous monitoring of consultations during learning.
Upon successful completion of the course, students will be able to (learning outcomes):
after lecturing student will be able to: -estimate and design of cutting tools -estimate and design of devices -etimate and design a die cutter with destruction of material and without destruction of material - estimate and design of tools for polymer processing -estimate and evaluate various tools and devices for a particular technological process
