Course detail

Machining and Forming Theory and Tools

FSI-GTN-KAcad. year: 2011/2012

The course is divided into two parts: theory of machining plus tools, and theory of metal forming plus tools. In the first part, students gain the basic knowledge in the area of taking chips, machining methods and experimentally established relations in the theory of machining. The principles of designing cutting tools are discussed, as well as the optimization of the cutting process, the choice of cutting materials and their effect on the durability and service life of tools. In the second part the students acquire the basic knowledge of and skills in mathematically describing metal-forming processes while applying the physical, chemical, mechanical and thermodynamic principles of the transition of metallic bodies from elastic into plastic state in the course of their plastic deformation into the required shape. Within this subject the loading of the metal-forming tools is dealt with and provisions are made for a first design of the forming machine.

Learning outcomes of the course unit

The knowledge gained enables proposing a technological process of machining or metal-forming, together with the first design and determination of the dimensions of machining or metal-forming tools and the selection of necessary machines.

Prerequisites

Successful completion of the course is conditional on the knowledge of applied mathematics and physics, materials science, elasticity, strength, and plasticity, and a grasp of the machining and metal-forming technologies.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Conditions of awarding the course-unit credit: participation in exercises, working out the reports set, acceptance of the reports. In justified cases the teacher may set a make-up exercise program. The examination is public, testing the knowledge from both parts of the course, focused on machining and metal-forming.
