After successful completion of the course, students are able to:

• describe geometrical and kinematic aspects and cutting force components of machining processes
• calculate cutting force and power requirement
• state characteristic attributes of cutting materials and coatings
• explain tool wear mechanisms and wear size
• explain advantages and disadvanteges of cooling lubrication, dry machining and minimum lubrication
• explain basics of high speed cutting and micro machining
• understand basics of forming and characteristic forming parameters
• calculate selected forming processes

Machining:

• technical sufaces, tolerances and requirements for machining operations
• geometrical and kinematic aspects of machining processes
• forces due to cutting processes
• chiping process by standard and high speed machining processes
• specific cutting force and their determination
• properties and application of cutting tool materials and coatings
• mechanisms of tool wear, durability of cutting tools
• coolant, dry machining, minimum quantity lubrication
• high speed cutting (basics and application)
• micro machining application

 Forming:

• basics in forming technology (plastic deformation, strain hardening, recrystallisation annealing)
• characteristic parameters of forming technology (forming degree, forming speed, temperature, yield stress, tensile strength, elongation at fracture)
• computational description (tension distribution, forming energy, efficiency)
• selected forming processes and sample calculations (bending, deep drawing, hydroforming, wire drawing, extrusion and forging)
• hybrid processes
• forming presses
• forming dies

The topics of the course will be introduced and explained in lectures, sample calculations will be demonstrated
