The course of metal cutting machine tool design is a compulsory course in the manufacturing direction of mechanical specialty in our university. Under the background of engineering education accreditation, the course has been reformed. The new syllabus corresponding to the index points of graduation requirements was established, the teaching contents were integrated and optimized, project teaching method and diversified assessment method were designed, the evaluation method of course objectives achievement was constructed, the closed-loop course quality assurance system of Design-Implementation-Assessment-Evaluation-Improvement was formed. Students’ learning initiative and the learning effect are improved.

Metal Machining

In the practice of processing of metals by cutting it is necessary to overcome the vibration of the cutting tool, the processed detail and units of the machine tool. These vibrations in many cases are an obstacle to increase the productivity and quality of treatment of details on metal-cutting machine tools. Vibration at cutting of metals is a very diverse phenomenon due to both it’s nature and the form of oscillatory motion. The most general classification of vibrations at cutting is a division them into forced vibration and autovibrations. The most difficult to remove and poorly investigated are the autovibrations, i.e. vibrations arising at the absence of external periodic forces. The autovibrations, stipulated by the process of cutting on metalcutting machine are of two types: the low-frequency autovibrations and high-frequency autovibrations. When the low-frequency autovibration there appear, the cutting process ought to be terminated and the cause of the vibrations eliminated. Otherwise, there is a danger of a break of both machine and tool. In the case of high-frequency vibration the machine operates apparently quiently, but the processed surface feature small-sized roughness. The frequency of autovibrations can reach 5000 Hz and more.
