Subject aims expressed by acquired skills and competences

After completing this course you will be able to actively use the physical fundamentals of machining for measuring important machining parameters such as cutting force, rustiness, machinability, heat and temperature, etc. Further processing then operate the new and modern production methods and gear you will be acquainted with the progressive methods of machining Such as HSC, HFCs and construction machinery and tools for these technologies.

Summary

Experimental and special machining methods Continuation of Theory of machining, design and production tools, design and manufacture of products and CAM systems in the machining experiments implementing practical measurement on machine tools designed for the purpose of measuring apparatuses and utilities. Students receive both theoretical interpretation of the individual tasks and their practical implementation in the laboratory department 346, including processing results in the form of programs. Include special methods of production gear and products, and multi-axis machining and vysokorychglostní.
