Bezdotykové měření povrchových teplot při obrábění / Contactless measurement of surface temperatures when machining

Šťáva, Radek January 2008 (has links)
Contactless measuring of surface temperature integration in the other measurement methods and their assimilation at evaluation of surface temperature of a semi-finished product bored by various tools is the target of the work. An impassable opening is being bored by these tools. The opening is close to a scanned wall. The semi-finished wall temperatures are being scanned by thermocamera and subsequently compared for every single used tool in this experiment.

Vystružovací nástroje s břity z cermetu a PVD povlakem / Reamers with cermet cutting edge and PVD coating

Technik, Radim January 2009 (has links)
The Master’s thesis is focused on reaming technology using PVD coated reamers with cermet cutting edge. This work point out a historical evolution of reaming technology as well as recent requirements to the quality of produced surfaces. Reamers characteristic, splitting, mechanical designs, cutting tool geometry as well as the assumption of a reamer potential evolution are presented. Application of cermet tool material and PVD coatings to reaming tools is considered. The work contains a review of present statement at reamer market including cermet reamers and provided single cells (elements) of the Tool Management. The experimental part of the work is focused on product manufacture qualities verification of the changeable PVD coated reamer head made by HAM-FINAL ltd. Economic analysis in case of investment to the reamer purchase is demonstrated on the example of the practical application of the reamer.

Technologie výroby obráběním na CNC strojích / Technology of product machining on CNC machines

Brázda, Jiří January 2009 (has links)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.
