Data selection and optimisation of cutting conditions for progressive production technologies
Krupka, Ondřej ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
This thesis contains theoretical analysis of optimization methods of cutting conditions for current machining processes with focus on finishing turning. Further focus was put on influences of cutting conditions and other effects on requested quality and roughness of machined surface. The effect of part of these conditions was verified in experimental part. The influence of feed rate and depth of cut on surface roughness and geometrical accuracy was experimentally verified.
Reamers with cermet cutting edge and PVD coating
Technik, Radim ; Humár, Anton (referee) ; Kouřil, Karel (advisor)
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.
Application reamers with cermet cutting edge and PVD rating
Lučaník, Aleš ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
The introductory part of this bachelor´s thesis provides definitions of basic accuracy parameters, quality of machined surface and requirements on accu- racy of holes. Further work describe the current technical level of available reaming tools of global manufacturers in terms of technological aspects, tool materials, tool geometry and the main structural elements. The final part deals with designing, implementing and evaluating an experimental verification of usable properties of prototypes newly developed reaming tools in collaboration with the company HAM-FINAL.
Application reamers with cermet cutting edge
Toman, Martin ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
This thesis deals with the technology of reaming aimed mainly on cermet reamers. In the introduction of the thesis, the basic parameters of precision, dimension tolerance, geometrical tolerance and surface roughness are shown. Also, the technology of reaming, parameters, geometry and sorting of the reaming tools is analyzed in depth. The overview of the world producers of reaming tools is also shown as a supplement. In the final part, an example of production optimization by replacing a reamer with a better performing one is shown. Experimental part of this thesis has been made in the cooperation with HAM-FINAL company.
