Účel designu u ručního nářadí / The purpose of design for hand tools

Remeš, David January 2018 (has links)
This thesis deals with the effect of the design on hand tools. In the first theoretical part of this thesis, individual manual operations carried out during manufacturing are being further analyzed. The next part then focuses on the individual aspects of the product design and its influence on the hand tools. Followed by the processing of achieved parameters in handwork. The experimental part of this thesis deals with adjustments of the tap wrench´s handles made for manual cutting of internal threads. The utilization of the material when selecting a semi-finished product from blanks as well as the evaluation of the manufacturing in this way itself are also closely described in this part.

Zvyšování řezivosti maticových závitníků pomocí PVD povlaků / On the increase of cutting performance of thread cutting taps with PVD coatings

Samešová, Zina January 2012 (has links)
This thesis, in its theoretical part deals with the process of cutting, abrasion-resistant layers properties and their contribution to increasing of cutting properties. The second part of the thesis is experimental. It aims to determine, compare and subsequently evaluate cutting properties of threading tools using matrix taps with different types of PVD coatings. During implementation of the experiment, constant cutting conditions have been ensured and the only variable was the different types of coating layers. Outcome of the experiment is measurement of cutting torques in relation on time and rate of wear of cutting tools.
