Turning of steels at low depths of cut
Tichá, Dana ; Dvořáková, Jana (referee) ; Dvořák, Jaromír (advisor)
Thesis is devoted to the analysis of the competition of indexable cutting inserts, which are used for turning at lower cutting widths of the blade than the tip radius. Thesis is an analysis of five indexable cutting inserts from diferent companies. Furthermore the chip breakers of selected inserts are compared and finally the testing of the insert and its results based on metal chip shapes are described.

Influence of a size of a cutting edge rounding of the insert during turning
Tichá, Dana ; Sedlák, Josef (referee) ; Dvořák, Jaromír (advisor)
The work is focused on the durability test of replaceable cutting inserts, which are coated with a newly developed coating. In the work are tested two types of replaceable inserts with different shapers, while three different edge roundings are produced for each shaper. The test is performed on three different materials. During testing, the cutting depth doesn’t change, only the feed changes, where tests are performed on each material at two different feeds. A different cutting speed was chosen for each material and feed, which resulted in a durability of the replaceable insert cca 15–20 minutes. The goal of the work is to find out what is the most suitable rounding of the blade on replaceable cutting inserts, when applying a newly developed coating.
