Solution technology of two groove guide pulley production.
Šimonek, Ondřej ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Technology deals with the production of the two - groove guide pulley for two types of semiproducts. Technological process of production solves the production of the guide pulley from the first gripping of semiproduct to handing over of the guide pulley to the warehouse. Semiproducts are two types of castings with different separating plane. The material of the guide pulley is always gray - cast iron ČSN 42 2420. Production method is cutting operation with CNC machines. The production uses tools with interchangeable cutting tips. The aim of this work is to find the most optimal method of production from both time and economic perspective and to compare the two variants.

Cutting operation of cover parts.
Kobliha, Lukáš ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
In This thesis is elaborated a proposal for the manufacture of specified parts of the cover. The The work contains an analysis of components and analysis of possible technologies usable for the production, including concretely selected machines and tools. Elaborated is also a technological process, manual for to work on a lathe, and the theoretical number of units produced per year, depending on the shift working consumption indexable cutting inserts for turning.

Solution technology multiple groove guide pulley.
Teplý, Radek ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This essay discusses the production technology of multiple-grooved pulley and evaluates the technology of construction, the choice of the semi-product and their possible variations for production. The next aim is to describe the choice of production technologies, the selection of tools, the composition of technological process and the composition of different ways of chip removal during production. The essay also presents an economic of batch-production and it defines the optimal ways of production with regards to production costs.

Production of screw-thread in small engineering company.
Straka, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This work, wrought in branch of engineering technology in terms of baccalaureate studies, mentions the basic type partitioning of screw threads and their screw-threads labelling. There are presented some possibilities of screw threads manufacturing by chip-forming operation and by chipless machining operation, both with using of appropriate tools. Further the methods of production used in small machine-works are described. In this case the small machine-works is represented by secondary technical school.

Solution cutting operation of cover part.
Loukota, David ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Analysis of the typical flanged parts, constructional and functional appreciation of the single part, design of the semi-finished product and fastening of the semi-finished product, choice of machines, tools, gauges for individual operations and technological process design and time calculation of of individual operations. Economical appreciation deal with assesment of the number of machines and deal with their usage at the production, calculation of sizes process area and quantity of the workers. Final costs of tools are also solved.

Solution wear of tool with inserts in condition technology of turning.
Kružík, Petr ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis analyzes wear occurrence at chosen tool inserts in the process of turning of a heat treated cylindrical workpiece. Inserts for turning have been chosen from the area of coated and non-coated cemented carbides and cermets with respect to the used type of workpiece material. The work further deals with the possibility of their use under cutting conditions that are set to the upper cutting limits from the recommended range, especially without cooling. To obtain detailed information, the conditions of the test are further modified. Then, the results are also evaluated from the point of view of costs, i.e. market prices of inserts for possible application in the manufacturing process.
