Today, almost every manufacturing process of CNC machined parts contains at least some of the drilling operations. Most common tool for drilling is head drill, which wears during exploitation. To maintain functionality like the first time it is used, it is recommended to sharpen it properly. That is why the subject of this master’s thesis is the designing process of head drill sharpening fixture. Many of machining operations are used during drilling, starting from usually first operation, that is center drilling, all the way to the operations of deep hole drilling. Every of this operation and tools needed to perform them are explained in second chapter of this thesis. In third chapter are explained characteristics of hole processing, to be more specific, types of tools for drilling, machining parameters for drilling and tool wear. Main subject of this thesis is explained in chapter four, where it is given CAD presentation of head drill sharpening fixture. There have been explained technical characteristics of fixture and its assembly and manufacturing documentation. Just like the functionality of the fixture, it is important to be operated and handled properly to prevent workers injuries. More on this subject will be explained in chapter five. Based on all previous chapters, on the end of this thesis it is given a conclusion on possibilities and usability of head drill sharpening fixture and its application in manufacturing.
