Design of CNC lathe broaching head
Boháč, Josef ; Knoflíček, Radek (referee) ; Tůma, Jiří (advisor)
This bachelor’s thesis deals with the design of construction of broaching head for CNC lathe. This thesis is divided into research part, computational and construction part. The research part is dealing with the CNC lathes and tools with focus on the BMT and VDI tool turrets. Based on the outputs from the research, design parameters and suitable construction solution was chosen. The chosen construction solution uses the crank mechanism. This part is followed by the computational part which includes strength calculations of construction parts and other parameters such as cutting force. The last part is dealing with the construction of the broaching head itself. This thesis also includes a 3D model, drawings of selected parts and an assembly drawing.

Design of tool turret for CNC lathe
Navrátil, Lukáš ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis deals with mechanical design of tool turret for CNC lathe. The first part of the thesis is dedicated to research of automatic tool exchange and current trends in design of tool turrets with drive of rotary tools. The second part is focused to design of tool turret, which is based on the findings of the research part of the thesis. The design includes calculations of machining loads, spindle deformation, bearings, gears and spindle startup. Furthermore, 3D models and selected drawings are included.
