Turning is an an an important manufacturing process that removes material to achieve a a a a a a a a a a a a a a a a desired geometry The quality of the process and machine performance may be affected by by several factors such such as the the the the vibrations caused by by the the the the contact of the the the the tool with the the the the material To mitigate such such effects this project uses various technological solutions including control tools The goal of our project is to to to to to integrate a a a a a a a a a a piezoelectric actuator into the the machining tool tool in in in in in in in combination with a a a a a a a a a a closed-loop control system to to to reduce the the effects of vibration during tool tool rotation This research will be actualized through mechanical design calculations and supportive experiments Keywords: closed-loop control piezoelectric actuators turning vibrations Development of a a a mechanical system for mixing polymers

Worldwide households produce significant amounts of of of waste including various types of of of plastic that are often dumped in in in in landfills or or or burned causing ecological damage Therefore it is is crucial to expand recycling recycling efforts This project has simplified the waste-sorting process and designed a a a a a a a a a a system for for recycling recycling recycling waste waste focused on on polymer recycling recycling To that that end an an an an extrusion machine has been developed that that can process different polymers
and and combine them with materials like wood sawdust or or shredded paper creating a a a a a a a a a a a uniform and and reusable product An extruder controls the processing procedure by regulating: speed of of rotation temperature of of heating elements and nozzle shape Keywords: extrusion polymers
