Design and Fabrication of Ultrasonic Machining Machine and Investigating Parameters Affecting on Glass Machining Mohammad Ahmadi November 2020 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 IranAbstractIn recent years the application of oscillations caused by ultrasonic waves in various industries hasbeen increasing rapidly Therefore extensive researches in various industrial fields based on theapplication of these waves began to be beneficial in optimizing the parameters affecting themethods based on the use of these waves One of the special uses of ultrasonic waves is using inmachining hard and brittle materials in a method called ultrasonic machining Researches on thismethod is also expanding due to specific applications in various industries These researches aredone in two main parts The first part is related to the upgrading and improvement of themachine mechanisms and the second is in the field of investigating and optimizing themachining parameters on different materials In the first step design fabrication of theultrasonic machining equipment was done Then in the second step by designing a set of tests drilling operations were performed under different machining conditions on a glass sampleworkpiece in order to ensure the proper operation of the machine Results of the finite elementmethod used to design the transducer and tool set were very close to the actual conditions and thismethod can save time and money The results of practical tests also showed that with increasingdepth of cut the amount of lateral overcut increases Also drilling with this method is done moreeasily when the tool is rotating but the amount of the lateral overcut is also increased Machiningwith fixed tool is also not recommended if the shape of the tool is symmetrically axial Because theaccumulation of chip particles and its difficult exit from the machining area with increasingpressure will cause damage to the workpiece or tool It should be noted that with the fabrication ofthis equipment it will be possible to continue research and development in both of above mentionedresearch field Keywords Ultrasonic Machining Modern Machining brittle Material Machining TransducerDesign Horn Design Finite Element FEM Rotary Transducer
