In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...

air spindles are one of the main elements of precise machine tools. vibration of these spindles is one of the vital issues necessary for investigation. among parameters which influence air spindle vibrations are rotational speed, compression air method, input nozzle diameter, air gap pressure. in this study using ansys, the effects of air gap thickness on air spindle vibrations have been invest...

In textile industries, spinning sector plays a vital role because this produces the main raw material for industries which is known as yarn. So getting good qualities garments, it needed to ensure There are many things re-sponsible producing Among these spindle speed an important thing. One must have change speed, when he changes count. As every count has particular in production shows maximum ...

INTRODUCTION The analytical stability lobe diagram offers a predictive capability for selecting stable chip width-spindle speed combinations in machining operations [1-4]. However, the increase in allowable chip width provided at spindle speeds near integer fractions of the system’s dominant natural frequency is diminished substantially at low spindle speeds where the stability lobes are closel...

With the increase of spindle speed, heat generation becomes crucial problem high-speed motorized spindle. In order to obtain actual thermal behavior a spindle, digital twin system for characteristics is developed in this paper. The mechanism simulate machine tool through mapping and correcting boundary conditions using data acquisition correction models. proposed includes three modules which ar...
