Selection and Analysis of Spindle and Ballscrew of CNC Machine

This book is a study about the critical components of CNC machine. As performance of CNC machine great depends on its main or critical components i.e. spindle and ballscrew, and this performance is interrelated with machine tool and machining process. Initially we take spindle for analysis in this report. For analyzing force we take most common process perform on CNC machine say drilling process and turning, in which torque and thrust force is generated, and this force calculated by mathematical modeling. Using this torque and thrust force we are analyzing in ANSYS 13.0 Workbench software. These software gives the most preciously result in analysis and optimization point of view. As the critical components like spindle and ballscrew is to be analyzed for that stress analysis, total deformation and maximum shear stress is carried out in the software. Using this FEA analysis optimization of spindle is being done. And another critical component of CNC machine i.e. ballscrew is analyzing and further checking their acceptability whether it is working within permissible limits or not. And also selection methodology of ballscrew and service life is to be calculated.
