Lobing Behavior in Centerless Grinding—Part I: Stability

This twopart paper addresses the lobing behavior associated with centerless grinding Part I establishes a system model (the lobing loop) for lobing analysis and develops methodologies for lobing stability analysis, and Part II investigates lobing characteristics and proposes remedies for lobing suppression The lobing loop shows A multistage approach for the execution of plunge centerless grinding operations aimed at accelerating waviness reduction in workpiece initial profile is proposed It consists in dividing the process into 2 or more stages characterized by different processing parameters, eg workpiece heights Even though process splitting in roughing andMultistage centerless grinding setup via discrete mapping

Roundness prediction in centreless grinding using physics

11 Centreless grinding As Dhavlikar et al describe centreless grinding is a common manufacturing grinding process for round workpieces, thanks to its unique workpiece (WP) holding systemThe WP is sustained along three contact lines, with the grinding wheel, the regulating wheel and the supporting blade (Fig 1)This method With the infeed method, the regulating wheel spins the part at one speed while pushing it towards the grinding wheel, which is spinning at a faster speed The greater the difference in speeds, the faster the removal rate 4 The choice of grinding wheel is critical Another key factor in centerless grinding is the choice of grinding wheel8 Principles of Precision Centerless Grinding Metal Cutting Corporation
