Studies on Centerless Grinding (2nd Report)

Determination of waviness decrease rate by measuring the frequency characteristics of the grinding force in centerless grinding

“…κ = K m /(K m + K s ) (K m , the machine stiffness and K s , the grinding stiffness), the machiningelasticity parameter [3], can be obtained from the timeconstant of the grinding force and the workpiece rotation speed [8]. It is obvious from Eq.…”

“…The authors have proposed the optimum grinding conditions for minimizing workpiece roundness error [8]. However, the process parameters selected based on the proposed optimum grinding conditions might become unsuitable during grinding as the grinding wheel and regulating wheel are wore down during grinding.…”

A new in-feed centerless grinding technique using a surface grinder

“…Rowe and Bell (1986) experimentally investigated the high removal rate grinding process and optimized the grinding conditions. Wu et al (1996) clarified the influence of grinding parameters on roundness error through a computer simulation method to optimize grinding conditions. Epureanu et al (1997) analyzed the stability of grinding system through a linearized model that described the formation and evolution of the pattern on the ground surface.…”

Effects of process parameters on workpiece roundness in tangential-feed centerless grinding using a surface grinder

“…Two types of centerless grinders are available commercially, one that uses a regulating wheel and one that uses a shoe, and these grinders are different in how they support the workpiece and control the workpiece rotational speed. Especially since the invention of the regulating wheel type centerless grinder by Heim in 1915 (Yonetsu, 1966), much research has been devoted to clarify the rounding process by Rowe et al (1964Rowe et al ( , 1965, optimizing the machining conditions by Rowe and Bell (1986) and Wu et al (1996), achieving stability of the workpiece during grinding by Miyashita et al (1982), Epureanu et al (1997) and Albizuri et al (2007), and achieving safe machining operation by Hashimoto et al (1982) for the sake of enhancing machining accuracy and efficiency. Shoe type centerless grinding has also attracted attention from both industrial and academic researchers.…”
