Centerless grinding terminology “Infeed grinding” in centerless grinding is essentially the same method as plunge grinding. Is this statement correct?

Introduction / Context:Centerless grinding methods include through-feed, infeed (plunge), and end-feed. Correct terminology helps in process planning and wheel dressing strategy.

Given Data / Assumptions:

• Cylindrical work not supported by centers; supported by work rest blade.
• Regulating wheel controls rotation and feed.

Concept / Approach:Infeed grinding—also called plunge grinding—feeds the work radially into the wheel for grinding shoulders, grooves, or profiles. There is no axial movement of the work past the wheel as in through-feed.

Step-by-Step Solution:Define infeed: radial feed into the grinding zone.Match to term “plunge grinding”: identical concept and application.Conclusion: statement is correct.

Verification / Alternative check:Process descriptions in handbooks commonly treat “infeed (plunge) centerless” as synonymous.

Why Other Options Are Wrong:Through-feed involves axial passage; taper grinding uses angular setup; the synonymous use is not limited to special machines.

Common Pitfalls:Confusing through-feed with infeed; attempting to grind shoulders in through-feed mode.

Final Answer:Yes
