Q. Explain Maximum Material (Metal) Conditions (MMC) and Minimum / Least
Material (Metal) Conditions (LMC).
Q. Explain Taylors principle applied to gauges.
Taylor’s Principle of Gauge Design:
The Taylor’s Principle of gauge design gives two statements which are discussed here:
Statement 1:
The “Go” gauge should always be so designed that it will cover the maximum metal
condition (MMC), whereas a “NOT-GO” gauge will cover the minimum (least) metal
condition (LMC) of a feature, whether external or internal.
Statement 2:
