Aug 30, 2023 · Every feature of size has two size boundaries – the Maximum Material Condition (MMC) and the Least Material Condition (LMC). The Maximum Material Condition is the state in which the …

Jul 12, 2025 · In geometric dimensioning and tolerancing (GD&T), MMC (Maximum Material Condition) and LMC (Least Material Condition) are fundamental concepts that help ensure proper part fit and …

May 23, 2024 · GD&T MMC vs LMC – What are The Differences Between MMC and LMC? In GD&T, Maximum Material Condition (MMC) and Least Material Condition (LMC) are essential concepts that …

As the size of the pin departs from MMC toward LMC, a bonus tolerance is added equal to the amount of change. Bonus tolerance equals the difference between the actual feature size and the MMC of …

MMC is the condition of a feature which contains the maximum amount of material, that is, the smallest hole or largest pin, within the stated limits of size. LMC is the condition in which there is the least …

In this video, I explain the concepts of MMC (Maximum Material Condition) and LMC (Least Material Condition) in detail.

Maximum material condition (MMC) is used to indicate tolerance for mating parts such as a shaft and its housing. Least material condition (LMC) is used to indicate the strength of holes near edges as well …

For an internal feature of size, the MMC size is the smallest allowable size. For an external feature of size, the MMC size is the largest allowable size. When the MMC modifier is used, it indicates that the …

MMC and LMC are defined the way they are--as maximizing or minimizing the amount of material--to make it easier to see and understand these relationships between tolerances.

When should we use MMC (Maximum Material Condition), LMC (Least Material Condition) and RFS (Regardless of Feature Size)? What are the practical implications of these modifiers? This text …
