Max material condition and bonus tolerance
Web17 aug. 2024 · Bonus tolerance is the difference between the actual feature size and the LMC of the fea- ture. The bonus tolerance is added to the geometric tolerance specified in the feature control frame. LMC is used to maintain a minimum distance between features. The LMC is seldom used. Functional gages cannot be used to inspect features … Web18 nov. 2010 · I have read recommendation to distribute clearance for positional tolerance as 60% for thread hole and 40% to drill hole. Then it will be Ø.062"*0.6=0.0372. For hole with min PD 0.6850 0.1 will apply. if PD will grow then positional tolerance will grow accordingly and max will be 0.1+ (0.6927-0.6850) = 0.1077.

WebOne basic function of the true position tolerance is to prevent a component from forcing another component out of alignment at assembly time. It takes into consideration the allowable deviation of sizes of the relevant features of an assembly. For example: a screw that binds multiple components together. Web25 mrt. 2024 · When parallelism tolerance is in reference to a surface plane, material modifiers cannot be used. But in the case of axis parallelism, both LMC (least material condition) and MMC (maximum material condition) are allowed. The bonus tolerance (difference between LMC/MMC and the actual condition) comes into the picture when …
