tolerance for slip fit joint?

[Orlando]

Hello, does anyone know what the LMC and MMC for a hexagonal joint that is 2.2238 mm. and a shaft that is 2.3 mm made from polypropylene?

Hi Orlando,
It is a GD&T term. Least Material Condition and Maximum Material Condition. There are to do with tolerances such as in your case when there is a shaft and a joint. If you every need GD&T help contact these guys: http://symphonytech.com/

Definitions of MMC and LMC:

MMC is that limit of size within the tolerance of size which retains maximum material on the workpiece. Hence it's the largest shaft or the smallest hole within the tolerance of size.

LMC is that limit of size within the tolerance of size which retains least material on the workpiece. Hence it's the smallest shaft or the largest hole within the tolerance of size.

A toleranced drawing of the component you are talking about will help to comment upon the MMC or the LMC limits.

Thanks.
