when i read a drawing it contain tolerance of position dia 0.02@RFS
IN this what is the meaning of RFS
The Modifiers (MMC,LMC,RFS) are used to clarify implied tolerances. There are three directly implied modifiers to the tolerance value. These are;
1-) Regardless of Feature Size (RFS)
2-) Maximum Material Condition (MMC)
3-) Least Material Condition (LMC)
Regardless of Feature Size (RFS): RFS is the default modifier. so if there is no modifier symbol shown in feature control frame, it meansRFS is the default modifier. RFS is used when the size feature does not affect the specified tolerance.
