## What is gage makers tolerance?

Gage tolerance is the gage’s increments of measure (also called resolution or discrimination). The AIAG guideline, called “The Rule of Tens”, states that gage resolution should divide process tolerance into at least 10 parts.

How do you tolerance a go no go gauge?

Ring Gauges receive the reverse tolerance direction so that the GO member is minus and the NO GO member is plus. 10 Percent Rule results in gauge tolerance always being included in the part tolerance by up to 10%.

How do I know my gauge tolerance?

To calculate the gage tolerance using the 10% product tolerance rule:

1. Calculate the full tolerance of the product feature.
2. Calculate 10% of the product feature tolerance to find the full gage tolerance.
3. Divide the full gage tolerance in half to find the gage member tolerance.

### Can go NoGo Gauge find out actual reading of the job to be tested?

It does not return a size or actual measurement in the conventional sense, but instead returns a state, which is either acceptable (the part is within tolerance and may be used) or unacceptable (the part must be rejected).

Why do we apply a gauge tolerance to gauges?

GAUGE TOLERANCE SELECTION Using the minimum diameter of the hole as the Go and applying the tolerance PLUS insures that, if the Go plug goes through the hole, the hole is larger than the the minimum diameter.

What are gauge pins used for?

Pin gages (also known as plug gages) are used to test hole size and it’s geometry.

## What are go no go gauges used for?

Go – No Go gauges are manual mechanical measuring tools used in production lines to guarantee the machining has taken place and it has been performed correctly. They differ from each other based on the type of surface check being performed; for example geometry and/or dimension.

How is gauge wear limit calculated?

GO max = dmax + Y1; GO max = 17,994 + 0,002 = 17,996 mm; for the gauge which is in operation GO max = dmax – Z1 + H1/2; GO max = 17,994 – 0,0025 + 0,003/2 = 17,993 mm; for the new gauge GO min = dmax – Z1 – H1/2; GO min = 17,994 – 0,0025 – 0,003/2 = 17,990 mm.

Are pin gauges accurate?

These gages have an inch tolerance of . 0002” and a metric tolerance of . 005mm. They are practical where good precision and speed are important.

### How many turns on a no go gauge is acceptable?

three complete turns
The use of NO GO gages and the limits of acceptance. 1 NOT GO (HI) Thread Plug Gages – Purpose and Use “NOT GO (HI) functional diameter is acceptable when the NOT GO (HI) thread plug gage applied to the product internal thread does not enter more than three complete turns. The gage should not be forced”.

What is the reason for applying gauge tolerance to gauges?
