State the industrial applications of slip gauges
Answers
They are used as a reference for the calibration of measuring equipment used in machine shops, such as micrometers, sine bars, calipers, and dial indicators (when used in an inspection role). Gauge blocks are the main means of length standardization used by industry.

Explanation:
Slip gauges (or their gauge/gauge equivalents) are the universally accepted "length standard" in the manufacturing and engineering industries. As a result, they are used in the calibration and verification of many different instruments and equipment during the CNC machining process.
The advantage of slip gauge standards for dial comparators is that the size of the standard is equal to one of the size limits of the plug gauge, and thus the influence of comparator scale errors is minimized.
How slip gauges cause error
The use of a caliper is a manual process performed by an operator or machinist. Achieving optimal accuracy in this process is a highly skilled procedure that is difficult and time-consuming and carries the risk of introducing human error. Involving multiple operators increases this risk of error as it is possible that they could end up with different results. And since slip gauges offer little help in verification, there is no way to know which result is correct or not.
Let's look back at the process of setting up the probe and determining the location of the Z axis. If the result here is not accurate, it starts a chain reaction of errors that propagate through the CNC machining process and affect the accuracy of the part - which can lead to failed inspections, rework and high scrap.
