GD&T symbols are used to specify geometric tolerances on engineering drawings.

• GD&T stands for Geometric Dimensioning and Tolerancing

• It is a system of symbols used to specify the allowable variation in form and size of features on a part

• Examples of GD&T symbols include: flatness, perpendicularity, concentricity, and position

• GD&T is important for ensuring parts are manufactured to the correct specifications and fit toget

True position on CMM can be checked using a combination of software and hardware tools.

• Use a calibrated probe to measure the feature location

• Compare the measured location with the nominal location

• Calculate the deviation and compare it with the tolerance

• Use software tools like GD&T to analyze the results

• Ensure the CMM is calibrated and the probe is in good condition

FMEA stands for Failure Mode and Effects Analysis. It is a systematic approach to identify and prevent potential failures in a process or product.

• FMEA is used to identify potential failures in a process or product and their effects on the system.

• It involves analyzing the likelihood of failure, severity of the consequences, and the ability to detect the failure before it occurs.

• FMEA is commonly used in industries such a...read more
