G D & T symbols are geometric dimensioning and tolerancing symbols used to define the geometry of parts and assemblies.

• G D & T symbols are used to specify the allowable variations in form, size, orientation, and location of features on a part.

• Examples of G D & T symbols include concentricity, perpendicularity, flatness, and position.

• These symbols help ensure clear communication between designers, engineers, and manufac...read more

SPC stands for Statistical Process Control. Cp and Cpk are indices used to measure process capability.

• SPC is a method of quality control which uses statistical tools to monitor and control a process.

• Cp is a measure of process capability that compares the spread of the process to the tolerance range. Cp = (USL - LSL) / (6 * standard deviation)

• Cpk is a measure of process capability that accounts for process centering. Cp...read more

The instruments least count I use vary depending on the specific instrument, but typically range from 0.01mm to 0.001mm.

• Least count refers to the smallest measurement that can be read on a particular instrument.

• Common least counts include 0.01mm for vernier calipers, 0.001mm for micrometers, and 0.1g for weighing scales.

• Choosing the appropriate instrument with the right least count is crucial for accurate measurements.
