Total runout is the combination of radial and axial runout, while runout refers to the deviation of a surface from a true circular path.

• Total runout includes both radial and axial components of runout.

• Runout specifically refers to the deviation of a surface from a true circular path.

• Total runout is a more comprehensive measurement of overall part quality.

• Runout is typically measured using a dial indicator or similar to...read more

Use a straight edge or surface plate to check flatness of uneven surface.

• Use a straight edge or surface plate to check for any gaps or rocking on the surface

• Measure the deviation from flatness using feeler gauges or dial indicators

• Check for any high spots or low spots on the surface

• Repeat the process in multiple directions to ensure overall flatness

Jigs guide the cutting tool, while fixtures hold the workpiece in place during machining.

• Jigs are used to guide the cutting tool, ensuring accuracy and repeatability.

• Fixtures are used to hold the workpiece in place during machining operations.

• Jigs are often used in drilling, tapping, and reaming operations.

• Fixtures are commonly used in milling, grinding, and welding processes.

Mould flow analysis is a simulation technique used to predict how molten plastic will flow in a mold during the injection molding process.

• Helps optimize the design of the mold and the injection molding process

• Identifies potential issues such as air traps, weld lines, and sink marks

• Allows for adjustments to be made before physical production begins

• Can improve part quality and reduce manufacturing costs

Cp and Cpk are process capability indices used to assess the ability of a process to produce output within specification limits.

• Cp is a measure of process capability that compares the spread of the process to the width of the specification limits.

• Cpk takes into account the centering of the process within the specification limits as well.

• Higher values of Cp and Cpk indicate better process capability.

• For Cp, a value of 1...read more
