Question

When the measured dimensions of the workpiece are not consistent with the regulations, the difference is (    )

A. Dimensional tolerances

B. Dimensional deviation

C. Dimensional error 

Answer 1

When the dimensions measured in the workpiece processing are inconsistent with the regulations, the difference is the dimensional error.

This question chooses C answer, size error.

Answer 2

When the measured dimensions of a workpiece are inconsistent with the specified standard, this difference is called "dimensional deviation" or "dimensional error". Dimensional deviation is the difference between the actual measured dimension and the theoretical specified dimension, which reflects the degree of deviation in the machining accuracy of the workpiece.

This deviation may be caused by a variety of factors, such as the accuracy limitations of the processing equipment, the skill level of the operator, changes in material properties, and the accuracy of the measurement method.

For dimensional deviation, detailed analysis and evaluation are required to determine the cause of its occurrence, and appropriate measures are taken to adjust and improve it to ensure that the workpiece dimensions meet the specified requirements and ensure the quality and performance of the product.
