Tolerance and accuracy in production: what is it and how to achieve them?

Admission is an allowable deviation of the size, shape, location and other parameters of the part or node from the nominal values set by the drawing or technical conditions. Accuracy is the degree of conformity of the actual values of the parameters of the product to their nominal values. In this article, we will consider what tolerances are and how to achieve high accuracy in production.

Types of tolerances
There are several types of tolerances that are used depending on the type of production and product quality requirements. The main types of tolerances include:

Size tolerances: these are permissible deviations of the sizes of parts from nominal values.
Tolerances of the form: these are permissible deviations of the shape of parts from the nominal shape.
A tolerance tolerance: these are permissible deviations of the location of the surfaces of parts relative to each other.
Tolerance tolerances: these are permissible deviations of roughness of the surface of the parts from nominal roughness.
How to achieve high accuracy in production?
To achieve high accuracy in production, the following principles must be observed:

The use of high -quality equipment: the use of modern equipment with high accuracy and reliability will help to achieve high accuracy in production.
Quality control: Conducting quality control at all stages of production will help to identify possible errors and fix them before they lead to marriage.
Personnel training: staff training in the correct use of equipment and compliance with technological processes will help improve the quality of products.
Implementation of the quality management system: the introduction of the ISO 9001 quality management system will help control all production processes and achieve high accuracy at each stage.

In conclusion, tolerances and accuracy in production are important aspects of product quality. To achieve high accuracy, it is necessary to use modern equipment, conduct quality control and train staff. The introduction of a quality management system will help control all processes and achieve high accuracy at each stage of production.
