Every feature on products or parts has a size and a geometrical shape.

ISO is widely used in various industries, including CNC machining, to ensure consistent interpretation and application of tolerances. It is also available as a DIN standard in Germany. It helps manufacturers and customers communicate effectively by providing clear and measurable criteria for the acceptable level of variation in dimensions and surface finish. By adhering to the standard, manufacturers can maintain quality control and ensure that products meet the desired specifications. ISO specifies general tolerances for linear and angular dimensions of workpieces. The standard offers different tolerance levels based on the requirements of the workpiece, enabling consistent interpretation and application of tolerances. ISO focuses on surface roughness requirements.

Specialize in CNC machining, 3D printing, urethane casting, rapid tooling, injection molding, metal casting, sheet metal and extrusion. Rapid manufacturers design and manufacture large quantities of metal or plastic parts every day. All manufactured parts vary in size and physical appearance, and prototype parts, especially, may be unique in the world. However, it can be very challenging to manufacture these plastic or metal parts without deviating from the original design intent. Ensure reasonable tolerances to adhere to correct size and shape. Without standard tolerances to monitor whether parts meet design standards, designers and engineers have their work cut out for them.

There are a large number of spare metal or plastic parts will be designed and manufactured every day. If there is no tolerance standard to manage the dimensional of products, the designers and mechanics will be crazy, because it will add a lot of difficult work. In order to simplify the design and production of Machinists, the international tolerance organization has developed and issued this international tolerance standard, which can be used for machining, cutting, and other parts. In this article, we will introduce ISO in detail. ISO is an International Standard that created by the International Organization for Standardization ISO , it is intended to simplify drawing specifications for mechanical tolerances. Its creation and implementation make design and production more convenient, and make cooperation between different companies easier and closer. ISO mainly applies to parts manufactured by machining or material removal. For part sizes without marked tolerance ranges, this standard should be followed. Please note that all tolerance limits are given in mm. ISO is intended to simplify drawing indications and specifies general tolerances in 4 tolerance classes f — fine, m — medium, c — coarse, v — very coarse.

It establishes tolerance values that aid in streamlining the design and production processes. If the form elements have the same nominal dimension, either one can be used as the reference element.

Dimensional tolerance is of great importance in precision CNC machining as it directly affects the accuracy and functionality of machined parts.

ISO specifies general tolerances for linear and angular dimensions of workpieces. The general tolerance for parallelism is equal to the numerical value of the dimensional tolerance or the flatness or straightness tolerance, whichever is larger. ISO - 1: Linear and Angular Dimensions ISO aims to simplify drawing indications and provides general tolerances categorized into four tolerance classes: fine f , medium m , coarse c , and very coarse v. If both form elements have the same nominal dimension, either one can be used as the reference element. Table 1. Table of Contents Toggle. When figuring out the right level of tolerance for a part or product, factors like materials, proceses, and costs should also be taken into consideration. If the general tolerances for dimensions tolerance class m do not apply, the corresponding code letter is omitted. The general tolerance for roundness is equal to the numerical value of the diameter tolerance. The longer of the two legs forming the right angle is used as the reference element. My Messages. On the contrary, a larger tolerance range would be more cost-effective if the part is produced in high volumes for lower-level tolerance applications. However, it must never exceed the value specified in Table 2.
