There are four tolerances in the tolerance world, namely size, form, orientation and location, which are the four characteristics of the control element.
ISO2768, known as GB T1804 and GB T1184 after localization (note, this marking is only applicable to metal parts and sheet metal forming with material removed, not applicable to casting and injection molded parts).
ISO 14405-1 divides sizes into three main categories: local size, calculated size and global size, and each class includes several subclasses.

Anonymous users2024-02-14These two standards do not define the same tolerances. 2768 stipulates the length, chamfer, angle and shape tolerance of 286 with higher precision, generally used when there is a fit, such as shafts and holes, as well as slot keys for example, processing a length, width and height of 100x20x5 (mm) pieces, and then punching a hole with a diameter of 16mm in the middle. According to the accuracy of 2768m, the tolerance range of these dimensions is:
100( ,20( ,5( is the level of specifying the shape and position tolerance, specifically to this part is, flatness, verticality If the diameter of the round hole of 16 does not have any other identification, then according to the 2768 standard ( , if it involves cooperation, such as writing h7, f6 or something, it is necessary to implement it according to 286, such as 16h7 corresponds to 18 m, that is to say, the range is 16,018mm to 16mm

In the tolerance world, there are just four positive and large tolerances, namely size tolerance (chain size), shape tolerance (form), orientation tolerance (orientation) and position tolerance (location), these four tolerances are designed to control the four characteristics of the elements.
ISO2768, known as GB T1804 and GB T1184 after localization (note, this marking is only applicable to metal parts and sheet metal forming with material removed, not applicable to casting and injection molded parts).
ISO 14405-1 divides sizes into three main categories: local size, calculated size and global size, and each class includes several subclasses. The specific classification is shown in the following figure:
1. No documented provisions; 2. The rights and responsibilities of the relevant units are not specified; 3. Failure to specify the choice of ** business; 4. Failure to establish a list of recognized ** merchants; 5. The procurement object is not an approved ** businessman; 6. The first business object to be evaluated is not clearly defined according to the product type; 7. Failure to choose according to the ability of the ** business to meet the requirements of the contract; 8. There is no relevant record of evaluation or selection of approved ** businessmen; 9. The quality of the goods delivered by the merchant is often poor, and no effective improvement measures are taken; 10. The evaluation method of delivery of ** business is inappropriate or the record is not true; 11 **The information of the merchant is not updated regularly; 12. There is no follow-up reward and punishment management measures for the results of the delivery evaluation of the first business; 13. Before the procurement documents are issued, they have not been reviewed by the relevant authorities; 14. The requirements are not clearly stated in the procurement documents; 15 The application of relevant engineering information is not indicated....
1.At present, the market on the ISO9000 is not bad, but the enterprise system implementation personnel are not effective, 9000 is not a burden, but if the system implementation of the standard grasp ability is relatively poor, it will add a large number of cumbersome unnecessary records and procedures in the system for certification, the mentality of the report is of course rather useless 1000, not to make 1 slip through the net. In this way, how can the enterprise be overwhelmed? >>>More
