ISO 16337 specifies guidelines for applying the robust tolerance design (RTD) provided by the Taguchi methods to a product to finalize the design of the product.
Note 1: RTD is applied to the target product to set the optimum tolerances of the design parameters around the nominal values. RTD identifies the effects of errors in the controllable design parameters on product output and estimates the total variance of the product output if the tolerances are changed. Hence, RTD achieves the target variance of the output from the viewpoints of robustness, performance, and cost.
Note 2: The tolerance expresses a maximum allowable error in the value of a design parameter in the manufacturing process. In a perfect world, the parts or elements of every product have the designed nominal values of the design parameters. However, actual manufacturing does not reproduce the exact designed nominal values of the design parameters for all products. The actual products have errors in the values of their parts or elements. These errors are supposed to be within the designed tolerances.
ISO 16337 on the application of statistical and related methods to new technology is applicable for:
If a manufactured product has errors from the designed nominal values, the product output will deviate from the designed value. The error in a design parameter should be smaller than the designed error limit to keep the product output within the designed variability. Therefore, the design parameters need a tolerance.
RTD (robust tolerance design), as described in ISO 16337 is a method for selecting the degree of errors of the parts or elements of the product from the viewpoint of variability under the optimum RPD (robust parameter design) condition, that is, the combination of optimum nominal values of the design parameters.
ISO 16337 enables you to cut production costs without compromising the performance of your products by guiding you to determine their RTD. ISO 16337 helps you to create more robust products which will help you minimize quality losses due to defects, failures and quality problems.
