This article explained the tolerance analysis method in the micro-manufacture area on the keychain cranioplasty plate product dimensions. This research aimed to compare the simulations of keychain cranioplasty plate product dimensions using the ISO 286 tolerance standard. The manufacturing process to produce the keychain cranioplasty plate used the blanking process. The dimensions analysis aimed to observe the effect of punching speed and tool punch material on the product’s quality. The ISO 286 tolerance on blanking product used IT Grade of 10 for the punching process. The keychain cranioplasty plate dimensions from the blanking process simulation had an excellent quality if the sizes were close to the actual product’s dimensions. The keychain cranioplasty plate product had to have a high precision level between 10–100 μm so that the medical field could use it. © 2020 Trans Tech Publications Ltd, Switzerland.
