This paper starts with experimental observations regarding positional and size errors when drilling holes. Based on these observations, statistical models relating production errors to position tolerance of a hole are presented. 2-D models for RFS and MMC position tolerance specifications are developed. Modeling is extended to a special 3-D case including orientation errors. Numerical applications show the effects of various parameters on the probability or an acceptable hole. Use of a simulation package for the solution of these problems is also discussed. These models and solutions may help manufacturing select equipment with the accuracy and precision required to meet design tolerance specification.
