THE DETERMINATION OF TOOLED DIMENSIONS WITH RESPECT TO MUTUALLY INTERCHANGEABLE ADJUSTMENT AND THE VALUE OF THE PERMISSIBLE MEASURED WEAR OF A TOOL,
Abstract
A new practical method is proposed for determining the 'tooled' dimensions in the mutually interchangeable adjustment of metal-cutting machines, as it would apply in evaluating the permissible measured wear of a tool. This method involves machining specially prepared parts (blanks) using two sets of critical characteristics: (1) with minimum allowances (tolerances) and minimum hardness (temporary resistance), and (2) the largest critical characteristics. Authors mention that a number of original errors are not taken into account using this method, and they include: geometric errors in the equipment, random assembling errors at the installation and in fastening components, measuring errors and temperature deformations of parts, tools and equipment.
