Abstract
In our previous research it was proposed to evaluate a part upon its process planning difficulty perceived by engineer in process planning. In this paper the extended research is going to be described. It takes into account the differences in the perception of the difficulty in process planning among different manufacturing culture and environments in which engineer works. The research work started with an investigation delivered in a number of machine tool companies in different countries. The results of the investigation were then analyzed using various means, including a multiple regression analysis, to find out which influential factors are typical for a manufacturing culture and thus impact an engineer's consciousness about process planning difficulties. On this basis, an "engine" that would take into account the values arrived at in difficulty evaluation was developed. This engine could thus be used to predict the deviations of the difficulty evaluation in different manufacturing culture and environments.
