Summary.
Within the P.%RTC'APP system. the selection of an optimum operation sequence is related to the modules which perform the machiningmethtdand
cutting tool selection. This study analyzes the technical and economical aspects of operation sequencing and presznts a method which is capable of
senerating an ciptimum solution o n the basis of previously selected machining operations and alternative cutting took per operation. Precedence
relations between operations provided by the methodselector are usedasconstraintswhich shouldnot beviolated. The operationsequencing method
simulraneously assigns single tocils from a list of alternatives to tach operationand manipulatesthe operation sequence inorder t o minimize the total
number of toolchanges and the number of required tools.
