Abstract: There is a relatively vast class of tool path optimization
methods that minimize cost functions depending
on a whole tool path. In these methods, cost functions
are usually limited to convex function because the used
optimization approaches cannot either handle nonsmooth
functions or perform with an acceptable computational time.
This paper describes a developed optimization method that
finds a sequence of tool orientations that can minimize various
cost functions including displacement of machine rotary
axes. Every posture, tool feasible orientation can be represented
in discrete fashion as nodes of a directed graph
in which the edge weights denote an objective. Shortest
paths are sought iteratively by applying Dijkstra’s algorithms
and narrowing intervals of feasible tool orientations
around the previous solution. The developed algorithm is
a derivative-free optimization method working in a linear
