This article focuses on the issue of controlling cutting conditions in point milling strategies in order to reduce machining time.Using cutting tools with a circular cutting edge during point milling strategies of complex shape parts the actual contact point between the tool and the workpiece continuously changes. According to this fact the cutting speed also changes continuously and the required cutting speed is not achieved along the toolpath. Therefore, a solution to control the spindle speed has been developed to achieve the constant value of cutting speed and consequently provide a solution to control the feed-rate in order to maintain the constant value of feed per tooth.
