| Research Abstract |
This research presents originally the experimental measurement method of the machining accuracy in the ball-nosed end milling. This method makes it possible to machine in every tool orientation with the three-axis-controlled machine tool. The machined surface profile is precisely measured by the noncontact 3-dimensional measuring instrument. Several experimental results in some cutting conditions are presented. The relationship of tool orientation and machining accuracy was clarified. The adequate and inadequate tool orientation was found. In addition the reasonable tool orientation on ball-nosed end milling was discussed comparing with the experimental results and the geometric analysis of the undeformed chip thickness.
1)The experimental measurement method of the machining accuracy in the ball-nosed end milling is presented. This method provides very efficient and accurate experiment.
2)The influence of the tool orientation to the machining accuracy is clarified in experimental. So the tendency to overcut and another tendency with the inclination angle is observed
3)The surface roughness is varied as the feed direction is changed. This phenomena depends on the direction of the cutting edge sweeping.
