Rake angle measurement of inclined slotting cutter
This paper analyses the blade shape, the parameters of rake angle of slotting cutter. The theoretical analysis process of a novel rake angle error measurement is introduced, which is built on the theory that the rake face of the inclined slotting cutter is a flat surface. For the systematic errors is caused by inaccurate measurement, the paper give in-depth analysis in various situation. By testing in the GD40-type CNC Gear Measurement Center, the accuracy testing results validate the correctness of the method.
Research on the design and manufacturing of an outer cycloid slotting cutter
Outer cycloid gears are used widely in many instruments and machines. The outer cycloid slotting cutter is an important cutting tool used in the manufacturing of this type of gear. In the process of design, the ideal outer cycloid cutter is one where a cylindrical surface takes the tooth profile of the outer cycloid as the directrix. However, during the manufacturing process, it is used as a cutter and therefore a cutting edge is required. As a result, it will be seen that the processes of design and usage of the outer cycloid cutter are not the same. The range of the qualified length of tooth is deduced in this paper by using the mid-point and mid-line method. This paper also presents the associated outer cycloid slotting cutter design and manufacturing models so that the modelling accuracy and the necessary relief angles of the top cutting edge and side cutting edge can be ensured. This paper is intended as a reference to be used in the manufacture and application of this type of slotting cutter.
The Analysis of Proper Meshing Between a Pair of Non-circular Gears Manufactured by Involute Cylindrical Gear Cutter
In this paper, we proved that there exists on ly one contact point between a pair of non-circular gears working under the des igned pitch curves when they are manufactured by involute cylindrical gear cutte r in numeric control slotting machine. Under this manufacturing condition, the p air of non-circular gears can mesh accurately.
