The hobbing finish of hard gear teeth such as case-hardened gears is anticipated for practical use in high efficiency production. We studied wear and finished surface properties in cutting tests using a cubic boron nitride (cBN) hob cutter in high-speed cutting at 900 m/min of case-hardened steel. The cBN content in tip ingredients is related to wear, and tips high in cBN content are superior in wear resistance. The high thermal conductivity of cBN tips helps transfer cutting temperature heat to chips, melting and adhering them to the relief surface. Flaking may occur on the cutting edge but new chipping does not occur although chipping may exist after grinding. Finished surface roughness is influenced by horning on the cutting edge. Round horning leads to a smooth surface. High-speed finishing with cBN-tipped hobs is analyzed in view of cBN tip grinding and finished surface properties, in addition to wear properties.

The Impact

High-speed machining (HSM) is very useful method as one of the most effective manufacturing processes because it has excellent quality and dimensional accuracy for precision machining. Recently micromachining technologies of various functional materials with very thin walls are needed in the field of electronics, mobile telecommunication and semiconductors. However, HSM is not suitable for microscale thin-walled structures because of the lack of their structure stiffness to resist high-speed cutting force. A microscale thin wall machined by HSM shows the characteristics of the impact behavior because the high-speed cutting force works very shortly on the machined surface. We propose impact analysis model in order to predict the limit thickness of a very thin-wall and investigate its limit thickness of thin-wall manufactured by HSM using finite element method. Also, in order to verify the usefulness of this method, we will compare finite element analyses with experimental results and demonstrate some applications.
