Molding technology is one way of producing the micro-precision parts required by various industries. To Advance this molding technology, various elemental technologies related to materials, construction and machiningmethods are evolving together. One of these elemental technologies is milling by end mill. Further research and development of end mill is underway in response to improvement and requirement of molding technologies. There are various demands for end mills such as improvement of tool life and stable machining quality. Here we report the small diameter cBN end mill, developed as a tool to provide with stable machining accuracy with long tool life for high hard materials. We report the investigations and characteristics at the time of development and show the machining test.

The Impact

In practical production, the evaluation method of tool life that heavy forging shell ring is in hogging machining compare the length of its processing surface in a single direction, the method considers neither the actual cutting distance of cutting tool, nor the impact times sustained by the cutting tool, this paper provides a new method of tool life evaluation based on image processing technology. Through collecting images of processing surface of the work-piece, which contains the different colors and brightness caused by processed and unprocessed, and image processing, analysis and calculation, the new method can accomplish the calculation about the effective cutting distance of cutting tool and the number of impact force about cutting tool, it will be more scientific and more reasonable evaluation method of tool life. Finally, one example is given. New method can be used to provide accurate evaluation of tool life and material machinability for the machining of large forgings.

Chemical mechanical polishing/ planarization (CMP) is a key technology for fabricating high-efficient semiconductor devices, and the CMP characteristics (removal rate and accuracy, etc.) is depended on the various consumables represented by slurry, polishing pad and dresser used in the CMP process. Currently, in the pad, there are many studies that have pointed the evaluation methodology and the correlation between the pad surface asperity and the CMP characteristics. On the other hand, the dresser is one of the most important consumables because the dresser can control the pad surface asperity, and the diamond grains electrodeposited dresser (diamond dresser) is frequently used. One drawback point of the diamond dresser is that the dressing performance declines owing to the deterioration of the diamond grains. Previously, we have developed a novel flexible fiber dresser that would ensure high performance and longer life of tools, and we have reported the fundamental characteristics by the flexible fiber dresser compared with that of the diamond dresser. In this paper, we will show the results of tool life evaluation of the flexible fiber dresser using a contact image analysis method. As a result, the flexible fiber dresser can be continuously used over 35 hours. Furthermore, the result of having examined the stability of the removal rate of a silicon wafer is reported. Therefore, we found that the flexible fiber dresser is one of the most effective dressing methods for the polishing pad.

Machining Test

Metalworking fluids (MWFs) can greatly improve the machinability of materials and increase cutting tool life. There are a range of MWF products available on the market, however there are very few reliable low cost machining based fluid screening tests which can help select the most suitable candidate. This study developed a novel and rigorous single point milling (SPM) procedure carried out under controlled conditions, which would provide fluid performance differentiation for a range of typical aerospace alloys. The use of a single insert with a controlled geometry reduced machining variance and ensured performance repeatability. Tool life curves were used to determine optimum machining surface speeds for Inconel 718 (In718) of 80 m/min and Ti-6Al-4V (Ti64) of 160 m/min. Carrying out trials using five different cutting fluid products within a controlled tool life window clearly demonstrated that the SPM machining test was able to differentiate performance on both In718 and Ti64 material. Overall a 65% and 53% performance difference in tool life behaviour was observed between the best and worst performing fluids for In718 and Ti64, respectively.
