Micro products or micro components are commonly used in today’s world. Research around micromanufacture technologies to produce a better product quality has been going on extensively. Ultrasonic vibration assisted micromilling (UVAM) is one of the technologies that can give a better machining qualities over the conventional ones. One of the benefits UVAM can give is reducing the machined surface roughness. The purpose of this paper is to give an idea how vibration assisted micromilling can give a better surface roughness quality. The theoritical surface roughness geometry model is made using MATLAB software. The cutting tool used in the simulation is end mill. There is a feature of the cutting tool called bottom cutting edge angle. This feature will be considered on this paper. The effects of the bottom cutting edge on workpiece machined surface can be looked visually from the simulation. Thus, the effects of cutting process using UVAM on the workpiece surface can be looked as well through the simulation.

In recent years, a micro reactor used in the chemical field is capable of compounding reagents by the fine passage that intersects with in a complicated manner. The micro reactor is requested to have a high-quality finish because it uses not only a general acryl material, but also a hard vulnerable material such as a glass with excellent corrosion resistance. Etching technology is used as a method to provide a fine groove, but it requires tremendous amounts of money. This study attempts to manufacture the micro reactor using micro cutting by a non-rotational tool to process hard vulnerable materials. Processing in the ductile mode is indispensable for processing of a hard vulnerable material such as a glass. If this is realized, a good finish can be obtained. In this report, processing using ultrasonic vibration is performed as a means to implement processing in the ductile mode. We made a comparison with a finish by end mill tool and confirmed an increase in the infeed and the effect of cutting in water on the finish. We performed experiments on cutting the micro reactor under the optimum condition and confirmed that a non-rotational tool could process a hard vulnerable material. The following is a report of this matter.

With excellent properties, high-temperature superalloys have become the main application materials for aircraft engines, gas turbines, and many other devices. However, superalloys are typically difficult to machine, especially for the thread cutting. In this article, an ultrasonic vibration–assisted turning system is proposed for thread cutting operations in superalloys. A theoretical analysis of ultrasonic vibration–assisted thread cutting is carried out. An ultrasonic vibration–assisted system was integrated into a standard lathe to demonstrate thread turning in Inconel 718 superalloy. The influence of ultrasonic vibration–assisted machining on workpiece surface quality, chip shape, and tool wear was analyzed. The relationship between machining parameters and ultrasonic vibration–assisted processing performance was also explored. By analyzing the motion relationship between tool path and workpiece surface, the reasons for improved workpiece surface quality by ultrasonic vibration–assisted machining were explained.
