Manufacturing Engineeirng

Most engineering products, such as smartphones, automobiles and airplanes, are composed of lots of precision parts. The advanced machining technology is essential to manufacture the engineering parts with high precision, high efficiency and low costs. In addition the leading-edge machining technology is desired to generate the future fine products. We are trying to develop the leading-edge manufacturing technology through the studies about grinding, abrasive machining and measurement evaluation in their processes.

High Efficiency Precision Grinding of CFRP

Carbon fiber reinforced plastics (CFRP) has been growing in availability as component parts of airplane. The high efficiency and precision grinding technology of CFRP is developed using the in-process dry ice blasting for prevention of loading.

Precision Abrasive Machining and Surface Characterization for Highly Functional Surface

The fine hard particles (abrasives) interfere in workpiece surface with the motion energy by tools or fluid to remove materials in less than micron size. The machining technology is developed for generation of micro texture or profiles on finished surface with high functions, controlling the interference of abrasive grain. In addition the characterization of the finished surface is developed.

Research on construction of the cutting-conditions decision support system using data-mining

The engineer's manufacturing-support system was established by applying data mining method which is the newest statistics analysis technique to the data group obtained in the tool catalog or experimental data.

Research on highly-efficient processing of difficult-to-cut materials

Establishment of a highly efficient removal processing process of the super alloy and titanium alloy used as a charge of aerospace material and clarification of the removal processing mechanism were performed.
