Abstract:Different types of cutting tools were used to cut SiC whisker reinforced aluminu m composite. And then the 3 D components of cutting forces Fc, Fp, and Ff were measured with a Kistler 3 D dynamometer, and the microscopic pattern and profiles of the cutting edges and the machined s urfaces were examined with an atomic force microscope (AFM). The results showed that, compared with fixed circular cutters the self propelled rotary carbide to ols had superior wear resistance property similar to that of diamond tools. The tool life had increased more than 60 times with stable cut in and cut out and less oscillation in the cutting process. The machined surfaces showed high qual ity, gray metal shine of the aluminum matrix, smaller surface roughness, and les s broken SiC whiskers and pits. The 3 D cutting force components F c, Fp, and Ff were reduced to some degree. The average radial th rust cutting force Fp had a significant reduction of 30%~60%. The self p r opelled rotary carbide tools were thought to be one kind of tools with low cost and high cutting performance and a suitable tool in machining the composites rei nforced with SiC whiskers of moderate or lower volume fractions. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
