In sawing operation of synthetic jewelry, the performance of diamond cutter blade is very dependent on the blade variables. This investigation presents ecperimental results which show the effects of the blade variables such as types of diamond abrasives, grain size of diamond, concentration, and bond materials on the beavior of te blades. Based on the experimental results an optimum blade condition for the sawing of cubic zirconia was recommended.

A theoretical analysis is presented on the mechanics of diamond blade sawing. Experimental results are also presented, which show the effects of cutting variables such as cutting speed, feed speed, cutting area, and concentration of deamond blade on the cutting forces. The analytical results aggreed well with experimental ones.

A theoretical analysis is presented on the mechanics of diamond blade sawing. The normal and tangential components of cutting force are calculated. Experimental results are also presented, which show the effects of cutting variables such as cutting speed, feed speed, cutting area, and concentration of diamond blade on the cutting forces. The experimental results are found to be in good agreement with those predicted by the analytical calculation.

PURPOSES: In this study the influence factors related to abrasion resistance of interlocking concrete block have been evaluated, and comparisons between various domestic and foreign abrasion test methods was also accomplished. METHODS: The modified rotational cutting method suggested in ASTM C 944 was applied. Surface materials with different types of fine aggregate such as crushed sand, sea sand, and mixture of crushed and sea sand were tested to compare the aggregate effect for abrasion resistance. RESULTS: The different surface mixtures with various W/C ratios, mortar and fly ash ratios have been investigated for functional and economical considerations. CONCLUSIONS: This study had obtained reliable results by changing diamond blade of rotating cutter. Therefore, in order to improve the abrasion resistance of interlocking concrete block for road, a new mix design was proposed.
