　　　摘要  由于泡沫材料的用途廣泛，全世界材料市場對它的需求量迅速上升。泡沫材料被廣泛應(yīng)用與汽車工業(yè)、食品包裝工業(yè)、醫(yī)療衛(wèi)生、運動器械、家庭用具、海岸浮標(biāo)及救生圈,和小型船只等。因為泡沫材料的使用大大關(guān)系到人們的日常生活，所以有必要通過改變切割和加工的速度使它形成各種不同的形狀。這種利用計算機輔助切割機床或全自動切割機才能達到。但是，切割的速度將會影響到材料加工后的表面粗糙度。所以，為達到優(yōu)質(zhì)的表面加工質(zhì)量，有必要確定聚苯乙烯的表面形態(tài)。當(dāng)前，人們正在研究制造一臺用于這種泡沫材料的快速原型制造設(shè)備，研究的第一階段就是在不同種類的金屬切割絲在不同的溫度下用不同的進給量切削后利用坐標(biāo)測量儀確定聚苯乙烯表面形態(tài)。

　　　Abstract: The market for foam materials has been growing rapidly throughout the world as they have a variety of uses. Some examples are in the automotives industries, food packaging industries, medical application, sports gears, home insulations and floatation in offshore drilling rigs, buoys and small boats. Since the uses of foam affects greatly the daily lives of humans, the need to have foams in different shapes requires speed in cutting and manufacture. This can only be done through computer aided cutting machines or automated cutting of foams. However, the speed of cutting will affect the surface . finish of the cut. Therefore, it is necessary to determine the surface form of the polystyrene to achieve quality results. This is an on-going research to produce a rapid-prototyping machine that cuts foam models. The . first phase of this research is to determine the surface form of polystyrene through the use of a coordinate measuring machine (CMM), after being cut with different types of wires, at different temperatures and cutting feed-rates.
