【 摘 要 】

In this study, parameters that effect metal cutting process of cast PA6G (Castamide) material whose usage area in machine design and production has been increasing is investigated. Castamide is an engineering plastic whose mechanic strength values are high, durable towards corrosion and suitable for metal cutting. However due to the physical feature of the material; it has the feature of water absorbing in about 7% rate. The amount of water in castamide materials influences the processability of the material and average surface roughness. The average surface roughness values of dry and humid castamides that is under same conditions wants to be observed, the best cutting conditions were detected. Therefore, the parameters of cutting speed, feed rate and depth chip changed in defined for conditions. Experiment showed that the amount of humidity in castamide materials is an important factor for average surface roughness.
