异型石材制品成形加工的分析研究

Study on Shape Machining of Special-shaped Stones

成形加工是异型石材制品的关键加工工序。在分析异型石材制品的成形面、常用加工工具和成形原理的基础上,对成形加工技术进行了深入探讨,归纳出了异型石材制品加工的运动组合形式,并分析了每种运动组合所能加工的制品种类。成形运动分析为异型石材加工设备功能和结构的开发提供了理论基础。以外圆柱面加工分析为例,得出了刀具形状与加工运动成互补关系的重要结论,这一结论对于异型石材制品的大批量加工具有重要意义,可研制相应的成型刀具,以实现加工的规模经济效益。

The shape machining is the key step of special - shaped stones machining. Based on the analysis of shape, tools commonly used, and shaping principles of special-shaped stones, the shape machining technology of special-shaped stones is discussed deeply, and then all possible motion combinations of the machining of special-shaped stones, as well as products that can be machined by each motion combination are obtained. The analysis of shaping motion of the products provides theoretical basis for the development of functions and structures of special-shaped machining equipments. By taking the analysis of outer cylinder machining as an example, an important conclusion that the tool shape and the shaping motion are of complementary relationship is obtained. This conclusion is important to products with high-volume because the corresponding shaping tools can be developed to machine the products with the low cost of large-scale machining.
