摘　　要：在新的数控编程接口标准ISO14649(即STEP-NC)下,提出了一种在加工前进行零件可加工性评价的数控机床信息模型,目的是实现STEP-NC数控程序的加工不依赖于具体的数控机床。通过分析STEP-NC程序对零件加工工艺的描述,得出STEP-NC程序对机床信息的要求在此基础上建立了基于STEP-NC数控程序可加工性评价的数控机床资源信息模型,从而实现了数控机床资源信息对STEP-NC数控程序需求的完备性和透明性,为进行STEP-NC数控程序针对特定数控机床的可加工性评价奠定了基础。To implement machining parts without selecting the specific NC machine tools as long as the NC programs of parts are generated according to ISO14649,a CNC machine tool model based on evaluation of part manufacturability is proposed.By analyzing the process description in STEP-NC files,the requirements for machine tools can be obtained,which include six aspects such as table,spindle,feed speed,locating precision,cutting tool,and auxiliary devices.Based on the above analyzing,a CNC machine tool information model is established. This information model is fundamental to evaluate the manufaeturability of a part on a specific machine tool.
