数控基准转换模式在大功率船用低速柴油机零件机架加工中的应用

Application of NC Benchmark Transformation in the Process of Frame of High-power and Low-speed Marine Diesel Engine Part Machining

通过对大功率船用低速柴油机零件机架的工艺分析,结合大型数控龙门铣床对腔体类零件的加工特点,融合刀具、工装及数控编程等多领域技术,形成了一套数控基准转换模式的机架加工方案,其有效规避了大型机床操作工的登高作业风险,使零件加工基准统一,机床加工干涉透明,人机互动简单易控。

Through the process analysis of frame of high power and low speed marine diesel engine＇s part, and combined with large CNC gantry milling machine processing characteristics of cavity parts, cutting tools, fixture and CNC pro- gramming application of many fields, a set of frame＇s processing scheme of numerical control benchmark transformation model was formed, it can effectively avoid the risk for heavy machine tool operators work in height, made unified benchmark of parts machining, machining interference easy to see and control the man-machine interaction.
