Mastercam是美国CNC公司开发的基于PC平台的CAD/CAM软件，它具有方便直观的几何造型 Mastercam提供了设计零件外形所需的理想环境，其强大稳定的造型功能可设计出复杂的曲线、曲面零件。
Mastercam具有强劲的曲面粗加工及灵活的曲面精加工功能。 Mastercam提供了多种先进的粗加工技术，以提高零件加工的效率和质量。Mastercam还具有丰富的曲面精加工功能，可以从中选择最好的方法，加工最复杂的零件。Mastercam的多轴加工功能，为零件的加工提供了更多的灵活性。
可靠的刀具路径校验功能 Mastercam可模拟零件加工的整个过程，模拟中不但能显示刀具和夹具，还能检查刀具和夹具与被加工零件的干涉、碰撞情况。
Mastercam提供400种以上的后置处理文件以适用于各种类型的数控系统，我厂采用的是FANUC系统，机床为四轴联动卧式铣床。根据机床的实际结构，我们编制了专门的后置处理文件，绳槽曲面加工刀具路径NCI文件经后置处理后生成加工程序。
使用Mastercam 实现DNC加工, DNC（直接数控）是指用一台计算机直接控制多台数控机床，其技术是实现CAD/CAM的关键技术之一。由于本工件较大，处理的数据多，所生成的程序长，数控机床的磁泡存储器已不能满足程序量的要求，这样就必须采用DNC加工方式，利用RS-232串行接口，将计算机和数控机床连接起来。利用Mastercam的Communic功能进行通讯，而不必考虑机床的内存不足问题,经大量的实践，用Mastercam软件编制复杂零件的加工程序极为方便，而且能对加工过程进行实时仿真，真实反映加工过程中的实际情况，不愧为一优秀的CAD/CAM软件。
Mastercam强项在3轴数控加工，简单易用，产生的NC程序简单高效。
主要竞争对手有UG NX，Cimatron, Delcam(Powermill)
诸如CATIA, Pro/E，Solidworks等软件也在CAM方面有长足的进步。
CNC Mastercam is the United States to develop PC-based platform for CAD / CAM software, it is convenient intuitive geometry Mastercam provides the necessary design components form the ideal environment, its strong and stable modeling capabilities to design complex curve, surface parts .
Mastercam strongly rough surface and surface finishing flexible features. Mastercam provides a wide range of advanced technologies rough, spare parts processing to enhance the efficiency and quality. Mastercam also rich in surface finishing, you can choose from the best method, processing the most complex parts. Mastercam multi-axis processing functions, as part of the process to provide more flexibility.
Reliable tool path checking function Mastercam can simulate the entire process of spare parts processing, simulation tool and not only show fixture, the tool can also check with the fixture and processing components to interfere in the collision situation.
Mastercam provide more than 400 kinds of post-processing documents to apply to all types of CNC, I used the plant is FANUC system, 4-axis machine tools for milling machine horizontal linkage. According to the actual machine tool structure, we prepared a special post-processing documents, groove surface processing tool path by the NCI post-processing documents generated after processing.
The use of Mastercam achieve DNC processing, DNC (direct numerical control) refers to the direct control of a computer numerical control machine tools and more, the technology is the realization of CAD / CAM one of the key technologies. As part of this larger, processing of data, generated by the long process, the CNC machine tools magnetic bubble memory has been unable to meet the requirements of procedures, so we must use DNC processing, use RS-232 serial interface, CNC machine tools and computers to link up. The use of Mastercam Communic function telecommunications, machine tools without having to consider the issue of memory, with a lot of practice, with Mastercam software components of complex procedures for processing extremely convenient, but also on the processing of real-time simulation, a true reflection of the actual processing , Deserves to be an excellent CAD / CAM software.
Mastercam strengths in the three-axis CNC Machining, easy-to-use, the NC program simple and efficient.
Major competitors have UG NX, Cimatron, Delcam (Powermill)
Such as CATIA, Pro / E, Solidworks, and other aspects of CAM software also has made significant progress.
