Numerically controlled (NC) machining has and will continue to enhance manufacturing productivity by yielding final products with high reliability and high precision. NC machines are driven by computer programs that are usually written by available shop personnel. Generation, correction, and verification of NC code are time-consuming tasks. Computer-assisted NC coding software is available, but with limited capability. Currently, there exist only weak links between computer-aided design (CAD) systems and NC machining. The ideal is a fully integrated system wherein the NC code is generated automatically from a CAD-generated part specification. There is a strong need to provide an economical and efficient means to verify the correctness of an NC program and to provide automatic generation of NC programs from a CAD database. Microcompatibles proposes to apply a novel solid modeling method to the problem of automatic NC code generation and verification. They will create an efficient and economical mechanism to generate 3D graphical emulation of NC machining providing dimensional information, checks for undesired tool, spindle, fixture, or workpiece collisions, and automated verification capability. This is a small business Innovation Phase I award.

数控加工已经并将继续 通过生产高质量的最终产品来提高制造生产率 可靠性高、精度高。 数控机床由计算机驱动 通常由可用的车间人员编写的程序。 NC代码的生成、修正和验证是非常耗时的 任务 计算机辅助NC编码软件可用，但 能力有限。 目前，只有薄弱环节， 计算机辅助设计（CAD）系统和数控加工。 理想是 完全集成的系统，其中自动生成NC代码 从CAD生成的零件规格。 迫切需要 提供一种经济有效的方法来验证 一个NC程序，并提供从一个 CAD数据库。 Microcompatibles提出应用一种新的实体建模方法 数控代码的自动生成与验证问题。 他们 将创建一个高效和经济的机制来生成3D 提供尺寸信息的数控加工图形仿真， 检查不希望的刀具、主轴、夹具或工件碰撞， 和 自动化验证能力。 这是一个小企业创新 第一阶段奖励。
