中文译文
计算机控制程序员与操作员该做什么(中文5800字,英文3800字)
计算机控制的程序员和操作员使用电脑数值控制（CNC）机器切割及形状精度的产品，如汽车配件，机器零件和压缩机。数控机床，包括加工工具，如车床，铣床，多轴主轴，电火花机（EDM），但人类操作员以前所完成的功能是由计算机控制模块执行。CNC机床切去材料从固体块的金属，塑料，或玻璃，被称为的工件，以形成成品零件。计算机控制的程序员和操作员通常产生大量的其中一部分，虽然他们可能会产生小批量或单件物品。他们用的金属及其与数控编程设计和实施需要加工，满足精确规格产品的操作技能的工作性质的认识。
数控程序员，之前也被称为数字工具和过程控制程序员机器的一部分，他们必须仔细规划和准备操作。首先，这些工人审查三维计算机辅助/自动化设计（CAD）的部分蓝图。接下来，他们计算出在哪里削减或钻入工件，如何快速养活金属进入机内，又有多少金属去除。然后，他们选择的工作和计划的切割和修饰操作序列的工具和材料。

英文原文
What computer-control programmers and operators do
Computer-control programmers and operators use computerized numerical control (CNC) machines to cut and shape precision products, such as automobile parts, machine parts, and compressors. CNC machines include machining tools such as lathes, multiaxis spindles, milling machines, and electrical discharge machines (EDM), but the functions formerly performed by human operators are performed by a computer-control module. CNC machines cut away material from a solid block of metal, plastic, or glass-known as a workpiece-to form a finished part. Computer-control programmers and operators normally produce large quantities of one part, although they may produce small batches or one-of-a-kind items. They use their knowledge of the working properties of metals and their skill with CNC programming to design and carry out the operations needed to make machined products that meet precise specifications.

Before CNC programmers-also referred to as numerical tool and process control programmers-machine a part, they must carefully plan and prepare the operation. First, these workers review three-dimensional computer aided/automated design (CAD) blueprints of the part. Next, they calculate where to cut or bore into the workpiece, how fast to feed the metal into the machine, and how much metal to remove .They then select tools and materials for the job and plan the sequence of cutting and finishing operations.
