5种方法来简化CNC新人的任务

Many manufacturing companies are facing the same challenge: seeking new hires from a dreadfully depleted candidate pool. Sometimes, companies give up on finding and hiring skilled manufacturing people, and focus on finding people who simply show aptitude for learning and a willingness to work.

Since this kind of new hire is typically not prepared to hit the ground running, companies must find ways to bring them to a level at which they can proficiently perform their assigned tasks. So how can manufacturers train new hires without CNC manufacturing experience? I have always said that there are two ways to deal with proficiency issues: training and task simplification. Training brings a person to a higher level; people gain the proficiency required to perform complicated tasks. Simplifying tasks, by comparison, lowers required proficiency; less skilled people can perform simplified tasks. Here, we will concentrate on task simplification, providing five CNC-operator-specific suggestions.

1.）提供操作程序

New CNC operators often learn machine-related procedures by watching them being done. An experienced person performs the procedure with the newcomer looking on. While new CNC operators will eventually learn procedures that are demonstrated (many times) in this manner, experienced operators can save a lot of time, effort and questions by providing step-by-step instructions for common machine-operation tasks. Procedures must still be demonstrated and practiced, of course, but at least newcomers will have something to reference, which will minimize how often they need to ask experienced people for help.

2.）匹配机加工表面以相关尺寸调整

This suggestion applies to all CNC operators, but is especially important for newcomers to the CNC environment. Sizing adjustments are done regularly to keep machined surfaces within their tolerance specifications. Some type of抵消通常用于制作大小调整，并且使用的寄存器的偏移数通常被绑定到切割工具的站号。例如，如果工具＃1计算机表面，例如，偏移＃1将用于调整它。

Setup people (who load cutting tools and size in the first part) obviously know which cutting tool machines each workpiece surface. But after setup, the job is often turned over to a CNC operator. Since the operator did not load the cutting tools, they will not know which offsets are related to each workpiece surface being machined.

通过一种或另一个方式，简化CNC运算符将所需的内容与控制其尺寸的偏移数相提并论。不要让它们弄清楚哪种切割工具临界表面。相反，提供一个标记的绘图，示出了各种机加工表面，可能以不同的颜色，每个颜色表示不同的偏移数。

3.) Provide variable gauges with digital displays

常见的变量仪（包括微米和卡钳）通常用于对施胶调整所需的测量进行测量。虽然商店人民最终应该学习如何阅读所有类型的变量计显示，包括数字，拨号和游标，开始简单。入门级运营商将有足够的问题，了解如何保持变量计并在进行测量时应用适当的压力。通过在显示器上启动仪表，请不要将任务进一步复杂化任务，以显示它们将无法读取。

4.) Provide all required tolerance values

至少有三种方法来指定尺寸公差。以下是所有指定相同的公差的三个例子：

• 加上/减去指定的公差金额：5.000 +/- 0.005
• 高/低限制：5.005 / 4.995
• Plus one value minus another: 5.003 +0.002, -0.008

当然，CNC运营商必须能够进行测量，然后确定测量值是否在其容差频带内落入。如果没有，或者如果它危险地接近公差限制，则需要进行大小调整。当需要大小调整时，CNC运算符必须能够确定测量值与目标值之间的偏差（通常是公差的平均值，但不总是）。

除偏差值外，确保CNC运算符不必计算任何所需值。为它们提供高度和低限制，以及需要尺寸调整的每个表面的目标值。

5.) Explain company-specific terminology and unwritten rules

Each company has its own way of naming and describing its departments, products, part families and processes. This kind of colloquialism makes it difficult for newcomers to get familiar with their new work environment. Part of any company’s new-hire orientation must be to adequately describe those things that make the company unique.

此外，大多数公司都有一定的无证规则和政策，这些规则和政策预计应该知道并坚持。一个常见的例子与工具偏移相关：在许多公司中，任何切割工具的主要偏移编号都与工具站号相同。虽然在生产运行文档中可能未指定偏移量，但CNC人们只是预计会知道这一点。确保在文档中没有明确指明的任何此类规则或期望更新新员工，这些规则或期望将伴随着其工作的作业。
