These have reduced profitability by increasing overheads expenses. If the CAD/CAM system functioned properly, the safety inspection, quality control, etc. could have been done in a simulated environment with the help of designs.
In general, CAM teams carry the elimination of operator errors and reduce labor costs. However, consistent accuracy and optimum use of equipment provide even greater benefits. For example, blades and cutting tools wear out more slowly and get ruined less frequently, which further reduce manufacturing costs. Against this saving, the higher costs of capital goods or the possible social implications of maintaining productivity with a reduced workforce can be argued. CAM equipment are based on a series of numeric codes stored in computer files, which control the manufacturing tasks. The Computer Numerical Control (CNC) is obtained describing the operations of the machine in terms of special codes and geometry of shapes of the components, specialized computer files or creating part programs. The creation of these programs of parts is a task that largely takes place today by special computer software that creates the link between CAD and CAM systems (Sharman, 2003). In case of JM, the software is not functioning properly and is making the system less effective than it needs to be.
这些有盈利能力的下降，通过增加的开销费用。如果CAD／CAM系统功能正常，安全检查，质量控制，等等。可能是在一个模拟的环境设计的帮助了。
在一般情况下，凸轮组进行操作误差的消除和降低劳动成本。然而，一致的精度和设备的最佳使用提供更大的利益。例如，刀片和刀具磨损的更慢，会毁掉较少，从而进一步降低制造成本。在这种节约，成本更高的资本货物或可能产生的社会影响与减少劳动力维持生产率可以说。凸轮设备是基于一系列的数字代码存储在计算机文件中，它控制的制造任务。电脑数值控制（CNC）得到描述特定的代码和组件的形状的几何条件的机器操作，专门的计算机文件或创建零件程序。这些程序的部分创作是一个任务，主要发生在今天由专用的计算机软件，创建CAD和CAM系统之间的联系（沙曼，2003）。在JM，软件不能正常运行，使系统比它需要较少的能。
