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.
