Uso do software CAM em auxílio a estimativa de custos de fabricação na fase inicial do desenvolvimento de produtos poliméricos injetados

Abstract

In the current context of the industrial sector where competitiveness is increasing, reducing the uncertainties present during the development of new products becomes essential. For this reference model of the PDP, which aim to improve the design, facilitating their development and reducing uncertainty can be used. Some industries require large initial investment for the production of the product and may highlight the polymer injection. In this process, there is an initial purchase of injection mold, which is responsible for a large portion of the final cost of the product, which is essential to carry out the step. Seen that the use of tools that may reduce the uncertainties become very valuable. One of these tools is the CAM software, which is routinely used in the stages of detailed design and production preparation. Use it for non-traditional way, aid in the cost estimate, since in the early stages of the PDP can bring some advantages to the project development. Thus, we seek to identify the contribution of CAM software tool to aid in estimating costs for decision-making early in the development process injected polymer products. To conduct the study sought to evaluate the early stages of the reference models of the PDP in order to identify activities as essential given the process. With the identification of the phases of CAM, software features, which assist in performing the activities in the initial phase of the PDP, were correlated. With this proposed a methodology for estimating the costs of manufacturing injection mold for the initial phase of the PDP. Then performed a case study, varying the design of the product, in which we attempted to identify the contribution of CAM software in estimates of manufacturing costs. After the completion of the case study, it can be seen that the CAM tool can assist in the initial design stage, because it favors the selection of the design of the product being manufactured, as it can be through the CAM software to estimate the times and machining tools needed to manufacture the injection mold. Note also that this tool favors the definition of the product portfolio by estimating costs for mold manufacturing.
