Abstract
Computer-aided manufacturing involves a set of computerized activities related to the preparation, launch and follow-up of manufacturing. Computer-aided manufacturing is a tool that allows the use of 3D models based on computer-aided design. This paper addresses the process of rotational formation, with an effective focus on the technology of processing a rotational mold using CAM simulation as a research method. In this sense, the right choice of CNC and cutting tools is essential. The use of numerically controlled machine tools and high-performance cutting tools reduces the number of operations. The manufacturing route realized is specific to the parts machining on numerical control machine, with multiple possibilities such as the execution on a single machine of all the necessary operations to create the mold. PowerMILL gives the user the flexibility to generate thisheir NC programs and ensures the use of the most efficient processing method without having to wait for the complete calculation. A number of different strategies, from the wide range that PowerMILL has, are compared using a high tolerance so that they can be calculated quickly. In this study, the strengths of the CNC are highlighted based on experimental research, features that make this machine a very productive one, saving time, energy and, implicitly, low execution costs.
Highlights
Rotational forming is superior to other processing methods in terms of low cost, break-even point and size of parts that can be manufactured

In authors opinion the process of rotational molding is superior to other processing methods in terms of costs, as they are much lower
Summary
Rotational forming is superior to other processing methods in terms of low cost, break-even point and size of parts that can be manufactured. Often products made by rotational forming are a substitute, with a lower mass, for traditionally used materials [1]. The concept of rotational formation is older than 150 years, the production of hollow plastic parts for various applications (such as play equipment, furniture, tanks and canisters, etc.) has been used only for the last 50 years [3]. The molds required for the rotational forming process can be obtained from several types of materials and can be made by several methods [6]. Among the methods of obtaining and the types of materials of the rotational molds, we can mention: The CNC program is nothing more than a series of orderly instructions that the machine controller executes sequentially, step by step [16]
