The use of methods for generating control programs of the CNC in the manufacture of the Troost screw

Abstract

Companies are facing a growing demand for small-scale production of ship components. This increases the relevance of production systems that optimize the production time of complex products. Automatic generation of individual blocks of CNC programs opens up great opportunities to accelerate and improve the preparation of production of complex and especially small-scale orders, such as the manufacture of Troost screws of various configurations. This study is devoted to the creation of blocks of CNC programs based on the parameters provided by product configuration systems. Various approaches to the pre-production process are described and characterized. It is shown that the direct transfer of parameters to the CNC program can be fully automated, but is limited by the geometry of the manufactured part, which can be obtained using parametric processing cycles. In order to determine the most appropriate procedure for generating a program for a specific case, a solution methodology was developed. An approximate implementation is presented, showing the possibilities of automated generation of CNC programs in the production of Troost screw parts. It is established that when choosing the optimal method of generating a program for a CNC machine in the manufacture of a Troost screw, the amount of ROM memory required can be reduced by 10.86 times. The processing time is reduced by 1.07 times, or 39 minutes
