Read full description

CNC Lathe Simulator is a software simulator of a numerical control lathe is an educational methodological development intended for basic familiarization of novice machine building specialists with the principles of programming parts turning operations using standard G-code (ISO). The three-dimensional simulation model is based on a lathe with an inclined bed, equipped with a CNC system, a twelve-position turret head, a three-jaw chuck, a tailstock, a system for supplying lubricating and cooling liquid, and other units. The material is processed along two controlled axes. Field of application of the software product: educational process using computer technology: laboratory lessons of students in computer classes, distance learning, demonstration support of lecture material in the group of areas of training and specialties: «Metallurgy, Engineering and Material Processing». The main functions of the application: editing the code of control programs of a lathe, operations with control program files, setting up geometric parameters of a cutting tool, continuous/step-by-step execution of control program blocks, three-dimensional visualization of tool movements in the machine’s workspace, simplified visualization of the workpiece surface, calculation of processing modes, a brief reference guide on using G-code. https://sunspire.site/terms_of_service.html
