Hardware and Software Simulator for Two-Axis CNC Turning Machine

General Description of the Product

The simulator is an integrated machine for teaching programming of turning operations with numerical control (CNC), which has an innovative design concept combining a software simulator of a two-axis turning machine and a real numerical control system.

The presence of an original control panel and manual pulse generator (MPG) allows students to work in a single operating environment similar to a real CNC machine during training, laying a solid foundation for practical experience with real machines in subsequent practice.
