  • Machined surface visualization
  • G-code reference guide
Features
Read full description

The CNC milling machine simulator is a multimedia application designed to provide a basic introduction to beginner mechanical engineering professionals with the principles of programming operations for milling parts using a standard (ISO) G-code. The main task of the application is syntactic analysis (parsing) of the code of control programs in order to build a graphical model of cutting tool trajectories in three-dimensional space. The main functions of the application: editing the code of the control programs of the milling machine, operations with files of control programs, setting the geometric parameters of the cutting tool, continuous/step-by-step execution of blocks of control programs, three-dimensional visualization of tool movements in the working space of the machine, simplified visualization of the machined surface of the part, calculation of processing modes, a quick reference guide to using G-code. The main limitations of the application are: low accuracy of cutting surface modeling, the impossibility of using polygonal geometry as a workpiece, a simplified model of machine tooling elements.

Verdict

The call

Trigonometry calc and CNC VMC Simulator both sit at 3.0 stars, but that hides the real split: 48% of CNC VMC Simulator's written reviews are positive against 0% of Trigonometry calc's. CNC VMC Simulator also leads on in-app purchases (none vs 1) and ads (none vs shown). Trigonometry calc's advantage is price (Free vs $6.99). On rating, update cadence, device support and iOS requirement there is nothing between them.
