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

The clearest difference is price: PLC AI at Free against CNC VMC Simulator's $6.99. PLC AI also leads on rating (4.5 vs 2.9) and update cadence (every 3 weeks vs every 3 months). CNC VMC Simulator's advantage is in-app purchases (none vs 16) and review sentiment (48% vs 29%). On ads, device support and iOS requirement there is nothing between them.

PLC AI is free to download; CNC VMC Simulator costs $6.99 up front. PLC AI sells 16 in-app purchases, starting at $4.99 per 7 days. CNC VMC Simulator asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

PLC AI holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: PLC AI has 75 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 48% of CNC VMC Simulator's written reviews are positive against 29% of PLC AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CNC VMC Simulator ships an update every 3 months, PLC AI every 3 weeks. The most recent releases landed on September 23, 2026 and August 27, 2026 respectively.
