Matters concerning design

To perform control (data change, operation status change, etc.) on an device and equipment (numerical

controller, PLC, servo, robot, server, etc.) that is in operation from an industrial personal computer equipped

with this product, configure an interlock circuit outside the device and equipment so that the entire system

always works on the safe side. Read the manual thoroughly and make sure it is safe before proceeding. In

particular, the above control for device and equipment from a remote location via a network may not be able

to immediately deal with troubles on the device and equipment side due to abnormal data communication.

Provide a safety circuit outside the industrial personal computer so that the entire system works safely even

if the industrial personal computer equipped with the product fails. Accidents may occur due to incorrect

output or malfunction.

Matters concerning design

While various settings are reflected, do not perform the operation that forces the power of the industrial

personal computer equipped with this product to be turned OFF. If you perform an operation such that the

industrial personal computer equipped with this product is forcibly turned OFF during the reflection, the data

becomes unstable and it needs to be reconfigured and re-reflected. It may also cause the product to

malfunction.

To protect availability, integrity and confidentiality of the system against cyber-attacks including

unauthorized access, denial-of service (DoS) (*1) attack, and computer virus from external sources via a

network, take security measures such as firewall, VPN, and anti-virus software.

(*1) Denial-of service (DoS) refers to a type of cyber-attack that disrupts services by overloading the system

or by exploiting a vulnerability of the system.

Mitsubishi Electric assumes no responsibility for any problems caused to the system by any type of cyber-

attacks including DoS attack, unauthorized access and computer virus.

Matters concerning operation

The simulation result does not guarantee the machining accuracy of the actual NC.

1. Overview

IB-1501743-A

1. Overview

NC Virtual Simulator enables simulation from various angles digitally (on a PC) using the same machining conditions as used by the actual machine tool. It simulates the motion of the CNC realistically, including smoothing, acceleration/deceleration and delay in servo response. It provides highly-accurate simulation because the same machining conditions as used by an actual machine tool can be used. It helps you to detect the problems before actual machining including machining errors, faulty setup, and machine interference, which you were previously not able to identify until trial machining. This increases your work efficiency and productivity.

(*1) CAD: Computer Aided Design (*2) CAM: Computer Aided Manufacturing (*3) CAE: Computer Aided Engineering NC Virtual Simulator offers the following two main functions.

Machining simulation Realistic simulation of the motion of the CNC using the same machining conditions as used by the actual machine tool. You can check a highly-accurate graphic representation of the workpiece contour, the calculated machining time, and machine interference. It allows you to detect machining errors and faulty setup before actual machining, which was not possible with the simulation using CAD/CAM tools.

Analysis simulation Simulation that allows visualization of positions and change in feedrate and acceleration, etc. at a micro segment level using color maps or other means. It makes it easy to recognize and analyze what caused slight surface blemishes.

(*) The current version only supports CNC for machining center with a single part system.

8. Tool settings 8.3 Caution

IB-1501743-A

8.3 Caution

Since R offset "D" cannot be specified when compensation type I is selected, the tool radius is not set in the tool radius offset. To change the tool radius offset, change it in the NC Data List sub-display.

When compensation type II is selected, ensure that the length and wear amount of the shape are taken into account in the offset values of L offset "H" and R offset "D". You cannot set the wear amount only. To change the wear offset , change it in the NC Data List sub-display.

If there are duplicate offset numbers, it causes unintended simulation because the offsets for the duplicate tool are changed when the tool length or tool radius is changed, which results in inconsistency between the tool length and tool radius and the offsets.

(1) Only parameters changed in the sub-display "NC Data List" are displayed in the machining conditions of the history displayed in the sub-display "Simulation History". Parameters changed by G10 command are applied to the sub-display "NC Data List", but are not applied to the machining conditions of each history displayed in the sub-display "Simulation History".

(2) Simulation histories that can be displayed on the right and left screens are those where both file path and file name of the machining program used for simulation are the same. When contents such as the line number in the machining program and G code are different but both file path and file name of the machining program are the same, the simulation history is to be displayed on two screens. Therefore, the machining program displayed in the sub-display "Display program" may be inconsistent.

(3) Simulation histories to be saved after simulation and settings to retain the simulation histories do not depend on whether the project is saved but are updated accordingly.

11. Caution

11. Caution

Please keep in mind the following considerations related to NC Virtual Simulator. You cannot open more than one NC Virtual Simulator at the same time. You cannot run NC Virtual Simulator and another user support tool (e.g., NC Trainer, NC Trainer2 plus, NC

Explorer) simultaneously.

The result of a floating-point operation may differ between NC Virtual Simulator and the NC unit within a range of rounding error. (The floating-point operation of NC Virtual Simulator is the same as that of the CPU of the PC.)

If a symbol other than "." is specified as the decimal separator on Control Panel, you may not be able to open or save projects successfully. To change the decimal separator, select [Start] > [All apps] > [Windows System Tool] > [Control Panel] > [Clock and Region] > [Region], and click [Additional Settings] button to display "Customize Format" dialog.

Please keep in mind the following considerations related to the machining programs to simulate on NC Virtual Simulator. Subprograms that can be called by M98 command are those stored in the same folder as the main

program, in NC memory and in NC memory 2. As for NC memory and NC memory 2, the subprograms can be called only when NC memory and NC memory 2 are set in the parameter (#8880 or later) for the subprogram storage location. To call a subprogram stored in the same folder as the main program by M98 command, call it without specifying ",D" (device number for subprogram). To call a subprogram stored in NC memory or NC memory 2 by M98 command, specify the device number set in the parameter (#8880 or later) for the subprogram storage location, to ",D".

Programs on NC memory such as subprograms called by G65 command and M code macros cannot be called unless they are contained in machine tool's backup data imported to the project.

G54.4 Workpiece installation error compensation function is not supported. When it is commanded, the program error (P34) occurs.

Machining condition selection cannot be used in a sample project.

12. Troubleshooting

The following describes common problems related to NC Virtual Simulator and how to troubleshoot them.

12.1 Machine model is not displayed

If the machine model is not displayed when you run machining simulation, try the following: (1) Open the xml file in the machine folder under the project folder (*1), and verify the file name of the geo

tag (geo=. stl). (*1) The project folder is the project name folder under the project storage folder (default

"C:\MELCNC\NCVS\Project"). (2) Verify that all stl files checked in (1) are in the machine folder. (3) If any file is missing, contact the machine tool builder and obtain the machine model again.

12.2 Simulation takes time depending on PC

If the graphic board of the graphics processor (GPU) mounted on the PC is not correctly recognized, or if the version of the driver is old, simulation may take time. This may be improved by the following steps.

12. Troubleshooting 12.4 Machining condition selection in [NC Data List] cannot be used

IB-1501743-A

12.4 Machining condition selection in [NC Data List] cannot be used

Machining conditions in the [NC Data List] sub-display may not be able to be set. Even if a value other than "P0" is selected in [Machining cond] of [Tolerance ctrl], the value returns to

"P0". If values are entered in the parameters "#1206 G1bF" to "#12070 Sfilt2_tol" of [Machining cond P1-Q1] to

[Machining cond P3-Q3] and the [Enter] key is pressed, the sub-message "This value cannot be set." appears and the values cannot be set.

These occur for a project created from a machine tool where the machine condition selection is disabled. Create a project after executing [Execute init.] on the machining condition setting screen of the machine tool.

12.5 Macro alarm message appears during simulation and simulation stops

If macro call of miscellaneous command (macro call of M, S, T, B codes) is performed while a machining program is running, "P422 macro alarm message" may appear and simulation may stop. In this case, check [Disable macro call] of [Simulation priority] in the "Machining simulation settings" or "Analysis simulation settings" sub-display, and then run the machining program again.
