Why EMS Virtual CNC?
What can it do for me?
Running a profitable manufacturing shop floor is challenging.  And keeping it productive is tough work.  Those that succeed embrace technology. Over 1000 manufacturers and job shops rely on EMS Virtual CNC to keep their CNC machines running reliably while minimizing errors.

• Eliminate expensive mistakes.

• Proveout processes offline

• Simplify CNC Setup

• Minimize waste

• Organizes release to shop floor process

• Gets started quickly and easily

Performing off line simulations has many, many other benefits including:

Increase Productivity - off line simulation frees your machines to run jobs that are making you revenues, not costing you profits...

Maximize Resources - off line simulation adds to tooling life, saves coolant for "real" jobs, reduces "wear and tear" on expensive machine tools, and much more...

Ensure Quality - verify surface finish, feature dimensions, cutter path, tool and holder clearance, gouge checking, and more...

Milling - 2, 3, 4 & 5 Axis
EMS Virtual CNC supports all standard milling machine configurations with 3 to 5 driven axes. User definable machine tool configurations with our flexible reverse post processors allows standard VMCs and HMCs to be supported. Standard milling and drilling cycles are all supported.

NOTE: Advanced milling features include sub programs, macros, variables, expressions, loops, and branching are all supported..

Turbo Milling
Make molds or dies? EMS Virtual CNC's Turbo Milling technology is optimized for 3-axis surface machining. Processing times are often many times quicker than competitive technologies, while retaining the accuracy that you would expect.

NOTE: Turbo Milling can process 10,000 to 40,000 blocks of G code per second on Pentium P4 based PCs.

4 and 5 Axis Simultaneous Milling
Make complex parts? EMS Virtual CNC fully supports simultaneous 4 and 5 axis machining. Optionally, you can define your entire machine for full collision detection of any moving part.

NOTE: Support for rotary heads, rotary tables, nutated heads, nutated tables and multiple spindles are all supported.

Turning - 2 Axis
Have CNC Lathes? EMS Virtual CNC supports 2-axis turning applications. User definable machine tool configurations combined with our comprehensive library of reverse post processors allows standard HTLs and VTLs to be supported.  Standard lathe facing, turning, threading, grooving, roughing and drilling cycles are all supported.

NOTE: Advanced turning features include sub programs, macros, variables, expressions, loops, and branching are all supported.

Turbo Turning
Need to inspect lathe parts? EMS Virtual CNC's Turbo Turning technology is optimized for 2-axis lathe parts that support fast and easy inspection.

Solids based technology - EMS CMS Modeling.
EMS Virtual CNC is based on our internally developed solid modeling technology called CMS Modeling.. CMS Modeling has been developed over the last 20 years for the specific purpose of CNC machine simulation and verification. CMS Modeling provides numerous benefits vs. the popular solid modeling kernels one finds within CAD/CAM software.

G and M Codes Support via Configurable Reverse Post
Have a variety of CNC machines? EMS Virtual CNC includes 100+ reverse posts to get you started.  A 200+ page reverse post manual documents all of the options available to support a wide range of CNC machines.  Specific reverse posts to each of your machines can also be purchased.

APTCL Support
Need to verify APTCL? EMS Virtual CNC supports several flavors of APTCL formats from the leading CAM systems.  APTCL is supported just like G & M codes and extensive customization is possible via the reverse post.

MasterCAM Support
Need to verify MasterCAM tool motion? EMS Virtual CNC directly supports NCI files.  In addition, a C-hook is included that will automatically transfer all appropriate stock and tooling definitions from MasterCAM directly into EMS Virtual CNC.

SurfCAM Support
Need to verify SurfCAM tool motion? EMS Virtual CNC directly supports INC files.

Error Detection
Want to minimize mistakes? EMS Virtual CNC detects programming and postprocessor errors before they can cause disruption on the machine shop floor. EMS's Virtual CNC Error Log even allows you to directly edit the exact line of code where the error occurs using the included EMS Editor. The following errors are detected:

• CNC Program Syntax Errors

• Rapid Travels Into The Part

• Tool Shank Collisions

• Tool Holder Collisions

• Tool Collisions With Fixtures And Clamps

• Gouge Detection

Part Inspection prior to Machining
Want to verify that the right thing will happen on the shop floor?EMS Virtual CNC provides animated simulation of the machining process. Seeing how the tool behaves under program control provides great reassurance that there are no gross errors in the program and makes the cause of smaller errors easier to diagnose. Rapid zoom, rotate, pan and cross-sectioning of solid model views allows errors to be seen, even if they are hidden from the original view or are inside the part.

Feature Inspection
Need to inspect parts? EMS Virtual CNC includes feature based inspection and virtual CMM (Co-ordinate Measuring Machine) inspection capability. Feature based inspection uses the CMS feature recognition capability to measure feature dimensions and the relationship between separate features. EMS Virtual CNC recognizes edges, arcs, cylinders, planes and cones. To select a feature, all you need to do is click on the feature using the mouse cursor.

CMM Inspection
EMS Virtual CNC's - Virtual Coordinate Measuring Machine. (CMM) provides point inspection for complex surfaces. Using the mouse cursor as the CMM probe, the user can select any point on a surface and get the co-ordinates for that point. Entering multiple points allows the relationship between points to be measured. Keyboard input of precise X-Y co-ordinates returns precise Z values for that point.

CAD Compare
Need to machine within tolerances? EMS Virtual CNC includes an option to compare the machined part back to the designed part within any tolerance. Users can define a tolerance above and below which excess  material and gouges are shown. The tolerance can be adjusted at any time without reprocessing the job. Using EMS's STL Compare. capability in conjunction with CMM inspection allows deviations from the design model to be measured at any point on the part surface.

Advanced Tooling
Have complex tooling? EMS Virtual CNC includes support for 10 standard milling tool types and 10 standard turning tool types.  Custom tool shapes, custom tool shanks, and custom holders are all supported.  An unlimited number of tool libraries provides tool kits per machine, per customer, etc.

Complex Stock and Fixtures
Machine castings? Use complex fixtures? EMS Virtual CNC supports 10 standard stock and fixture shapes.  Complex stock and fixtures can be importing via STL files.  Full collision detection is supported for chucks, jaws, face plates, tail stocks, tombstones, pallets, clamps, vices, etc.

EMS API and ActiveX Development Platform
Want to integration EMS Virtual CNC within your own application? EMS Virtual CNC includes an open development and comprehensive API (application programming interface) with 300+ methods all fully documented.  Even easier is an ActiveX control that you can drop into your existing project.  Several source code examples are available and you have the flexibility of using C++, VB, VB script, Delphi and other compatible programming languages.
