About VERICUT

Since 1988, CGTech’s VERICUT software for computer numerical control (CNC) simulation has become the industry standard for simulating CNC machining. The software helps to detect errors, collisions, or areas of inaccuracy. 

It is used by companies of all sizes, universities, and trade schools, as well as government agencies in more than 55 countries globally. Using VERICUT as a CNC simulator enables users to reduce their dependency on manually proving-out NC programs from new machinery. It can also help to reduce wastage. The program also optimises numerical control (NC) programs to save time and produce a higher-quality surface finish. 

VERICUT simulates all types of CNC machine tools, including those from leading manufacturers such as Mazak, Makino, DMG / Mori Seiki, or Okuma. VERICUT runs standalone but can also be integrated with all leading computer-aided manufacturing (CAM) systems.

VERICUT Verification

VERICUT is a 3D solids-based CNC simulation software program that simulates the material removal process of an NC program. The program depicts multi-axis milling, drilling, and turning, as well as combination mill and turn machining.  

 

Feed Rate Optimization

VERICUT is equipped with optimisation capabilities which use programming to automatically determine an optimum safe feed rate. Optimised feed rates also result in longer cutting tool life, fewer broken tools, and better-quality parts.  

CNC Machine Simulation

The VERICUT CNC simulator shows material removal at the workpiece level. However, it can also simulate entire machines and machine tool components, as they would appear on a shop floor. The simulation flags collisions and near-misses between all kinds of components. 

 

 

Check out a few of the advanced machine features that VERICUT supports

CNC control features which rotate or define 3D coordinate systems and offsets

Some newer CNC simulators provide transformation routines that enable the NC program to be independent of the machine’s physical configuration. These features require VERICUT to read the NC program and do the same transformation to move the "virtual axes." Some of these complex transformations establish a new secondary coordinate system, such as TRANS, ROT, ATRANS, and AROT on the Siemens 840D control, or CYCLE DEF 19.1 on the Heidenhain TNC control. 

 

Some transformations allow programming in a virtual “workpiece” coordinate system, such as TRAORI on the Siemens 840D control, or M128 on the Heidenhain TNC control. Other control transformation features enable work offsets to dynamically adjust axis positions based on rotary axis positions, such as Fanuc’s G54.2. 

Automatic part transfer between fixtures

Machine tools that automatically transfer the workpiece from one fixture or machining station to another, such as between the main spindle and sub-spindle of a lathe, require a more complex simulation. 

VERICUT CNC simulation software can also simulate the automatic transfer of the machined stock between fixtures. In turning operations, the stock can be divided into two pieces, such as when a piece is clamped in a turning centre's sub-spindle and cut-off. 

Index® mill/turn machining center’s multi-channel programming & synchronization

The Index mill/turn machining centres use a unique programming approach to control and synchronise different axes groups, called “channels.” Index’s multiple channels are programmed using a main program which calls sub-programs for each channel. In the VERICUT simulator, the axes for each sub-system are driven by a sub-program. This sub-program is also synchronised with another sub-system.  

Facing head (or “programmable boring bar”)

A facing head is a milling machine head or spindle attachment containing a programmable linear axis perpendicular to the spindle axis. A facing head is usually used on large horizontal machining centres, such as machines from Giddings & Lewis, DS Technologies, Ingersoll, Waldrich Coburg, and others. The tool attached to the facing head is a single point turning tool or boring bar. Simulation of the facing head motion requires VERICUT to spin all components connected to the spindle and remove the material with the spinning tool. 

CNC controls which allow programming of the tool axis using IJK tool axis vectors

Some new CNC controls allow programming a machine tool’s rotary axes by specifying the cutting tool’s orientation relative to the workpiece using IJK vectors. This is rather than the traditional direct programming of the A, B, or C axis angles.  

The CNC control mimics the work typically done in the post-processor. Simulation of this motion requires the equivalent calculation to drive VERICUT’s virtual machine axes. Advanced Machine Features enable VERICUT’s IJK-to-ABC calculation function. 

Turning operations which are not symmetric about the lathe spindle, such as crankshaft turning

Special turning operations that are not symmetric about the lathe spindle are used in some machining operations. These asymmetric turning operations, like turning the connecting rod pin on an automobile engine crankshaft, can be simulated in VERICUT. This also supports non-turning material removal using a non-rotating tool, like when broaching. 

Parallel kinematics machines

Some machine tools orient the tool axis by using a linkage mechanism rather than the traditional rotary axes. This is commonly called “parallel kinematics.” VERICUT specifically simulates the Ecospeed® tripod head from DS Technologies. Other kinematics are available on request. 

Stop on contact

CGTech’s simulation software supports commanding machine components to move until they contact other components. Using this feature makes it possible to simulate a turning centre bar feed action where the workpiece feeds out until it contacts a bar stop. It also makes it possible to simulate automatic work-holding devices, such as a programmable steady rest that advances its rollers until they touch the workpiece.
