This is dependent on your NCL Version.
NCL In-Process-Verification (IPV) is NCL‘s integrated numerical control simulation and verification module.
NCL/IPV is a fast and accurate way to simulate the material-removal process of NC toolpaths.
The user can instantly verify toolpaths at any time during an NCL session.
IPV can also verify existing toolpaths from NCL or other CAM systems. NCL/IPV significantly reduces the need for costly tape prove-outs and ensures accurate, efficient, and safe NC programs
NCL/IPV is less expensive to buy and maintain than stand-alone packages. Each license of NCL/IPV comes with he ability to simulate five-axis toolpaths, define form tools and holders, and compare the cut part with a solid model. You don’t have to buy a separate module for every feature you need.
NCL/IPV is fully integrated into NCL allowing toolpaths to be simulated.
The part model can be quickly dynamically rotated, zoomed, and panned at any time during the simulation.
Errors are detected automatically, including: rapid cuts, tool holder collisions, and collisions with clamps and fixtures.
The cut part can be compared to NCL CAM surfaces or a solid model and then saved and reloaded in subsequent sessions.
The monitor panel displays the progress and status of the current simulation.
