Mastercam Version 8.1, which improves on the success of Version 8, features all-new verification, automatic stock recognition in Mastercam Lathe, and full associativity in Mastercam Wire. Version 8.1 incorporates a new solid-model verifier from LightWork Design LTD in all its CAM products. The new verification is the software's fastest and highest quality verification yet, bringing users added speed and flexibility in testing part programs. Users can also import any shape stock when verifying parts--including a verified model from a previous session. This new release brings a powerful new stock recognition feature to Mastercam Lathe. Each turning operation reviews any prior operation and generates a tool path only for the actual as-cut stock that is left. For example, if a user center-drills then faces a part, the software will only create a facing operation for the area left after the drill cycle is complete. With the release of Version 8.1, Mastercam Wire joins the Version 8 family. This new release features full associativity, meaning that geometry and wire path are linked. When the model or tooling information is changed, an updated wire path can be generated with a single mouse click. The new release also features a solid model verification and a fast, shaded verify that provides immediate feedback when creating wire paths. The new version offers dozens of additional new features, including network support, fast STL machining and specialized custom tool definition.
