Understanding Mill-Turn Licenses
Mastercam Mill-Turn is a set of tools and features which runs on top of Lathe. It uses licenses differently than other Mastercam products. Mill-Turn requires both a license for the product, and a license for each individual .machine file. This is different than Mastercam Mill and Lathe, which only require a product license.
A typical Mill-Turn installation therefore requires the following licenses:
- Mastercam Mill-Turn
- Mastercam Lathe
- One or more Mastercam Mill licenses for the desired level of Mill functionality: Mill, Mill 3D, Multiaxis
- A license for each individual .machine file
These requirements describe the most common applications, such as a multi-stream machine with B-axis capabilities or dual turrets. There are exceptions for simpler applications, however.
While in general each Mill-Turn .machine file requires its own individual license, generic machines are available for evaluation or training purposes. These do not require a separate license. Generic .machine files are available for a number of standard machine configurations for both Seimens and Fanuc controls:
- Single-stream two-spindle (Fanuc, Seimens)
- Single-stream single-spindle (Fanuc, Seimens)
- Single-stream single-spindle + tailstock (Fanuc, Seimens)
- Multi-stream twin-turret (Fanuc)
- Multi-stream turret + B-axis head (Fanuc)
- Single-spindle + tailstock (Fanuc)
However, users of these machines still must have the proper product licenses.
Mill-Turn .machine files for single-stream machines with no more than one rotary axis do not require a Mill-Turn product license. These can be run by any Lathe user; the only product license required is Lathe.
When a Lathe user loads one of these machines, they get access to the entire Mill-Turn product (subject to the capabilities of the specific machine) without needing to purchase a Mill-Turn license. This includes the same Machine Simulation features as the full Mill-Turn product, the ability to use component libraries and tool locators, the Job Setup module, access to the Sync Manager for machine-specific options, and the other Mill-Turn functions.
Lathe users can also load and run the generic single-stream machines without purchasing an additional .machine file license:
- Single-stream two-spindle (Fanuc, Seimens)
- Single-stream single-spindle (Fanuc, Seimens)
- Single-stream single-spindle + tailstock (Fanuc, Seimens)
A Mill license is also typically required to create milling operations.
Unlike other Mastercam products, Mill-Turn users who want to develop or edit posts need a Developer license. This allows access to the MP.NET development environment and other resources. Please contact Mastercam to learn more.
