Improved Machine Configuration Workflow

Mastercam 2020 gives you more power for setting up machining jobs and configuring .machine files for Mill-Turn. A suite of new tools works together to significantly improve and streamline the Mill-Turn workflow.

New Machine Configuration Page

The Job Setup workflow has been enhanced with the addition of the new Machine Configuration page. Use this page to select the chucks and jaws to be loaded on the machine.

The Machine Group Properties dialog box, showing the new Machine Configuration page.

  • Previous versions of Mastercam required you define chuck jaws for each part. In Mastercam 2020, you can save chuck jaws to a component library and re-use them in multiple parts. You can define as many sets of chuck jaws as necessary.
  • You can also define different chucks and save them to a component library so they can be managed together with jaws. In previous versions of Mastercam, you were limited to the chuck that was built into the .machine file and only machine developers could make changes to the chuck. Mastercam 2020 allows you to swap out chucks for each part by selecting them from their library.
  • You can select which chucks and jaws to use as defaults.
  • The Machine Configuration page also lets you enter minimum and maximum spindle speeds directly as part of the Job Setup. Previously, these values were saved in the machine definition and needed to be edited there. Moving these settings to the Job Setup tab makes it more convenient for you to enter values.

New Tool Locator and Component Library Functionality

The workflow for managing tool locators and component libraries has been reworked and is now available to all Mill-Turn users. Now any Mill-Turn user can create or edit tool locators and manage their tool locator libraries, instead of being dependent on your Reseller or machine developer. You can open the component library by right-clicking on the .mcam-gmd file in the Machine Explorer in Code Expert and selecting Open or by double-clicking it.

The right-click menu of the Machine Explorer in Code Expert.

Mastercam opens the library and displays it in the new Mill-Turn Component Library dialog box:

You can use the new interface to easily to do any of the following:

  • Import tool locators from other libraries.
  • Create new or custom libraries.
  • Create new tool stations—including half-index tool stations—or edit existing ones.
  • Edit or shift the tool mounting locations on the block.
  • Edit or replace the solid model used to simulate the locator.
  • Create completely new tool locators as required.

Many tool locator libraries are already available on Mastercam’s Tech Exchange ( and are available to any Mill-Turn users. The component libraries themselves have been enhanced so that users can store chucks and chuck jaws in them. In addition, you can select the chuck and jaws that will be used as the default for each spindle.

This means you can easily store turret tool locators, spindle tool locators, chucks, and chuck jaws in the same component library. The new Machine Configuration page (New Machine Configuration Page) exposes these components to you during Job Setup, allowing for flexibility in configuring the machines for each job.
