Create A New Tool Library

Save all tooling details in the MillMage Tool Library to make setting up machining operations easier, faster, and more repeatable. MillMage Tool Libraries are a human-readable text file stored in a folder of your choice, locally on your computer or remotely through a network share.

Tool Library window

Create Your First Tool Library

  1. Open the Manage Tool Library window by selecting CNC ToolsTool Library in the main menu.

    The CNC Tools tab in the main menu is open with Tool Library highlighted

  2. Create a new MillMage Tool Library by selecting New Library.

  3. Choose a memorable folder on your computer or network share to store the new tool library file. Name the file as desired and select Save to save the new tool library file.

    The location of the active tool library will now be displayed at the top of the Manage Tool Library window.

  4. Create a new tooling category by selecting the Create new category button, and update the category name, such as "End Mills" in this example. Press Enter or click within the window to save the category name.

    Tip

    How you choose to organize your tools is up to you — you can organize by Tool Geometry, material type, or even machine, if you've got multiple CNC machines in your shop.

  5. Create a new tool in the selected category by pressing the Create new tool in selected category button.

  6. Select the tooling geometry from the dropdown list. Your selection affects the types of Operations you will be able to select to use with a given tool, and the appearance of the simulation in the Preview window.

    Info

    Tooling Geometry

    • End Mills have sharp edges that cut material as the tool rotates and moves laterally (along the X and Y axes).

      The bottom of a standard End Mill is flat with sharp corners, resulting in flat clearings, and sharp corners at the edges of cleared areas.

      Some End Mills have rounded corners meeting at a flat surface, and produce flat clearings, but sloped corners at the edges of cleared areas. You can enter the radius of the rounded corner in the Corner Radius field of the Tool Properties section.

    • Ball Mills have completely rounded tips, resulting in rounded grooves with sloped edges where the tool has carved. Ball Mills are typically not used for clearing large areas.

    • V-Bits have angled tips that can create Chamfered edges, or angled grooves in material.

    • Drill bits have sharp tips to make vertical cuts (along the Z axis) into material.

    • Round-over bits have an inverted radius meeting at a tip, used to created rounded edges rather than sharp corners.

  7. Populate the rest of the Tool Properties section with the dimensions and details available from your tooling manufacturer. Available fields will change based on the tool geometry. Select Apply Changes to save the tooling details.

    Tooling Details

    Label Value
    Name User defined tool name
    Vendor Brand name or other sourcing information
    Tool Number Used on CNC machines with tool changers only
    Diameter Measurement of the cutting surface across the center of the rotating cutting edges — also known as the cutting diameter — with smaller diameter cutters creating tighter inside corners
    Flute Length Measurement of the cutting edges along the shaft of the tooling — also known as the cut length
    # of Flutes The number of channels cut into the tooling shaft that evacuate material chips from the workpiece
    Corner Radius Measurement of the tiny curve at the edge of the cutting surface to allow for cleaner floor corners. Set to 0 for a square end mill with no corner radius
    Included Angle For V-bits only, the angle of the cutting edge as measured from the tooling shank centerline
    Tip Length For Drill and Round-over bits only, the length of the cutting tip at the bottom of the tool
    Display Units The units of distance and speed that will display alongside the tool. Select Automatic to use your default MillMage settings, or Metric to display metric units

    Feeds and Speeds

    The Feeds and Speeds saved to a given tool in your Tool Library are automatically entered in the Operation Settings Editor when you select that tool. You may make manual adjustments to these settings after a tool has been applied to an operation.

    Label Value
    Feed Rate How quickly the tool moves through the material laterally along the X and Y axes during operations
    Finish Feed (% of Feed Rate) The reduced speed percentage used to provide a finer cut surface when the tool is making the last cutting path through a material
    Plunge Rate The feed rate at which a tool is driven straight downwards — or plunged — into the workpiece in only the Z axis
    Ramp Feed The feed rate at which a tool is driven down into and across workpiece — used in moves down along the Z axis and over along the X and Y axes
    Spindle Speed (RPM) The rotational speed of the tooling — Not all CNCs allow Spindle Speed control through software — some have routers which must be adjusted manually
    Depth Per Pass The depth of material to be cleared with each pass of your router, with the total number of passes equal to Final Depth / Depths Per Pass
    Step Over The distance between each path of your chosen clearing pattern — a larger Step Over leads to greater distance between each path
    Step Over (%) The ratio of Tooling Diameter to Stepover value
    What Feeds and Speeds should I use?

    The proper Feed and Speed settings depend on your tool, machine, material, and use case. In short: there's no easy answer that question.

    For specific recommendations, the best resource is usually the manufacturer of your machine or tool.

  8. Continue adding your available tooling to the Tool Library. Select OK when finished to save the updated tooling list and to close the Manage Tool Library window.
