What is the .MTL File Extension?

.MTL File Extension Description:

MathLook is an add-on utility for the Microsoft Excel program. Microsoft Excel is a spreadsheet program that allows users to store data in tables and cells. The program also allows users to use calculations and formulas to process the data input in the cell. However, Excel requires a strict syntax when creating equations for the data in the cells.

MathLook is a plug-in, which adds functionality to the Microsoft Excel program. Plug-ins or add-ons are used with an existing program. Plug-ins does not work on their own; they draw from resources and processes that already exist in the main program.

Files with the MTL file extension are used to store formulas needed and created by MathLook. Users can use MathLook to create formulas in plain mathematical equations and Microsoft Excel will still recognize them. Files with the .mtl file extension contain equations and formulas, which can be used repeatedly.

The MTL file extension is used to store tool libraries for Mastercam. Mastercam is a series of programs that are used to create and make computer aided designs and manufactured drawings. The program uses tools, which mimic the actions of real life tools and equipment. Tools included in the program line are used for contour, pocketing, drill, face, peel mill, surface high speed, engraving, and advanced multiaxis. The software comes with the mill tool library saved with the file extension .mtl.

The program references Mill tool libraries with the MTL file extension when users access the tools. Files with the .mtl file extension store the processes used by the mill tools available in the program. Processes in the .mtl file extension are used to create paths, which closely resemble the marks left by a real tool.

Mastercam can be used to design actual products and objects. Its use of simulations of real tools allows users to test what kind of tool to use to mimic the finished design. Users can also design their own tools that are used to create designs. Mastercam also allows additional tools from third-party programmers to be added to the program.
