Mastercam is a proprietary computer-aided manufacturing (CAM) software suite developed by CNC Software, Inc. It provides toolpath generation, simulation, and post-processing for computer numerical control (CNC milling, turning, routing, and wire EDM equipment. The package integrates with leading CAD systems and participates in workflows used by manufacturers, educational institutions, and defense contractors. Users rely on it for production programming, rapid prototyping, and job-shop operations across aerospace, automotive, medical, and moldmaking sectors.

History

CNC Software, Inc. founded by T. S. (Terry) Foster and Art Fenerty released the original product in 1983, coinciding with the rise of personal computers such as the IBM PC and operating environments like MS-DOS. Early adoption was driven by partnerships with machine tool builders including FANUC and HAAS Automation, and by integration with CAD providers such as Autodesk and SolidWorks. Over successive decades the product evolved alongside standards from organizations like ISO and technology trends including Windows NT, multicore processors, and 3D printing for hybrid workflows. Major milestones include the addition of 3D milling, multiaxis strategies, and simulation modules that paralleled developments at competitors such as Siemens PLM Software and PTC (company).

Features and Modules

The suite comprises modules for 2D and 3D milling, 4- and 5-axis simultaneous machining, turning, and wire EDM, comparable to offerings from Delcam and other CAM vendors. Toolpath strategies include high-speed machining, adaptive clearing, and trochoidal milling with simulation tools used alongside software from Vericut and post-processors that target controllers from Heidenhain, Siemens, and FANUC. CAD interoperability supports file exchange formats such as IGES, STEP, and native geometry from SOLIDWORKS, Autodesk Inventor, and Rhino. Ancillary modules include solid modeling, toolpath verification, probing routines compatible with metrology systems from Hexagon AB and ZEISS.

Workflow and File Formats

Typical workflows begin with CAD geometry import or native design using integrated modeling influenced by paradigms from Parametric modeling pioneers like Pro/ENGINEER (now PTC Creo). Geometry is processed into toolpaths using CAM features that reference standards such as G-code dialects and then post-processed for controllers by vendor-specific post processors rooted in community contributions and vendor support similar to ecosystems around LinuxCNC and GRBL. Supported file formats include DXF, DWG, STEP, IGES, and proprietary neutral formats used by suppliers like MSC Software. Simulation and verification stages produce collision reports and stock-model updates akin to practices in companies such as Boeing and Airbus.

Supported Machines and Integration

Integration targets cover a broad set of machine tools and controllers from manufacturers like Haas Automation, Okuma, DMG Mori, and Makino. The software supports multiaxis gantries and robots from industrial automation vendors including ABB, KUKA and FANUC Robotics for hybrid machining and automated loading cells. Post processors are tailored to controllers used in facilities run by firms such as General Electric and Siemens AG, and probing integration aligns with metrology hardware from Renishaw and Mitutoyo. Connectivity options mirror shop-floor technologies from MTConnect and OPC UA implementations in smart factory contexts promoted by Industry 4.0 initiatives.

Licensing and Versions

CNC Software distributes commercial licenses across academic, network, and node-locked models, similar to licensing approaches from Microsoft Corporation and Adobe Inc. Annual version releases and maintenance subscriptions offer updates, service packs, and technical support comparable to vendor ecosystems like Autodesk and Dassault Systèmes. Educational licensing arrangements enable adoption at institutions such as Massachusetts Institute of Technology, Georgia Institute of Technology, and vocational programs affiliated with NIMS to support curriculum in manufacturing technology.

Training, Community, and Industry Use

A global user community includes certified trainers, reseller networks, and industry groups paralleling professional bodies like SME and ASME. Training resources range from manufacturer-led certification to third-party courses offered by institutions such as CNC Training Centre partners and continuing education at universities like Ohio State University and Clemson University. Industry adoption spans sectors served by contractors like Lockheed Martin, Northrop Grumman, and General Motors for prototyping and production work. User conferences, webinars, and forums foster knowledge exchange similar to ecosystems around Stack Overflow and GitHub for technical workflows.
