Mazak CNC Machine Code Reference

Mazak Corporation is the undisputed world leader in CNC machine tools with the largest market share in the world with revenue of 5.28 billion dollars and more than a hundred years of manufacturing innovation. To the manufacturing professionals and CNC programmers, it is important to learn the complete machine code system of Mazak in order to optimize productivity and accuracy in the current machining processes.

Mazak’s revolutionary approach to CNC programming

The programming system at Mazak is a more advanced development of the old G-code systems. In 1981, the MAZATROL conversational programming system was the first conversational CNC programming interface in the world, enabling operators to program machines in normal language instead of complicated code structures. This two-mode system offers the ease of use of conversational programming and the accuracy of conventional EIA/ISO G-code, thus Mazak systems can be used by both skilled programmers and those who are new to CNC machining.

The new MAZATROL SmoothAi controllers in the company incorporate artificial intelligence that develops through the experience of programming and automatically optimizes machining processes and cutting conditions. This is a major improvement on the conventional programming techniques where AI is used to generate toolpaths, optimize processes, and predictive maintenance.

This extensive code reference shows how Mazak has developed a highly advanced method of CNC programming, with compatibility to ISO standards, but with proprietary extensions that provide high performance and productivity in contemporary manufacturing facilities.

Programming best practices and real-world applications

To program Mazak successfully, one must know conversational and G-code programming. MAZATROL conversational programming is well suited to job shop applications that require fast changeover of setups and a variety of part requirements that require a flexible programming method. Automatic calculation of intersection coordinates and toolpath optimization capabilities of the system make it a perfect choice in case the operator has to concentrate on machining rather than on the complexity of the programming.
G-code programming is necessary when geometries are complex, when toolpaths are generated by CAM, and when it is necessary to have fine control over the toolpath. The dual-mode programming feature enables the programmer to switch between conversational and G-code programming in the same program and offers the greatest flexibility to meet the varying machining needs.
Such advanced functions as the Variable Feed Control (VFC) allow optimizing feeds and speeds in real-time during the cutting process, whereas the Tool Path Store (TPS) feature makes it possible to pause the program and resume it safely. These characteristics in conjunction with the Mazak Smooth Corner Control and unlimited look-ahead processing provide excellent surface finishes and shorter cycles.

Comparison with standard implementations

The strategy of Mazak is to balance the requirements of ISO 6983 and proprietary improvements. Mazak brings a lot of value to the standard G-code functionality with conversational programming, advanced work offset management, and integrated manufacturing capabilities, all of which remain compatible with standard G-code functionality. G53.5 MAZATROL coordinate system avoids work offset conflicts because it keeps program-resident coordinates, which is a frequent cause of machining errors.

The main departure of the standard implementations is machine-specific M-codes, which are highly customized to the capabilities of Mazak hardware. The extent of Mazak integrated approach to manufacturing automation is evidenced by the robot integration codes (M20-M29), multi-spindle coordination functions and complex measurement cycles.
Compatibility with CAM software is also good, with the majority of the major systems offering Mazak-specific post-processors. Mazatrol programs are however not directly transferable to other CNC systems and long term programming strategy and operator training needs must be considered.

Essential considerations for implementation

The most important benefit to manufacturing professionals who are considering Mazak systems is the flexibility in programming that can be used to suit varying levels of skills and application needs. The conversational programming interface cuts down the time needed to train new operators, but still has full G-code capability to support complex applications.

The quickest route to productivity is through investment in official Mazak training programs, with more than 100 courses offered in the National Technology Center and online MODL platform.
The programming strategy must take advantage of the conversational and G-code capabilities instead of imposing the traditional methods on the MAZATROL system. To succeed, one should realize that the philosophy of Mazak is to describe part geometry instead of defining tool paths, so the system can optimize cutting processes automatically.

The total combination of measurement, automation, and process optimization in Mazak systems offers high competitive advantages in the contemporary manufacturing world. The advanced programming features of the system usually allow companies applying Mazak technology to attain better quality consistency, shorter setup times, and greater flexibility in production.
The fact that Mazak is the world leader in CNC machine tools and has a revolutionary approach to programming and constant technological development makes the knowledge of these machine codes a necessity to manufacturing professionals. The competitive advantage of the company in the contemporary precision manufacturing is based on the dual-mode programming system, advanced controller functions, and extensive automation possibilities.
