The control system of the machine tool may become an obstacle to shorten the processing cycle and improve the smoothness of complex 3D models, aerospace parts, or medical device components. When the processor is unable to keep up with the speed of the program, the drive will reduce the feed rate of the tool due to the urgent need of information, thereby prolonging the machining cycle and causing the tool to operate inconsistently. In order to replace worn and overloaded tools, in addition to increasing the number of tools to the tool magazine, it also affects the effective use rate of the spindle and increases the workload and finishing time of the fitter. GBI Cincinnati and MTI Technologies collaborated on this issue and launched a series of machine tools called "Revolutionary". It is said that these machine tools combine the rapidity of modern control technology with the precision of machine movements to form a truly constant speed processing system.
Programming with a feed rate of 2540 mm/min (100 ipm) does not guarantee that the tool can reach a speed of 2540 mm/min. In fact, the speed is always lower than the target feed rate. The reason for this result lies in the ability of the control system to position the tool in the space specified for the geometry of a particular part, including the tool height offset, tool radius offset, common offset and work offset, etc. The complex algorithm, it must be able to generate every point of the path that the tool runs on the workpiece. The control system must also be able to calculate approximations and dodge movements as well as having acceleration and deceleration functions.
Most of the currently used control systems can be traced back to the roots of the development of this system, which means that it has a history of 30 to 40 years. One of the bottlenecks that existed at the time was the download speed of RS-232 connections. This type of control system has a program reading speed of up to 5,000 blocks per second. For many parts of the process, this speed is sufficient, but for complex parts, the required speed is much higher than this speed. When MTI's Carlo Miceli began developing his own control system, he adopted a completely new approach to PC language logic and effective information processing. Its product is a numerical control system based on modern PC hardware, equipped with a new tool path algorithm with a reading speed of 5000 units/s or more. GBI Cincinnati stated that the results have reached the "constant speed" processing requirements, its production speed, feed rate is also very stable.
When the speed (feedrate) is unstable, there will be some problems. When a tool is run through a part, its unbalanced movement will cause different loads on the cutting grooves on the tool, which will affect the machining accuracy and surface finish. If the speed of the tool is not fast enough to maintain the minimum cutting load of the tool, friction will occur between the tool and the workpiece rather than cutting, and the unstable movement of the tool will shorten the tool life. This mode of operation can also cause a small amount of breakage in the cutting edge, causing the tool to become hot and dull. However, with constant speed machining, the average machining speed of the tool passing through the workpiece will be more uniform and the machining accuracy will be higher. This will not only shorten the machining time but also extend the service life of the tool.
In the "Revolutionary" series of machining centers, MTI's control system does not generate excessive stresses associated with high-speed machining, allowing fluid tools to run on complex part geometries.
During the execution of the program, the result of high-speed block processing is that the random error of the control system can be monitored and adjusted stably, so that the tool can run at a uniform speed and achieve a perfect surface integrity. The system uses more than 80 high-speed buffers to monitor the operation of the tool. If the random error is exceeded, the tool motion can be adjusted immediately.
Even when machining very complex shapes, it is said that the rapidity of the control system, the fine tuning of the drive device, and the processing of the tool path can achieve a fast and accurate program execution purpose.
