Machine Tool protection and condition monitoring Protect your machine and tooling w w w. d i g i t a l w a y g r o u p. c o m Minimize damage resulting from collisions Monitor and analyze your machine behavior
Machine Tool protection and condition monitoring w w w. d i g i t a l w a y g r o u p. c o m is a 3-axis accelerometer sensor and processor specially designed and built in Digital Way s lab to provide you with the most effective means for protecting your machines against damage resulting from a crash or a collision. Mounted on your machine s spindle, this powerful system also allows you to record vibration data associated with the conditions of machine use or with tooling quality. Why monitor vibrations? Vibration monitoring is a key strategy to ensure the quality of your production, to check your tooling, and your machine components. This is also the fastest way to detect a collision and stop your machine quickly enough to prevent damage and downtime. Consequences of a crash during a machining operation are generally catastrophic: - Broken Part or Tool-holder, - Damaged spindle, - Need to re-do all mechanical set-up, - Long downtime and production stoppages. system What for? To minimize consequences of a crash and to reduce the repair costs. Reduce cost How? Once installed on the machine, quickly detects a crash and immediately stops axis motion. On many applications Why? Small, easy to install and adjust, can protect machine tools, industrial robots, gantry systems, and industrial equipment. Machine Tool Velocity Minimizing crash damage The graph to the right shows the benefits of using the system when a crash occurs on a machine. When a machine stop is decided by an overcurrent alarm on an axis movement, it s often too late to avoid large damages to the spindle / tool / part fixture, leading to long downtimes and increasing your manufacturing costs. Of course, the will not prevent the crash, but its extremely fast reaction time will allow a much faster machine stop and thus a drastic reduction in the repair costs. Alarm Machine-Tool Axis Over-current Alarm Time to Machine Tool stop Money The Advantage Minimize crash damage by reacting fast to an impact and excessive vibration that involves spindles and/or part fixtures.
Machine Tool protection and condition monitoring w w w. d i g i t a l w a y g r o u p. c o m is available in several models, depending upon your needs and machine specifications. It can be used in «stand-alone» versions or as an addition to the Wattpilote to create the most complete monitoring solution for your machines and your tools. Most important: an industrial sensor Encapsulated in an M12 housing, the 3- axis acceleration sensor was designed to be a real industrial product. It is durable, compact, easy to install, and it has a quick-disconnect cable. In order not to be disturbed by the environment, the sensor output is digital: no need to take special precautions, the sensor cable can be mixed in the cable carrier system with the power supply cables for the spindle. For each type of machine, one solution The system may be used on any type of machine tool. It may also be used on many robotic applications (palletizer, drilling, deburring, or welding robots) and material handling machines such as gantries. Access Machine tool, Robot, Gantry Extand Transfer line, Robot Adaptable to all types of machining can be successfully applied on most kinds of machines: Machining centers, turning centers, grinding machines. It can be used only for machine protection, but it can also provide useful information about machine and tooling health. Premium Machining centers, turning centers, grinding machines Convenient installation in the electrical cabinet The signal processing box is mounted in the machine tool electrical cabinet. It connects to the PLC or machine control via a small number of discrete I/O. The 3-axis digital accelerometer is mounted on the spindle or part fixture. A quick-disconnect cable is between the processor and the accelerometer. MicroMon One touch set-up system The optional MicroMon graphical HMI display allows fast and easy process limit changes when production lot sizes are small: It's just necessary to activate one touch before the first part is machined and Micromon automatically analyzes vibration and adjusts parameters.
Successfully applied on most kinds of machines Easy to use No need to be a vibration expert to handle this system. Its simple interface has been specially developed to make it accessible to anybody, even without any knowledge about vibration sensing. Easy to install and set-up achieved with only a few clicks. Limit damage The vibrations in the X, Y, and Z directions and the RMS vibration are shown along the top of the screen. The Shock plot shows fastresponse impacts and the Vibration plot (actually RMS vibration) shows the time-averaged vibration level. With a reaction time of around 0.5 milliseconds, the will effectively reduce the damage resulting from unexpected events during your machining process. Ensure quality Excessive vibrations during machining are one of the main sources for degrading the quality of your production. This system will help you keep your machine working in good condition. Its very high sensitivity will also give you the ability to detect out-of-balance problems with your high speed tooling. Events record This system will act as a true black box that will allow you to track all unexpected events occurring during the use of the machine. Each alarm will be stored in the system s memory with the corresponding shock and vibration curve. Check Spindle health Keep an eye on the spindle condition by checking vibration levels in 3 different axes. Its very high sensitivity will also give you the ability to detect out-ofbalance problems with your high speed tooling.
