Modern tool grinders are very compact in design. Machine parts and add-on components increase the risk of collisions within the limited space of the machine. A programming system with a precise machine model ensures the reliability of processing. The new version 3.5.1 of NUMROTO optimizes the machine model and collision test functions. Existing NUMROTO systems can be upgraded to the new version.
The NUMROTO programming system has been on the market for more than 20 years and is now widely used on more than 2,500 tool grinders in the world. It is chosen by tool manufacturers because of the wide range of tools that the software can process, the ability to independently develop grinding programs on tool grinders and test collision safety.
With the continuous development of computer performance, the entire tool grinder and the grinding process can be simulated with precise effects. Today, most machine tools using NUMROTO are equipped with three-dimensional simulation. Due to the application of 3D-CAD technology, the structure design of modern tool grinders is more compact, and the internal space of the machine must be optimized to be suitable for grinding tools of various external dimensions.
What is more difficult is that the accessories in the machine tool can usually only be used to process certain tools or programs, which hinders other processing programs. Due to the presence of these obstacles, the programming system must constantly calculate the grinding path to prevent collisions, which requires an accurate and realistic machine model. NUMROTO version 3.5.1 is equipped with a user-friendly machine model, which ensures that the machine model on the computer corresponds to the real machine movement.
Today, this basic model of a tool grinding machine is used in traditional tool grinding programming systems. The machine tool is usually equipped with a number of machine tool components, such as a support, tailstock, mobile steady rest, special chucks for sintered castings or inserts, dressing units, passivation devices and high-frequency spindles. Fixed machine tool components, such as dressing units or high-frequency spindles, are selected from the MUNROTO machine tool component list by clicking once and remain visible on the machine tool model until the selection is cancelled. For movable mechanical accessories such as the support, the movement status is already programmed with the corresponding parameters. Variable-position machine tool components can remain in the rest position during one processing step and appear in the working position in the subsequent processing step. These are accessories using electric, hydraulic and pneumatic drive units. Such accessories are activated by corresponding CNC commands. The complex part of the model is the movement of the axes that control the machine components, such as the movement of the mobile steady rest into and out of position.
Additive components can be mounted on each machine component. The clamping device is mounted on the mobile support frame, the guide bushing is mounted on the mobile steady rest, and the additive components are available in a variety of shapes and sizes. If the machine needs to be re-selected for other tool applications, additional components of different sizes can be selected in NUMROTO with a simple click of the mouse.
Machine components and additive components are stored in the NUMROTO database, so database backups can also be made. Since the range of optional additions is unlimited, even very complex machine details can be displayed very realistically.
Because the machine model is integrated into the programming system, the newly generated tool program can be tested for detailed collision safety before it is used in the tool grinder. The collision test is run at high resolution and even collisions between very small components can be detected.
