The design of modern tool grinders is very compact. Machine components and addable components increase the risk of collisions in the limited space of the machine tool. The programming system equipped with precise machine tool models can ensure the reliability of machining. The new version of NUMROTO 3.5.1 optimizes the machine model and collision test functions, and the existing NUMROTO system can be upgraded to the new version.

The NUMROTO programming system has been around for more than 20 years and is now widely used on more than 2500 tool grinders in the world. Due to the wide range of tools that can be processed by the software, the tool manufacturer can independently develop the grinding program and test the collision safety on the tool grinder.

With the continuous development of computer performance, the entire tool grinder and grinding process can be simulated with precise effects. Today, most of the machine tools using NUMROTO are equipped with 3D simulation. Due to the application of 3D-CAD technology, the structural design of modern tool grinders is more compact, and the internal space of the machine tool must be optimized to be suitable for grinding tools of various shapes and sizes.

What is more difficult is that the accessories in the machine tool can only be used to process certain tools or procedures, which hinders other processing procedures. Due to the existence of these obstacles, the programming system must constantly calculate the grinding path to prevent collisions, which requires an accurate and realistic machine tool model. NUMROTO 3.5.1 version is equipped with an easy-to-use machine tool model to ensure that the machine tool model on the computer is consistent with the real machine tool movement.

Today, this basic model of tool grinder has been used in traditional tool grinding programming systems. The machine tool is often equipped with some machine parts, such as support frame, tail seat, moving tool holder, special chuck for sintering castings or blades, dressing unit, passivation device and high-frequency spindle. Fixed-installed machine parts, such as dressing units or high-frequency spindles, are selected by clicking once from the MUNROTO machine parts list. These accessories will always be visible on the machine model until the selection is canceled. For a movable mechanical accessory like a support frame, the motion state is that the corresponding parameters have been edited. Machine parts with variable positions can remain in the stopped position during one processing step and appear in the working position in the subsequent processing steps. These are accessories that use electric, hydraulic and pneumatic drive units. Similar accessories are activated by corresponding CNC commands. The complexity in the model is that the axis controls the movement of the machine tool components, such as moving the center frame to a specified position and exiting the specified position.

Addable components can be installed on each machine part. The pressing device is installed on the movable support frame, and the guide sleeve is installed on the movable center frame. Various shapes and sizes can be selected for additional components. If the machine tool needs to reselect other tool applications, simply click the mouse in NUMROTO to select additional components of other sizes.

Machine parts and addable components are stored in the NUMROTO database, so database backups can also be performed. Since the range of options is not limited, even very complicated machine details can be displayed very realistically.

Since the machine tool model has been integrated into the programming system, before the newly generated tool program is used for machining on the tool grinder, a detailed collision safety test can be performed on the program. The collision test runs at high resolution, and even collisions between very small components can be detected.
