Helitronic Toolstudio Minimises Data Input

Helitronic Toolstudio software from Walter simplifies grinding of complex tool geometries, according to the company. The package covers every aspect of the configuration of tool geometries. Using the integrated wizard technology, tools can be modelled in a simple way. The required data input is reduced to a minimum. The system only requests the most important tool parameters and automatically runs through the necessary input screens.

At the same time, the Helitronic Toolstudio software accesses Walter's knowledge database - this stores important tool-grinding experience and helps to find a speedy solution for all production tasks. The software complements the entries with relevant geometry and technology parameters such as grinding wheel sets and grinding feed rates, for example. Based on the basic tool model created and high-precision 3D simulation, which is updated for every modification, the tool can be individually tailored.

Further functions include: 'Click and Edit' - simply click on the 3D simulation to see the relevant geometries and technology parameters; time saving - path-optimised calculation of positioning movements between operations and cutting edges; safety - automatic collision check prior to manufacture; tool design made easy - the modular design of the new version of Helitronic Toolstudio permits variable and individual configuration of all important parameters.

Using the modular principle, any number of operations can be added or copied. This extra flexibility comes in handy when processing step tools (for example, step drills or stepped milling cutters). Walter has improved the tool wizard for step tools so that it can now be restarted at any time, even after manually adding or copying individual operations. The amount of work required by the operator has been reduced, and with just a few clicks he or she can replace an existing drill cutting edge on a specialised step drill.

In the production of step tools on Walter machines, two particular probing functions of the software are helpful, the company said. One serves in the alignment of coolant holes and measures the concentricity of the blank. The other scans the flute path along the contour of the tool. It is possible to check individual diameters or steps as well as entire pro-file contours in this way. The distribution of measuring points can be freely configured.

While the tool parameters are being defined, the Helitronic Toolstudio software calculates the flute shape with specific focus on all the determining factors. The path of the helical angle, the radius of the grinding wheel bond, and the angle of the grinding wheel are just some examples. Time-consuming checking of the flute shape is not required. Accurately parallel clearance angles and land widths on the step are produced without the need for long-winded manual corrections.
