Machining marks are often visible at transitions between steep and flat areas, or at the extents of rest machining regions. The ‘soft overlap’ function in hyperMILL is designed to greatly reduce this effect, whereby the milling tool is briefly lifted to blend the milling paths into one another. This functionality prevents visible transitions from being created.
When 3D roughing with high feed cutters, the step-over distance can be calculated from the scallop height measured against the tool’s geometry. Here, a special toolpath movement removes rest material from corners when there is a very high lateral infeed. Open Mind says that intelligent cut division and optimised toolpaths provide greater process safety for any remaining thin ridges.
The CAD module in version 2018.1 of hyperMILL now boasts a time saving solution known as ‘global fitting’, which creates a single cohesive face from a set of multiple faces. Many CAM strategies can then follow the ISO U-V orientation of the surface patch, increasing their application accordingly.
The hyperMILL Virtual Machining simulation solution creates a perfect virtual rendering of reality in the machine based on NC data. Built with Industry 4.0 in mind, there is a bidirectional communication link between the machine control and the hyperMILL Virtual Machining Center, thus delivering a new level of process control and optimisation.
