France/USA – DP Technology has announced the release of Esprit 2017, the latest version of its pioneering flagship product. This version delivers a smarter, simpler, faster machining process with expert toolpath, streamlined user control and accelerated processing power, the company says.
According to DP Technology, the new version features a new 3-axis Global Finishing cycle that allows for the steep/shallow milling of complex part geometries by applying an appropriate toolpath to complex parts based on model analysis and a single threshold angle. Z-level cutting passes are applied to steep areas and boundary offset passes to shallow areas that gives priority to toolpath continuity between steep and shallow areas for smoother finishing. A time-saving option constructs toolpath to machine over openings and holes in the CAD model without stopping or retracting the tool.
A redesign of the Esprit facing also reduces several steps needed to face a part. Up-to-the-minute intelligence about the shape of in-process stock is now built into facing, pocketing and contour milling for faster, more reliable programming. The stock automation engine inside this version underwent a refactoring to reduce calculation times from minutes to seconds for facing, pocketing and contouring. The same refactoring was applied to Esprit’s 3-axis roughing to compute in-process stock in much less time, even on complex parts.
Awkward profiles in wire EDM parts are now cut more efficiently with its open profiles in EDM pocketing. When a profile is interspersed with small or oddly shaped openings, the wire can be programmed to ignore those openings for a simple slug drop, followed by precise no-core pocketing that burns away only the small pockets of material that remain.
Advancements in Profit-Milling improve performance inside closed cavities for better chip evacuation and coolant access and faster programmed feed rate. Lathe contouring has now more options for accurately positioning the tool edge along walls, at the start or end of cutting passes, and between walls. Lathe programming enhancements are particularly advantageous when contouring with round or grooving inserts.
Several enhancements to 5-axis swarf milling has improved its responsiveness to a wider range of unusual part shapes for smoother, more reliable machining. Automatic machining over gaps in surfaces, reliable pass extensions along ribs, and smoother positioning of the tool along walls with irregular borders eliminate the time-consuming process of creating extra geometry on complex 5-axis parts, the company explained.
