CAD/CAM Suite Offers Smoother Surfaces



OPEN MIND Technologies AG has introduced hyperMILL 2019.2, a new version of its comprehensive CAD/CAM software suite. The latest hyperMILL software offers a range of new features including high-precision 3D finishing, 5-axis tangent machining, high-performance turning and new CAD-for-CAM technologies.

"We are pleased to offer our CAM customers with even more powerful finishing, 5-axis and turning strategies," said Alan Levine, Managing Director of OPEN MIND Technologies USA, Inc. "In addition, we have improved programming process times, and have also integrated CAD utilities directly into some CAM strategies."

When using the 3D shape Z-level finishing cycle, hyperMILL 2019.2 now offers a "high precision surface mode" option designed to provide ultra-smooth surfaces with tolerances in the micron range. This saves time on post-machining finishing processes, especially for mold makers. The "smooth overlap" function also offers improved surface finish and is available in many cycles. The transition regions for steep and shallow machining have a small overlap, including a slightly lifted cutter, resulting in enhanced finishes with imperceptible transitions.

In hyperMILL 2019.2, the hyperCAD-S "global fitting" function is directly integrated into the CAM strategy for 5-axis tangent machining. With this function, multiple faces can be joined into one face with a controlled ISO orientation. The principle of using CAD elements for CAM programming is also applied, for example, to an automatic face extension where the bounding surfaces are automatically extended during programming to improve the edges of the machined surfaces. "These dedicated CAD utilities streamline CAM programming and provide tested and proven methodologies," said a company spokesperson.

In the previous version of hyperMILL MAXX Machining, turn-roughing was implemented with trochoidal toolpaths. Now version 2019.2 offers even greater process reliability for high-performance turning by providing tool life monitoring that restricts tool use by the distance covered, the number of toolpaths or a time limit. If the defined limit is reached, a retract macro is generated automatically and the job ends.

OPEN MIND has further enhanced its feature and macro technology in the new version to enable more secure and simpler programming. Full-text searching is now available in the macro database and users can define machine and material groups as defaults to make it easier to select macros.

Hole feature linking enables CAD feature model changes to automatically transfer to hyperMILL. Since design changes in CAD are associatively linked with the CAM, users can securely make updates.

Helpful when working with very large parts, hyperCAD-S calculates the workpiece mass and center of mass with a material definition including for solid, mesh and stock models. Also, the "undercut" function makes it possible to detect undercut areas on components quickly and reliably. In addition, the new "local curvature" analysis function makes it possible to detect curvature radii on components. The minimum curvature radius, which often plays the biggest role, is output immediately, and the best possible lead angles or tool radii for machining curved faces can be determined. This can be beneficial when planning hyperMILL MAXX Machining strategies that use conical barrel cutters (also known as circle segment tools).
