2024 CAM Release Updates Toolpath Capabilities

OPEN MIND TECHNOLOGIES introduced its latest hyperMILL® 2024 CAD/CAM software suite, which includes enhancements to its toolpath capabilities, and new functionality that increases NC programming efficiency in applications ranging from 2.5D machining to five-axis milling.

“As a result of our continuous research and development, the introduction of hyperMILL® 2024 offers our customers a breadth of core toolpath enhancements and new features to optimize the digital process chain and manufacturing operations,” stated Alan Levine, managing director of Open Mind Technologies USA, Inc.

An optimized deep-hole drilling CAM strategy improves machining reliability by providing a user-friendly interface with process-relevant parameters clearly defined on a new process tab. New capabilities allow coolant and dwell time stages to be identified, a chip break to be integrated into a drilling process, and more. A new, single-tip gun-drill tool simulation function provides precise collision checking and a detailed visualization of the stock removal.

A new algorithm for three-axis and five-axis Rest Machining automates detection of all rest material areas, and optimizes toolpath calculations for faster, reliable machining. Toolpaths are now optimally divided to ensure more efficient machining, and the detection of intersection areas where paths meet has been optimized for collision avoidance.

An additional toolpath improvement is an enhanced path layout for the 3D Plane Machining cycle. The new strategy has a smoother path and fewer pick-ups. While the toolpath length (distance) may be longer in some cases, tests on a variety of NC controllers demonstrate that the machining time has been reduced.

A novel generation of programming assistance and analysis, “CAM Plan” is introduced in hyperMILL® 2024, simplifying various programming tasks and identifying possible sources of error. Predefined workflow steps safely guide users through the preparation and programming process, while the geometries and features required are automatically created. Also, potential errors are flagged for removal such as double surfaces or gaps between model patches.

Once the data is organized, the CAM workflow can be processed with more intelligence and higher efficiency. The first benefit from hyperMILL® CAM Plan is that component topology is analyzed to produce a precise toolpath that has command locations aligned with key geometric features and with optimized point distribution for milling. The result is improved surface finishes, easier processing by NC controllers, and reduced machining times.

For easy generation of three-axis and five-axis NC programs with axis change and an optimized use of the workspace, the NC Optimizer feature in the hyperMILL® Virtual Machining strategy now offers the option to transform X- and Y-axis movements into a single movement with the rotation axis in the table. By swapping axes, an XY movement is transformed into a simultaneous CX movement which eliminates rewind movements during machining.  This is especially impactful on machines that have a limited linear axis range.

The reading back of measuring points when using hyperMILL® Virtual Machining is a new feature that allows graphical representation of measured points on the part model, rather than comparing a list of measurement results. Users can also quickly identify measuring points that are out of tolerance on a 3D part model and compare trends over sequential measurements. As a result, it is much easier to analyze and compensate for inaccuracies and tool wear after milling.
