oday we have released HSMWorks 2012 R4. Some of the new features and changes are listed below. You can see the complete list of changes under history when choosing download. Documentation * The manual has been reorganized and has been significantly updated. User Interface * The cycle type is now presented directly in the operation manager for drilling operations. * The type of pattern folders is now presented in the operation manager. * Added support for previewing of patterns directly from the operation manager. * Added support for adding pictures for the individual operations for setup sheets. * Added support live stock preview for combined mill/turn from the operation manager. * Improved geometry height analysis performance. * Added support for selecting faces and other geometry in assembly mode for associative heights. * When selecting faces/edges/points as heights the radii are now used for 4-axis milling and turning mode. * Added support for new units for value expressions. The following units are now supported cm, ft (feet), mil (1/1000th inch), thou (1/1000th inch), yd (yard). * Updated tool library for turning setup. * Improved rest stock preview generation performance for turning. Turning * Added support for confinement for turning using geometry selection. * Added tool preview when editing turning operations. * The initial job stock is now also previewed when editing the first turning operation in the job. * Added support for sliced stock preview for turning job. * Added support for irregular stock for turning rest machining and turning stock preview. * Added support for rest machining from initial job stock for turning profiling and grooving. Milling * Facing is now supported for 2D pocket when using only stock contours without model. * Added option to force leads to center of holes for bore and thread milling. * Added support for finishing pass for bore milling. * Added support for continuing rest machining from previous job. * Added separate Ramp Spindle speed setting for optimal cutter ramping. * Added support for separate tangential start and end extension for 2D contour. * Added support for finishing feed for facing. * Added support for forcing ramping in stock for horizontal clearing. The default is still to plunge outside stock when possible. * Improved generation performance for flow. * Generally improved linking for smoothness and reduced machining for all machining strategies. Multi-axis milling * Added support for shortest path linking for swarf and multi-axis contour. * Added support for shaft and holder for flow and multi-axis contour. * Added support for negative tangential extension for swarf and multi-axis contour. * Added repeat pass support for all modes for swarf. * Added support for both ways linking for multi-axis contour. * Added support for tangential fragment extension for swarf. * Added support for minimum tilt for multi-axis contour and flow. * Improved toolpath quality for 4-axis swarf and multi-axis contour. * Improved lead in/out control for swarf. * Improved retracts for multi-axis contour.
