Build 19.0.0.44297 / 10 April 2024 Autodesk, Inc.

This document covers the following HSMWorks products:

WHAT’S NEW

Changes for Adaptive

Use a box test to find which pocket in the next Z-level to machine in 2D Adaptive. Expect a slightly faster speed when using a large number of pockets with 2D Adaptive and "order by depth" disabled. (#49092)
Improved the calculation time of Adaptive machining on large parts. (#48039, #47802)
Fixed an issue that could occur when exit positions were used in 2D Adaptive with conventional milling. (#48426)
Fixed an issue that could cause a crash when exit positions were used in 2D Adaptive with zero linking clearance. (#48425)
Fixed several issues that could result in a gouge when using Adaptive Clearing. (#46475, #48834)
Fixed an issue for 3D Adaptive that could lead to a stock collision in a plunge move in some cases. (#44735)
[are Whisper cuts in Fusion only (mention of FF)??] Fixed an issue where the combination of the Feature Flag to reduce whisper cuts in rest machining could cause minimal retracts to collide with the model. (#47537)
[are Whisper cuts in Fusion only (mention of FF)??] Fixes an issue where reduced whisper cuts in rest machining and reduced air cutting caused a crash in the execution. (#45454)
[are Whisper cuts in Fusion only (mention of FF)??] Whisper cuts have been reduced in Adaptive Rest machining in the case when there is a non zero minimum cutting radius. (#43110)

Changes for Contour and Pocket

Improved linking performance for Pocket Clearing. (#44926)
Fixed a failure that could occur when using exit positions for 2D Contour when Right compensation is used. (#48107)
Fixed a failure that could occur when using exit positions for 2D Pocket when Conventional milling is used. (#48107)
Fixed an issue in linking for Contour which could cause missing lead-out arcs. (#46202)
Fixed an issue in which transitions in Pocket Clearing could cause tool over engagement. (#50089)
Fixed undesired behaviour in Pocket that could occur when no stock or machining boundary was selected in rest machining. It now uses a shilhouette boundary of the rest surfaces, setup stock or selected bodies. (#47057)
Fixed several issues that could cause crashes in 2D Contour, 2D Pocket and ContourClearing in some cases. (#47123, #49843, #49748, #38399)

Changes for Blend, Flow, and Multi-Axis

Blend with Stepover Calculation set to On Surface can now auto-generate drive-curves if only surfaces are selected. (#48010)
[Possibly Fusion only???] Added an option to reverse steps direction in Blend. (#49418)
Fixed a possible gouge in Blend, Flow and Multi-axis contour with enabled 5-axis and taper tools. (#48249)
Fixed an incorrect validation error that could occur in Blend, Flow and Multi-axis contour ("(contactOffset >= 0.0) and (contactOffset <= cutterRadius - cornerRadius)". (#21080)
Fixed an issue in which Flow, Blend and Multi-axis contour were not working with slot tools. Now they produce a warning and generate a toolpath which doesn't allow machining undercut areas. (#48093)
Fixed a performance issue that could occur in some cases when calculating the "Blend" operation. (#36472)
Fixed an issue that could cause a crash in Blend, Flow and Multi-axis contour in some cases. (#36477)

Changes for Other Milling Strategies

Fixed an issue in which Engrave could miss cutting passes if "Maximum Stay-Down distance" was small. (#48395)
Fixed cutting path ordering to work 'top-down' for Engrave with the 'Multiple depths' option enabled. (#46503)
Fixed a possible gouge that could occur in some cases in Flow and Multi-axis Contour. (#42005)
Improved performance and fixed potential hangs in 2D Profile. (#9087)
Fixed an issue in which the "Repeat pass" option was not working in Trace with enabled left/right compensation. (#48631)
Fixed an issue in which incorrect trimming could occur in Parallel when using "avoid" surfaces. (#41960)
[Needs User description???] AttributeError: 'OverriddenPencil' object has no attribute 'fssurf' (Pencil & Scallop)(#47757)

Changes for Stock Simulation

Fixed an issue in which stock simulation could cause the software to crash. (#49064)
Fixed an issue in which stock simulation of individual strategies could fail in some circumstances. (#30350)

Autodesk HSMWorks 2025 supports Microsoft Windows 10 64-bit and Windows 11 64-bit.
HSMWorks 2025 is compatible with the 2022, 2023, and 2024 versions of SOLIDWORKS.

New installation

SOLIDWORKS must be installed prior to installing HSMWorks
Before you install HSMWorks 2025, please make sure to run Windows Update, install all Windows Updates that are pending on your machine, and reboot:
- For Windows 10: Windows Update is available in the Update and Security section of Windows Settings, which is available from the Windows menu.
It is sometimes necessary to perform a Windows Update multiple times to completely update your operating system.
Verify that enough disk space is available on your machine to install HSMWorks 2025 (approx. 2 GB).
Before installing HSMWorks 2025, please uninstall all prior Autodesk beta products.
Download HSMWorks 2025 from the Autodesk Account Portal or from your Autodesk Desktop Application.
Follow the instructions to download and launch the installer. Temporary extraction is to your temp folder. Operating system errors regarding very long path names can occur if the temporary location is nested too many levels deep.
If the installer does not launch, browse to the folder where the files were extracted, and double-click setup.exe.

Updating an existing installation

When a new update is available, an update notification will appear in the Autodesk Desktop App.
Please download and install the update package.
We recommend that you uninstall HSMWorks 2024 before installing HSMWorks 2025. You can uninstall the relevant release using the Autodesk Uninstall Tool or using "Add or remove programs" in Windows Settings. If you choose not to do that, you may need to be aware that:
- HSMWorks 2025 will now be registered with SolidWorks instead of HSMWorks 2024.
- If you uninstall HSMWorks 2024 at a later time, you may lose the registration of HSMWorks 2025 with SolidWorks. The registration between the two products can be restored using the following command, which requires admin privileges to run: regsvr32 "C:\Program Files\Autodesk\HSMWorks 2025\hsmsw.dll"
Before installing any updates after the annual release (e.g. HSMWorks 2025.x) there is no need to uninstall the previous HSMWorks release.
