WHAT’S NEW

This release contains a number of important fixes and improvements, as identified below.

What's New

General

The HSMEditor has been updated to the latest version for the 2020 release. (CAM-12417)
Many icons in the user interface have been refreshed to improve constistency with Inventor. (CAM-11316)
CAM functions for 2D Profile are now enabled when the Flat Pattern environment is active in Inventor. (CAM-10631)
A warning is now issued if you edit a machine configuration that is being used in multiple setups, since the changes you make will affect all setups that reference the machine. (CAM-10281)

Post Processor

New functions 'section.getModelOrigin' and 'section.getModelPlane' were added to provide access to the work coordinate system of the CAD model. (CAM-12614)
A 'reset' parameter has been added to the createAxis function, which can reset the current rotary axis position to zero prior to scanning the section for the optimal rotary starting position. There are also corresponding 'axis.getReset' and 'axis.setReset' functions. (CAM-12300)
Post Processor: A new variable 'machineParameter.spindleSpeedDwell' has been added which specifies a dwell time in seconds when the spindle speed changes during a drilling cycle. This can be used to correct expanded gun-drilling cycles. (CAM-9495)

Fixes

General

Fixed an issue in which the stock contours preview was incorrect when another tool orientation was selected in the operation. (CAM-12649)
Fixed several issues in which toolpaths were not being invalidated when specific parameters were changed: Safe Z, Origin or Chuck Front in a turning setup, Entry and Pre-drill positions, Bottom Height 'from selected point'. (CAM-13938, CAM-13360, CAM-12632, CAM-13218, CAM-12991)
Avoid incorrect parenting of the Machine Select dialog, which could lead to a crash. (CAM-13443)

Toolpaths

When using a cutter with a corner radius in 2D Adaptive, the upper edge of a pocket could be gouged in some circumstances; this is corrected. (CAM-11596)
Allow machining two open bores within the same operation. (CAM-11647)
Fixed an issue where the software could hang when calculating helical ramps on a contour pass. (CAM-12129)
Fixed an issue in which toolpaths might not get created when using the "Fillet" option (Mac only). (CAM-12279)
Fixed an issue where faceting could occur in Scallop operations. (CAM-12326)
Fixed an issue in which helical links were detached from their cutting segment and a further lift and plunge was inserted in between to join them. (CAM-12364)
Jet will now provide the user with a better warning when no path can be computed. (CAM-12953)
Contour with Both Way and Roughing Passes used to produce partial toolpaths. This has now been fixed. (CAM-13309)
Fixed an issue in which entry positions were inadvertently removed from 2D Chamfer operations. (CAM-13676)
Fixed an issue which caused irregular cutting passes for the scallop strategy. (CAM-13757)
Fixed an issue where some arcs were misformed when offset. (CAM-13135)
Fixed an issue which could have caused gouges when smoothing for sampling strategies is enabled. (CAM-13266)
Fixed an issue in which a toolpath would not regenerated after smoothing was turned on or off. (CAM-12599)
Fixed an issue in which rapid retracts of undercutting tools could fail to report some collisions. (CAM-11401)

Turning

Fixed leads when "Use fixed lead direction" was turned off for certain inside and face grooving operations. (CAM-10679)
Use more accurate round shank holders (instead of square) for visualization and simulation of some turning tools. (CAM-11423)
Fixed issues with toolpath verification, simulation and NC code when an angled turning tool with compensation set to tip tangent was used for profiling, facing or chamfering. (CAM-11617)
Fixed an issue where the compensation point for a boring tool was incorrectly previewed in the tool library. (CAM-12236)
The non-functional 'Radial dimension mode' dropdown was removed from the turning / turn-mill setup dialog. (CAM-12448)
Fixed an issue in which the tangent compensation point for a turning tool was incorrect when changing the tool direction. (CAM-12856)

Post Processor

Fixed an issue in which "getOptimizedTCPMode" was returning an incorrect value. (CAM-11367)
A post processor error is no longer generated when a multi-axis operation has a constant tool axis of 0,0,1. (CAM-11794)
The post processor now considers a drilling operation to be an axial center drilling operation instead of a milling operation when it is within a tolerance of X=0, Y=0. (CAM-8185)
Fixed a problem in which linear values from the machine configuration dialog were not recalculated according to the output units. (CAM-11877)

INSTALLATION

New installation

Inventor must be installed prior to installing Inventor CAM
If you need to install Inventor, it should be available to you in the Autodesk Account Portal
Before you install Inventor CAM 2020, 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.
- Windows 7: Windows Update is located in the Control Panel, which is accessible from the Start 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 Inventor CAM 2020.
Before installing Inventor CAM 2020, please uninstall all prior Autodesk beta products.
Download Inventor CAM 2020 from the Autodesk Account Portal (preferred) or cam.autodesk.com.
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.

Before installing an update there is no need to uninstall a previous Inventor CAM release; but if you prefer to do so, you can uninstall the relevant release in Programs and Features in Windows Control Panel by accessing “View installed updates”.
