Release Notes

v1.12

Release date: 5 February 2024

Features

• Chamfer tip offset

  • CAM Assist will now offset the tip of the chamfer tool, when machining modelled chamfers, without gouging the part.

  • This method avoids engaging the tip of the chamfer tool, where the cutting speed is zero.

  • In addition, it allows for slower spindle speeds or higher feed rates to be used in chamfering, which should prolong chamfer tool life.

  • This update does not affect deburring.

• Avoidance geometry (see the General tab)

  • Avoidance Geometry blocks out portions of the stock that you don't want to be machined in the setup. These blocked-out portions (referred to as ‘Avoidance Geometry’) are different from Fixture bodies. While Fixture bodies MUST be avoided, the Avoidance Geometry is considered part of the stock and MAY be gouged in specific cases. For example, drilling a through hole may pierce the avoidance geometry but not the Fixture.

  • Fixture bodies also require clearance from any tool, whereas all roughing tools may touch the surface of the avoidance geometry.

  • Avoidance Geometry has a very specific application for 3+2 setups, where controlling the tool placement around work-holding is required.

• Shaft clearance for floor finishing

  • When the shoulder length of a tool is within 1mm of the pocket depth, CAM Assist would produce a floor finishing toolpath that fails to generate in Fusion, due to the default value of 1mm for shaft clearance.

  • For floor finishing toolpaths, this clearance value has been reduced by CAM Assist to allow machining pockets with a depth less than 1mm from the full usable length (LU) of the tool (also called shoulder length in the Fusion tool library).

• Independent selection of 3+2 roughing and finishing directions (see the General tab)

  • The previous version of CAM Assist introduced the ability to choose different machining orientations for roughing and finishing. However there were limitations that led to problems if you chose completely different directions as opposed to one being a subset of the other. These limitations have been removed and roughing results are improved when the roughing orientations are completely different from finishing.

• Reduction in gouges for 2D Contour operations

  • Since lead-ins and lead-outs for 2D Contour toolpaths are not checked for collisions in Fusion, they would often cause large gouges to the model. CAM Assist will now simulate the entries and reduce the arc size below the Fusion default values in order to fit collision free entries into tighter spaces.

• Support of Fusion Machine Library (see the General and Tool use tabs)

  • CAM Assist will now read Local machines (defined in Fusion’s Machine Library) in the ‘Choose machine’ field. This means it is easier to provide your specific machine details to CAM Assist. The Generic machine list has also been streamlined for simplified access.

• Spot Drilling toolpath type (see the Advanced tab)

  • Users can now include Spot Drilling operations to spot/center holes that will be later drilled by CAM Assist. For these operations, CAM Assist will use a Spot Drill tool from the selected library to pierce holes before drilling them, namely by plunging to a fixed depth of 0.020”/ 0.5 mm.

• Frictionless software updates

  • When a new version of CAM Assist is available, users can now upgrade the add-in in an easy way by clicking an ‘Update’ button, which will initiate the installation process.

Improvements

• 3+2 performance

  • By reducing the number of machining directions considered for ball nose tools, the time taken to run CAM Assist on complex 3+2 parts has been significantly reduced.

• Tool selection for fillets and profiles

  • CAM Assist is now more likely to choose the same tool and toolpath for finishing continuous fillets, reducing excessive linking movements and improving surface finish.

  • This is especially evident in 3+2 machining when some surfaces of the fillet could be treated as a wall from alternate cutting directions.

  • CAM Assist is more likely to choose a single tool for wall finishing profiles, especially in cases where the previous strategy was split by a sharp corner.

v1.11.0

Release date: 20 December 2023

Features

• Multiple Tool Orientations Selection with 3+2 Machining (see the General tab)

  • Following on from your feedback, we have evolved our 3+2 feature to give you more options for selecting the machining direction:

    • Aligned to the X, Y and Z axes

    • Select ‘by setup’

    • Full automatic selection by CAM Assist (beta customers only)

  • If you select the direction ‘by setup’, you can then also:

    • Decide if you want to use the same direction for roughing and finishing

    • Use the interface to select which directions you want to machine the part from (respecting the order of selection)

Please be advised that CAM Assist’s ‘SteepAndShallow’ option is in Beta with ‘Contour3D’ currently the default. In some instances SteepAndShallow may yield better toolpaths and/or machining time results. This can be selected in the 'Finishing' section of the 'Advanced' tab. Also, you can’t edit roughing or finishing modes in the ‘Advanced’ tab if you don’t have these modes selected.

• New User Interface (see CAM Assist’s Layout)

  • We have slimmed down the menus on CAM Assist to deliver the most used features on the General tab. So as well as your tool library and material, you’ll now find your workholding security per setup, as well as our new 3+2 orientation selection options. 

  • All the other tabs have been combined into the ‘Advanced’ tab, with ‘Tool Use’ unchanged.

• Hole Patching is enabled by default (see the Advanced tab)

  • You can toggle this setting in the ‘Roughing’ section of the ‘Advanced’ tab. Hole patching will prevent roughing passes from machining material away that would otherwise be handled by hole-making operations, like drilling.

• Improved Error Handling

  • We now display error codes, enabling our support team to easily understand any issues, and further enhanced our messaging to assist users. 

• New Demo Parts (see the CAM Assist Panel)

  • We have two additional demo parts for you to try CAM Assist on, including a 3+2 part. 

Improvements

• Decreased the time for the CAM Assist menu to open

• Use Fractional values for imperial tool libraries

• Enable Users to press ‘Cancel’ during bulk roughing strategy production 

Fixes

• Fixed some minor cases where CAM Assist doesn’t run after installation

• Fixed a minor issue around V1.10 of CAM Assist appearing as an outdated version

• Fixed further errors around unsupported hole types

Hotfix v1.11.1

• Fixed an issue that caused Fusion to hang when the authentication page (shown during CAM Assist installation) is closed.

• Improved the tooltip for Select roughing directions for the 3+2 machining mode ‘By Setup’.
