Command description

Top | Previous | Next


To open the Groove command, go to:


Woodwork CAM -> Groove Groove Cut icon


Once you open this command, a dialog window will appear.


Groove command dialog



To successfully run the command, the user should follow a certain sequence for specifying data. Below you will find the description of the control of the command in the sequence that needs to be followed when performing tasks in the Groove command window.



hmtoggle_plus1Selecting the spindle

Spindle selection


Using the drop-down list in the "Spindle" section, you may select a spindle and a tool. The space below contains the main data of the tool installed in the spindle. In order to see full information about the spindle, you need to click the information button Spindle Info Botton. A window for editing spindle data will appear. In this window you can also edit all data related to cutting modes (cutting feedrate, rotation speed of the spindle, etc.). The data changes can be saved in the following ways:

1. Update properties only for selected operation

2. Update properties in all operations in current technology

3. Update properties for database


hmtoggle_plus1Selecting geometry in the groove command

Pocket Selection set


For the command to be able to calculate the tool trajectories and generate an operation, you need to create a set of groove bottom surfaces to be cut. The trajectories of the saw blade tool will be calculated based on these surfaces. These surfaces are the reference geometry of the Groove operation. A flat rectangle (in Autodesk Inventor) surface may be selected as reference geometry in this command (see fig. below – a surface highlighted in red shown below in the right-hand bottom corner).


First let us discuss the case where the reference geometry consists of the surfaces of thee part body. After running the Groove command, it switches to the waiting mode and waits until a set of such surfaces is created. The following options for creating a set of surfaces are available:


1.Selection of individual groove bottom surfaces.
2.Automatic selection of groove bottom surfaces.
3.Clearing the set of surfaces.
4.A groove bottom surface expressed as a flat Autodesk Inventor surface.



Selection of individual elements


Surfaces that are suitable for the Woodwork for Inventor CAM Groove operation are those surfaces of the part model that are flat and bounded by an edge extending on at least one side and that are not narrower than the width of the saw blade. Also, these surfaces must meet the possible saw blade axis orientation in space (see fig. below). A possible vector of the tool’s spatial orientation is specified when configuring the machine’s spindles.


Groove surface


You can check if the surface can be included in the set by placing the cursor on the desired surface. Such a surface will be highlighted in white. The inclusion of the surface in the set is performed by selecting this surface with the mouse cursor. Once the surface has been included in the set, it is highlighted in blue. To remove a surface from the set, you need to select the surface while pressing and holding the "Ctrl" key.



Automatical selection Automatic selection of surfaces


This option automatically selects pocket bottoms that can be processed with a given tool.



Deselect all entities Clearing the set of surfaces


Clearing the current set of millable surfaces.



Groove bottom expressed as an Inventor flat surface


Sometimes there is a need to mill a groove or to perform a cut that is not directly expressed as a groove bottom surface of the part body. In this case, you can draw a line sketch and stretch it as a surface. In this way we will obtain geometry which can be selected as a groove bottom for the groove operation.



hmtoggle_plus1Setting the direction of cutting


Groove cut direction


Two options are available when setting the direction of cutting in the groove operation:


Climb Cut from left


Climbing cutting

The cutting tool is fed with the direction of rotation

Conventional cut from right

Conventional cutting

The feed direction of the cutting tool is opposite to its rotation


Climb cutting is always offered by default.



hmtoggle_plus1Setting the landing and withdrawal of the saw blade


Groove Saw Landing


When landing the saw blade for grooving and when withdrawing the blade from the groove, the following two options are available:


Prevent depth

Prevent groove depth

The saw blade trajectory is calculated for the selected groove surface within the model so that the groove depth in the actual part is maintained along the entire surface length.

Prevent Length

groove prevent length

The saw blade trajectory is calculated for the selected groove surface within the model so that the groove length maintained in the actual part is the same as that of the model.



Note. If the groove has an open end in the model, the command will not respond to these options at that end. At this type of the groove end, the saw blade will be used in the way as if applying the landing/withdrawal option preventing the depth of groove.



hmtoggle_plus1Saw blade overlap


Saw overlap


If the groove to be cut is wider than the width of the saw blade, an additional blade pass will be required. For this pass, you need to indicate the overlap value for the saw blade toolpath. The overlap is specified in percent from the thickness of the blade. The change of this value is not reflected in visualizing the tool trajectory in the graphic view. This, however, will have an impact on the generation of the CNC program.



hmtoggle_plus1Cleaning pass


Groove cleaning pass


You may turn on/turn off the saw blade cleaning pass to clean the groove. If the pass is on, the saw blade will travel along the groove again rotating around its axis and cleaning the shavings from the groove, at a small distance above the groove bottom. The change of this value is not reflected in visualizing the tool trajectory in the graphic view. This, however, will have an impact on the generation of the CNC program.
