Command description

To open the command for cutting the material with a saw blade, go to:

 

Woodwork CAM -> Cut Cut Icon

 

A dialog window will appear once you open the command.

 

 

Cut 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 Pocket 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 material cut 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 surfaces which indicates at which point the saw blade should cut a piece of material. The trajectories of the saw blade are calculated based on these surfaces. These surfaces are reference geometry of the Cut operation. In this command, you may also select a flat rectangle (in Autodesk Inventor) surface as a reference geometry (see fig. below).

 

First let us discuss the case where the reference geometry consists of the surfaces of the part body. After running the Cut 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 part surfaces.
2.Automatic selection of surfaces for cutting.
3.Clearing the set of surfaces.
4.A cutting surface expressed as a flat Autodesk Inventor surface.

 

 

Selection of individual elements

Surfaces that are suitable for the Woodwork for Inventor CAM Cut operation are those surfaces of the part model that are flat and their normal can make up a 180 degree angle with the tool axis and they are not bounded by other surfaces which would hinder the cutting operation (see fig. below). A possible vector of the tool’s spatial orientation is specified when configuring the machine’s spindles.

 

Cut surface selection

 

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 surfaces that may be specified as cutting surfaces in the Cut operation, taking into consideration a possible tool orientation in space. In case the processed rectangle workpiece of the part does not have oversize on the given side, it is considered that the external surfaces of the part obtained in cutting the raw material board does not require additional processing. Therefore, they are not included in the set of automatically selected surfaces.

 

 

Deselect all entities Clearing the set of surfaces

 

Clears the current set of millable surfaces.

 

 

A cutting surface expressed as a flat Autodesk Inventor surface

 

Sometimes there is a need to indicate cutting without modeling it directly in the part body. In this case you can draw the line sketch and stretch it as a surface. In this way we will obtain geometry that can be specified as a cutting surface.

 

 

hmtoggle_plus1Setting the cutting direction

 

Groove cut direction

 

Scoring Cut

 

The Cut operation has specific features that require a more complex selection of the tool cutting direction than in the case of a similar Groove operation. When sawing along the entire length of the cut, there is a risk of damaging the part surface due to the saw teeth leaving the material (see fig. below). To avoid such a situation, two passes are performed:

 

First: Scoring Pass - cutting the top surface of the part.

Second: Main Cut - final cut off to remove the piece from the part.

 

 

Cut surface damages

Prescoring cut

 

If you request a scoring pass in the command, you can adjust the cutting type both for the scoring pass and for the main cut.

 

When setting the cutting direction in the cut operation, there are two available options for each pass:

 

 


Main Cut:

 

Climb Cutting

Climbing Cutting

The cutting tool is fed with the direction of rotation

Conventional Cutting

Conventional cutting

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


 

Scoring pass:

 

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

 

By default, the user is always offered a cutting option that is consistent with the climbing cutting for the both passes.

 

 

hmtoggle_plus1Controlling the scoring cut

 

Scoring Pass control

 

The following options can be selected for the scoring cut of the part:

Prescoring cut off

Scoring Cut Off

The scoring cut is turned off.

Proescoring cut on  

Scoring Cut On

The scoring cut is turned on.

Prescoring on Half  

Scoring pass depth on half thickness of part

The scoring cut depth equals half the thickness of the processed part. If this option is not active, you can indicate a specific cut depth in the input field next to it.

 

 

hmtoggle_plus1Setting the breakthrough sawing depth

Cut Breakthrough

Sets the breakthrough value of the saw blade beyond the bottom surface of the part during the cutting operation.

 

hmtoggle_plus1Setting the sawing allowance for withdrawing the saw blade from the indicated surface

 

Cut allowace

Sets the value for withdrawing the saw blade from the cutting surface.
