Rest Pocket

Rest Pocket operations tell your router to clear the remainder of an area that has already been mostly cleared by a separate Pocket operation. The area cleared by the Rest Pocket operation is defined as the space within the outlines of designated vector graphics that cannot be reached by a specified larger clearing tool.

In the screenshot below, both shapes are assigned to a Pocket operation and a Rest Pocket operation. In the Preview simulation, the red area indicates a Pocket operation performed by a ¼" tool. The blue area indicates a Rest Pocket operation performed by a smaller, ⅛" tool.

Using a Rest Pocket operation after a Pocket operation allows you to clear the larger area with the ¼" tool more quickly than you could with the ⅛" tool, while using the ⅛" tool to clear the narrow areas along the left and right sides of the shapes that the ¼" tool could not reach.

Note

For the purposes of our demonstration, we've shown the Pocket and Rest Pocket operations running in direct succession, but you will need to perform a tool change in between running each operation.

Open vs. Closed Shapes

Because MillMage must determine the inside and outside of a shape in order to determine the area to clear, Rest Pocket mode only works with shapes that are closed. A shape is closed when it is a complete, continuous loop whose start and end points are the same. When a shape's start and end points are different, it is open.

See Open vs. Closed Shapes for more information on the difference between open and closed shapes.

Rest Pocket Mode Settings¶

Click any option in the image below to jump directly to the relevant section for that option, or scroll down for a list of options and descriptions.

Sections that have special settings for Rest Pocket operations are listed just below, while common settings that apply similarly to most or all other types of operations are listed toward the bottom.

Note

For information on options that are unique to other types of operations, see Other Operations, below.

Tool Setup¶

Clearing Tool Diameter¶

Enter the diameter of the larger tool previously used to clear the assigned shapes. MillMage will use this value to calculate which areas the larger tool was capable of reaching and clearing, and which areas remain to be cleared by the smaller tool.

Select Tool¶

Press the Select Tool button to open your Tool Library and select a tool to assign to the operation.

You must always choose a tool whose diameter is smaller than that of clearing tool, or MillMage will determine that there is no remaining area of the shapes assigned to the Rest Pocket operation to be cleared by your selected tool.

Tool Information¶

The remaining fields in this section display information about your selected tool, as entered in the Tool Library.

Tool Name¶

The name you gave the chosen tool in the Tool Library.

Diameter¶

The chosen tool's diameter.

Cut Length¶

The length of the cutting span of the chosen tool.

# of Flutes¶

The number of flutes on the chosen tool.

Clearing Pattern¶

The dropdown menu in the Clearing Pattern section controls the type of path your router will take as it clears the area within your assigned shapes.

Offset¶

Select Offset to tell your router to carve concentric paths that follow the outline of the shape(s) assigned to the operation.

Raster¶

Select Raster to tell your router to carve parallel lines in a back-and-forth motion, within the outline of the shape(s) assigned to the operation.

Two additional options are available if you select Raster mode.

Raster Angle¶

Controls the angle of the back-and-forth movements your router will make across the shape(s) assigned to the operation.

Outline Pass¶

Select whether to add an additional pass along the edges of the carved area, following the contours of the shape(s), Before or After the Raster carving is completed. You can also select No Outline.

Without an Outline Pass, Raster carvings may have stepped or flattened edges.

Cut Direction¶

Controls the direction your router will move while carving.

Conventional milling moves the router against the rotation of the spindle.
Climb milling moves the router in the same direction as the spindle rotates.

Stock to Leave¶

Enter a value here to tell your router to leave a given amount of material uncarved along the outer edges of your shape(s).

This will effectively shrink the size of the carved area inward by the amount you enter in the Stock to Leave field.

Depths and Steps¶

Equation Support and Automatic Unit Conversion

The Depths and Entry/Steps fields in the Operation Settings Editor support equations and automatic unit conversion.

For example:

To cut to a final depth of ¼ in, type 1/4 in the Diameter field, then click in another field, and MillMage will convert to the value to 0.75.

Addition (+), subtraction (-), and multiplication (*), are all also supported.
If your display units are set to metric but you've taken measurements in imperial, you can enter 1/4 in and MillMage will convert the value to 6.350 mm. This works in reverse as well, converting metric units to imperial

Multiple notations are supported, including ft, ', ", and mm.

Start Depth¶

The depth, relative to the surface of your stock, at which the operation will begin carving or cutting.

A value of 0 means it will begin at the top of your material — any value greater than 0 will tell your router to begin carving below the surface of the material.

Final Depth¶

The depth, relative to the surface of your stock, at which the operation will stop carving or cutting.

Final Depth is the total depth of the material that will be removed from your stock.

Depth Per Pass¶

Specifies the depth of material to be cleared with each pass of your router. The total number of passes is equal to Final Depth / Depths Per Pass.

For example, if you set Depth Per Pass to 1 mm, and Final Depth to 10 mm, your router will make 10 passes of 1 mm each.

Step Over¶

Step Over controls the distance between each path of your chosen clearing pattern. A larger Step Over leads to greater distance between each path.

Step Over (%)¶

Enter a percentage in the Step Over (%) field to apply a Step Over value as a percentage of your tool's diameter.

In other words, if your tool's diameter is 0.125", entering 50% in the Step Over (%) will set the Step Over value to 0.0625".

These values are linked in both directions — if you adjust the absolute value in the Step Over field, the value in the percentage field will change to indicate the Step Over value's percentage of your tool's diameter.

Entry Type¶

Entry Type controls the motion of your router as it lowers into your material down.

For Zig Zag Ramp and Plunge entries, the router lowers to the depth set in the Depth Per Pass, as it begins carving.

Plunge¶

Lowers the router straight-down along the Z Axis into the material, before the router moves in X or Y. The same Plunge movement is repeated as the router lowers for each subsequent pass.

Zig Zag Ramp¶

Lowers the router along the Z Axis into the material, while also making lateral movements along the X or Y axis, meaning the tool enters at an angle — the exact angle is determined by the Ramp Angle setting.

The same Zig Zag movement is repeated as the router lowers for each subsequent pass.

The router makes a straight down movement in Z before beginning the ramped entry.

Ramp Angle¶

Controls the angle at which your tool will enter the material, if you’ve selected Zig Zag Ramp as your Entry Type.

Step Over¶

Step Over controls the distance between each path of your chosen clearing pattern. A larger Step Over leads to greater distance between each path.

Step Over (%)¶

Enter a percentage in the Step Over (%) field to apply a Step Over value as a percentage of your tool's diameter.

In other words, if your tool's diameter is 0.125", entering 50% in the Step Over (%) will set the Step Over value to 0.0625".

These values are linked in both directions — if you adjust the absolute value in the Step Over field, the value in the percentage field will change to indicate the Step Over value's percentage of your tool's diameter.

Common Settings¶

This option requires a coolant system that is connected to your CNC's controller.

Feeds and Speeds¶

The Feeds and Speeds saved to a given tool from your Tool Library are automatically entered in the Operation Settings Editor when you select that tool.

What Feeds and Speeds should I use?

The proper Feed and Speed settings depend on your tool, machine, material, and use case. In short: there's no easy answer to that question.

For specific recommendations, the best resource is usually the manufacturer of your machine or tool.

Feed Rate¶

Controls the speed at which your CNC will move laterally (along the X and Y axes) during operations.

Ramp Rate¶

Controls the speed at which your CNC will move vertically (along the Z Axis) during ramp movements.

Spindle Speed¶

Controls the speed at which your router will rotate your tool.

Note

Not all CNCs allow Spindle Speed control through software. Some have routers which must be adjusted manually.

Plunge Rate¶

Controls the speed at which your CNC will move vertically (along the Z Axis) during plunge movements.

Coolant and Vacuum¶

Enable Vacuum¶

Enable this setting to automatically turn on your vacuum system when this operation begins.
