Description

The Slot tool creates a simple slotting operation using various methods of input.

Inputs include:

selecting one or more faces or edges.
selecting two vertices.
entering two custom points.

The CAM Slot object is made to be part of a CAM Job.

Usage

Select the reference geometry on the model:
- one or more faces or edges.
- two vertices.
- nothing to use two custom points entered in the Property View of the Data tab: Custom Point1 and Custom Point2.
Invoke the Slot command using several methods:
- Pressing the Slot button in the toolbar.
- Using the CAM → Slot entry from the top menu.
Adjust the desired properties. Descriptions of available properties are found below.

Usage Notes

All slots:
- Both the beginning and end of a slot path can be extended or shortened. Use the `Extend Path Start` and `Extend Path End` properties.
- Use the `Layer Mode` property to cut the slot in `Single-pass` mode at final depth, or in `Multi-pass` mode using the available `Step Down` property.
- Toggle the `Reverse Direction` property to reverse the direction of the cut path.

Linear slots:
- Currently there is no capability to offset linear slots laterally (parallel to path of travel). Example: Say you have a tool diameter smaller than the width of the slot area you are clearing. Current behavior of this operation is to create a set of paths on a plane down the center-line of the designated slot, which will result in the slot volume not being fully cleared. Some users would want the operation to create multiple paths that are offset laterally to clear the entire slot area; this not directly possible, though can be achieved through using "Custom Points", see "Vertical face milling" below. Alternatively use the Pocket operation for such clearing.
- Create a custom linear slot using the `Custom Point1` and `Custom Point2` properties with no geometry selection. Example: Initiate a Slot operation in the GUI and click `OK` to save. Now locate and edit the `Custom Point1` and `Custom Point2` properties in the Data tab of the newly created Slot operation. Recompute the operation to update the path.

Vertical face milling:
- Most of the CAM tools cannot make a path on a single vertical plane since the projection onto horizontal plane has zero area (an internal limitation). The Slot operation makes this possible by selecting "Custom points" which define a line parallel to the vertical plane and suitable Depth parameters.

Arc/Circular slots:
- Creating arc/circular slots
  1. You will need to select one bottom arc of the slot. This will produce a path directly on the arc edge you selected.
  2. You will then need to edit the `Extend Radius` property in the Data tab of the operation. Using the expression editor, set it to either `OpToolDiameter / 2.0` or the negative version `OpToolDiameter / -2.0` as needed, depending on whether you selected the inside or outside arc of the slot.
  3. Recompute the operation.
  4. Keep in mind that if the toolbit diameter is not equal to the slot width, the path will not be in the correct location. In this case, adjust the value in the `Extend Radius` property mentioned above.
- Currently users are unable to create a custom arc/circular path. A third `Custom Center` property will need to be added, along with additional modifications to the code base.

Properties

Note : Not all of these Properties are available in the Task Window Editor. Some are only accessible in the Data tab of the Properties View panel for this Operation.

Base

Note: It is suggested that you do not edit the Placement property of path operations. Rather, move or rotate the CAM Job model as needed.

DatiPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
- DatiAngle: Angle in degrees applied to rotation of the object around Axis property value
- DatiAxis: Axis (one or multiple) around which to rotate the object, set in sub-properties: X, Y, Z
  - DatiX: X axis value
  - DatiY: Y axis value
  - DatiZ: Z axis value
- DatiPosition: Position of the object, set in sub-properties: X, Y, Z - with respect to the origin (or origin of parent object container)
  - DatiX: X distance value
  - DatiY: Y distance value
  - DatiZ: Z distance value
DatiLabel: User-provided name of the object (UTF-8)

Depth

DatiClearance Height: The height needed to clear clamps and obstructions
DatiFinal Depth: Final Depth of Tool- lowest value in Z
DatiFinish Depth: Maximum material removed on final pass. The height (thickness) of the last cutting level - set for a better finish.
DatiSafe Height: The height above which Rapid motions are allowed. (Rapid safety height between locations)
DatiStart Depth: Starting depth of Tool - first cut depth in Z
DatiStep Down: Incremental step down of Tool during operation

Path

DatiActive: Make False, to prevent operation from generating code
DatiBase: The base geometry for this operation
DatiComment: An optional comment for this Operation
DatiCoolant Mode: The coolant mode for this operation.
DatiCycle Time: The cycle time estimation for this operation.
DatiTool Controller: Defines the Tool controller used in the Operation
DatiUser Label: User assigned label

Slot

DatiCustom Point1: Enter custom start point for slot path.
DatiCustom Point2: Enter custom end point for slot path.
DatiCut Pattern: Set the geometric clearing pattern to use for the operation.
DatiExtend Path End: Positive extends the end of the path, negative shortens.
DatiExtend Path Start: Positive extends the beginning of the path, negative shortens.
DatiExtend Radius: For arcs/circlular edges, offset the radius for the path.
DatiLayer Mode: Complete the operation in a single pass at depth, or mulitiple passes to final depth.
DatiPath Orientation: Choose the path orientation with regard to the feature(s) selected.
DatiReference1: Choose what point to use on the first selected feature.
DatiReference2: Choose what point to use on the second selected feature.
DatiReverse Direction: Enable to reverse the cut direction of the slot path.

Start Point

DatiStart Point: The custom start point for the path of this operation.
- DatiX: X distance value
- DatiY: Y distance value
- DatiZ: Z distance value
DatiUse Start Point: Make True, if manually specifying a Start Point. Set the start point in the property data Start Point field.
