Mill Slot

For Rotary Slot see Rotary Slot - Universal in the Rotary chapter.

The Mill Slot block creates a line or arc shape of any width. The slot is defined by a line or an arc segment and a width. The ends of the slot can be round or square.

   Arc Slot

Milling begins at the center of the bottom wall of the slot, assuming the shape is parallel to the X axis (Angle field is set to zero). The same relative “bottom” wall is maintained when the shape is rotated, so when the Angle field is nonzero, milling begins on the side that would be parallel with the X-axis if the Angle was zero:

Mill Slot Programming

  1. From a New Block screen, select the Milling softkey.

  2. Select the More softkey.

  3. Select the Slot softkey. The Mill Slot screen contains three tabs: Start, Geometry, and Caps.

To use pocketing with Mill Slot, the UltiPockets option must be installed. See UltiPockets for more information.

Start tab

Define the slot shape, width, and common starting information on the Start tab:

Some fields may be automatically calculated when sufficient data has been entered. The CAL notation appears before the field.

Geometry tab

The fields that appear on the Geometry tab depend on the slot shape selected in the Start tab (line or arc). Define the slot geometry:

Caps tab

The slot ends are defined on the Caps tab:

If a Corner Radius exceeds 1/2 of the slot width, WinMax will find the intersection point to close the contour.

 

The Field Name Glossary contains definitions of all WinMax fields. The fields listed below appear on the Mill Slot screen. Fields displayed on screen may vary according to machine type, configuration, parameter settings, and/or settings in other fields.

Start Cap and End Cap specify the type of ends the slot uses:

  • Line closes the slot with a straight line, passing through the programmed endpoint:

  • Append Arc appends an arc at the ends of the slot length, i.e., center of semi-circle is programmed endpoint:

  • Include Arc includes the arc in the slot length, i.e., outermost edge of semi-circle is programmed endpoint:
