Cookie : Options and Results

Required Step 1

1. Pick a planar wire or a face.

   Use the Single screen parameter to toggle between the Single or Multi (use only with "By Point") options that allow you to select one or multiple planar wires or faces. 

   Single / Multi (use only for "By Points")

   Single Pick a planar wire or a face. This is the default option. ExampleExample The next step (Required Step 2) is displayed automatically. Multi (use only for "By Points") Pick multiple planar wires or faces. The Multi option is used together with the By Points option (in Required Step 2) to select multiple entities and to relief all the internal sharp corners at once. After picking all entities, press <exit><exit>(middle mouse button) to proceed to the next step (Required Step 2). The multiple planar wires or faces can either be picked individually or By Box. ExampleExample Notes: The wires/faces cannot be on the same plane. If more than one wire or face is selected, only the By Points option is available in Required Step 2 (for picking sharp corners).

Required Step 2

1. One of the following groups of parameters are displayed. (Toggle between By Points and By Edges to display the appropriate parameters.) Depending on the option selected, either pick a sharp corner or pick the edge(s) from which you wish to create a cookie.

   By Points parameters This is the default toggle option.

   The By Points option is a cookie used to relief internal corners of pockets for Mold sliders and inserts or pockets for die plates. If this option is selected, pick a sharp corner from which to create the cookie. ExampleExample Pocket with internal sharp corners   Pocket with cookies

   By Edges parameters

   The By Edges option is a cookie (or overcut) used as a method in Die manufacturing that allows users to achieve sufficient overlapping between two adjacent trimming punches. If this option is selected, pick the edge(s) from which to create the cookie. ExampleExample The strip shown below requires a punch on the GREEN area. However, since such a punch is too large, it is necessary to create two or three adjacent trimming punches.

   Notes:

   • If more than one wire or face is selected in Required Step 1, only the By Points option is available in this step.

   • If you edit a cookie(s) created using the By Edges parameters and subsequently select multiple wires or faces, all the By Edges parameter settings are cleared and only the By Points parameters will be available.

   When the sharp corner/edge(s) is selected, a preview of the cookie is displayed. This preview reflects the options selected and the defined parameters settings. In addition, when an edge is selected, the preview also enables you to control the shape of the cookie by accepting or rejecting cookie flags,.

   When an edge is selected, a cookie flag is automatically displayed at both ends of the edge. The default option is to accept all cookie parameter settings at both ends.	If required, click a flag to toggle it to reject all cookie parameter settings (except Offset Value).

   By Points parameters

   The By Points option is a cookie used to relief internal corners of pockets for Mold sliders and inserts or pockets for die plates.

   

   By Points	This is a toggle option: By Points / By Edges. By Points: Create a cookie(s) by picking points. Pick one or more sharp vertices on the input wire (face). In the example below, only the vertices with the RED circle are potential candidates for selection (the other vertices are smooth). ExampleExample Of the sharp vertices, only those that create an angle larger than 180° on the outer side of the closed wire are selected. For example, in the example below, all the GREEN sectors have more than 180° (outer angle) and only their vertices will be selected (the RED sector vertices are not selected). ExampleExample The result in this case (if all 3 sharp vertices with a > 180° outside angle are selected) is the outer contour that was created as if we were merging the bounded face of the original wire with the circle (see the Diameter example below).
   Diameter	Define the diameter of the circles that will be created on each of the selected vertices. ExampleExample
   Move Center Point By	Define the distance to move the center point of the circles created on each of the selected vertices. The direction of movement for each center point is towards the inner angle, and the angle of movement is half the inside angle of the vertex. In other words, if the inside angle of a vertex is 170°, the center point of the circle would be moved the defined distance at an angle of 85°. A negative angle value cannot be given. ExampleExample
   Remove Original / Keep Original	This is a toggle option: Remove Original / Keep Original. ExampleExample Remove Original Remove the original wire entity. Keep Original Keep the original wire entity.

   By Edges parameters

   The By Edges option is a cookie (or overcut) used as a method in Die manufacturing that allows users to achieve sufficient overlapping between two adjacent trimming punches.

   

   By Edges	This is a toggle option: By Points / By Edges. By Edges: Create a cookie(s) by picking edges. Pick a single edge and the system automatically selects all "smooth" edges to the picked edges.
   Circle	Dropdown list containing the following options. Option DefinitionsOption Definitions Circle Create a rounded cookie with a diameter value parameter setting. Using this option: If the Offset Value > 0, the selected edges are offset and trimmed/extended with the side edges (as described below for Extend). Two circles are created. Rounds are added if the Radius > 0. ExampleExample Extend Create a extended cookie with a draft angle value parameter setting. Using this option: The selected edges are offset outside by the Offset Value parameter (using sharp edge - linear extension). The side edges are linearly extended. The offset and linear extensions are trimmed/extended. Rounds are added if the Radius > 0. ExampleExample In the example below, the RED edges are selected. All the selected edges are offset by the required Offset Value. The side edges are extended linearly to the offset edges. If a Radius is defined (> 0), the result would be as follows: Notes: If the Offset Value = 0, the radius is created on original sharp vertices (edges). If the Offset Value = 0 and Radius = 0, the function complete the operation but no change occurs. Advanced Create a cookie with advanced parameter settings. Using this option: Similar to the Circle option, however, instead of a circle, a trimmed offset is created. ExampleExample Enables you to define multiple radius values for the cookies. In this case, the Radius parameter is replaced with the Single Radius / Multi Radius toggle parameter. ExampleExample Single Radius produces the same results as the Radius parameter (see below). Multi Radius enables you to define multiple radius values for the cookies.   Corner Create a rounded cookie with a corner radius value parameter setting. Using this option: The Corner Radius can be defined (see the Corner Radius parameter below).
   Side Overlap	This parameter appears under the Circle and Advanced options. Define the side offset from the picked edge(s). ExampleExample
   Length	This parameter appears under the Advanced option. Set the length of the cookie if required. ExampleExample
   Offset Value	This parameter appears under all the options: Circle, Extend, Advanced, and Corner. Define the offset from the picked edge(s); negative offset values can be applied. Extend exampleExtend example Circle exampleCircle example
   Draft Angle	This parameter appears under the Extend option. Set the draft angle if required. ExampleExample Note: This option is disabled if a negative or zero offset value is applied.
   Diameter	This parameter appears under the Circle option. Set the diameters of the circles at either end of the offset. ExampleExample
   Corner Radius	This parameter appears under the Corner option. Define the corner radius value. ExampleExample Corner Radius = 2 Corner Radius = 3 The image below shows the difference between Corner Radius and Radius. Compare this picture with the one above.
   Radius	This parameter appears under all the options: Circle, Extend, and Advanced. Define the radius value. Extend exampleExtend example Circle exampleCircle example
   Remove Original	This toggle option appears under all the options: Circle, Extend, and Advanced. See the explanation under By Points parameters.

Optional Step 1

1. You can add radii at the remaining sharp edges of the new wire created after you completed the Required Step 2. Small hexagons appear on these sharp edges.

   The available options from the dropdown list are:

   

   Set the parameters as required.

   None

   Do not create radii.

   Add Radius

   Add radii. The following parameter is displayed: Global Radius Set a global radius for all the remaining sharp edges of the new wire. Either set a global radius for all the sharp edges or pick the hexagons on the sharp edges where you wish to set a specific radius. In the latter case, a dimension box appears at each picked hexagon displaying the radius value. Global Radius set to 0. Global Radius set to 4. The radii of all the sharp edges are affected; they all have the same radius. To set a radius for a specific sharp edge, pick the appropriate hexagon and... set the required radius value. Only the selected edge is affected; it acquires the defined radius value.

2. Click OKOK or ApplyApply in the Feature Guide to complete the function.
