B.3.1.2 Define mount points

  1. After saving the CAD model go to Property window.

    ../_images/tut73.png

  2. Click on the values of Mount point to edit them.

    ../_images/tut3.png

  3. Enter the coordinates for the location as shown below > Click on Apply.

    ../_images/tut70.png

  4. Check the View button as shown below to view Mount point on the model.

    ../_images/tut711.png

    Mount point are now defined on the model and can be visualized as:

    ../_images/tut72.png

B.3.1.3 Check and correct normals

  1. Click on the option Show orientation from the Ribbon bar under Render mode group.

    ../_images/tut601.png

  2. Select an assembly or a face of the imported CAD model for which you want to check the normals.

    ../_images/tut74.png

  3. Identify the faces whose normals are not oriented outward.

    ../_images/tut75.png

  4. Select the incorrect faces one by one and click on the Reverse button from Property window to correct the normals.

    ../_images/tut631.png

    The corrected normals of the window frame are shown below:

B.3.1.4 Shape extractions

B.3.1.4.1 Extract surface

  1. Right click on Shape extractions and click on Extract surface.

    ../_images/tut77.png

  2. Click right on the created surface and click on Select.

    ../_images/tut47.png

  3. Extract surface from the model and then click on tick.

    ../_images/tut79.png

    Surface is now extracted with the name Surface 1 as shown below:

    ../_images/tut80.png

B.3.1.4.2 Extract boundary

Boundary will be already extracted by Artist Studio but user can define their own boundary also. In this tutorial let us extract our own boundary.

  1. Click right on the Shape extractions and click on Extract boundary.

../_images/tut104.png

  1. Click right on the created boundary and click Select from Property window as described previously.

../_images/tut105a.png

  1. Extract boundary from the model and then click on tick.

    Boundary is now extracted with the name Boundary 1.

    ../_images/tut106.png

B.3.1.4.3 Extract master curve

For this tutorial, let us define the same edge as a Master curve which is previously extracted as a boundary.

  1. Click right on Shape extractions and click on Extract curve.

    ../_images/tut107.png

  2. Click right on the created curve and click on Select from Property window as described previously.

    ../_images/tut81a.png

  3. Extract the Curve from the model and then click on tick.

    A Curve is now extracted with the name Curve 1.

    ../_images/tut112.png

B.3.1.5 Create tape

  1. Right click on Tape types and click on Create tape.

    ../_images/tut83.png

  2. Tape is now created with the name Tape 1. The user can edit Thickness and Width by changing their values in Property window.

    ../_images/tut15b.png

B.3.1.6 Create patch type

  1. Right click on Patch types and click on Create patch.

    ../_images/tut161.png

  2. Artist Studio has created a patch with the name Patch type 1.

  3. In property window,

    • select Tape of the patch.

    • select Shape of the patch

    • edit Length of the patch.

    ../_images/tut84.png

B.3.1.7 Create laminate

The Patch laminate is the root element in the hierarchical structure i.e laminate -> stack -> layer -> sublayer -> chain -> patch.

To create laminate, follow the following steps:

  1. Create patch stack

    1. Right click on Laminate and then click on Create patch stack.

      ../_images/tut109a.png

    2. Stack is created with the name Stack 1 and entities as shown:

      ../_images/tut191.png

  2. Create patch layer

    1. Right click on Stack 1 and then click on Create patch layer.

      ../_images/img201.png

    2. Layer is created with the name Patch layer 1.

  3. Generating layup

Property window of the created layer (Layer 1) as shown below consists of various entities for generating layup.

../_images/tut91a1.png

Follow this step-by-step approach to generate layup in Patch Artist:

  1. Click on the entity Surface and select a surface from the drop-down list where you want to generate Slave curves.

    ../_images/tut21.png

  2. Click on the value of next entity Master curve and select Master curve from the drop-down list.

    ../_images/tut22.png

  3. Click on the value of entity Patch type and select a patch type from the drop-down list which you have created previously.

    ../_images/tut23.png

  4. Create Slave curves

    Click on the drop-down button to change default parameters of Slave curves. Enter the values for Number of sublayers, Sublayer offset positions, offset width and turn On or Off Trim edges at turning point and then click on the Create button.

    ../_images/tut110.png

    Slave curves are created as shown in the figure below: .. image:: img/tut111.png

  5. Modify curves

  • Select the Patch boundary.

  • Enter the appropriate values for the entities Maximum layer width, Minimum curve length, Intersection Tolerance. After this click outside property window or press enter to modify Slave curves.

  • Click on Trim button to trim Slave curves intersection with boundary.

    ../_images/tut113.png

Modified Slave curves are shown as:

../_images/tut111.png

  1. Create patches

    Click on the drop-down button to make changes in the default settings and click on the Create button to generate patches.

    ../_images/tut931.png

    Patches are generated as shown below:

    ../_images/tut114.png

  1. Optimize layup

    Click on the Run button to optimize layup. You can make changes here depending on the requirements and quality required.

B.3.2.2 Create deposit matrix

Enter here values for Deposit matrix to set the location of Positioner and Picker axes.

  1. Click on Robot settings under Miscellaneous group.

    ../_images/tut100.png

  2. Enter values for Deposit frame from Patching tab and click on the Save button.

B.3.2.3 Create Machine data

  1. Right click on Machine data and select Create machine data set.

    ../_images/tut361.png

  2. A dialog will appear for creating the machine data .

    ../_images/tut3711.png

  3. After choosing the appropriate settings click on the Create data button.

    ../_images/tut3911.png

  4. To make changes Right click on the created dataset and select Recreate machine data set.

    ../_images/tut3811.png

  5. Right click on dataset and click on the option - Optimization.

    ../_images/img3412.png

    And then click on Optimize movements.

B.3.2.4 Simulation

View simulation of the robot movements by playing Motion controller from Ribbon bar. You can visualize how positioner and picker axes are generating layups on the CAD model.
