Modifying the Perforated Pattern in CAD Application

The next step is to check the perforated pattern design on CAD software that can read DXF file format. In the case of this tutorial, ProgeCAD is used to open the perforated pattern file. From the layer management dialog box, we can see that there are 7 layers that have been created at the time the image-based perforated pattern is saved in DXF format. These 7 layers are created based on the parameters selected from the Setting Preference on Image2Punch. 

The first layer, which is “0” is a default layer. The second layer is for the cluster tool that has been used for recognition. The third layer is where the center of the cluster punch, which is the circle with radius 0.5mm (i.e. diameter 1.0mm) is kept separately from the cluster. The fourth layer is to keep center point of each tool. However, this feature is not set in this tutorial as it is not needed. As result, this layer would be contain no object. The remaining three is the layer to keep all the punch tools that have been selected to generate the perforated pattern.

Although we have enabled the Tool Hits color on the setting preference, the cluster tool is not seen in red colour but only as black as it is a default layer color. This is because Image2Punch only use the default color of any cluster tool hat has been selected as the recognition tool. In order to make the visual appearance easy to understand, changing the layer color for the cluster punch as well as its center is recommended. In the case of this tutorial, the center of the cluster tool is set to blue and the cluster tool itself is set to red.

The last step before we use the DXF file as a layout for generating the CNC code in CAD/CAM software such as Sigmanest or Jetcam, we need to turn of the unnecessary layer such as point and the “0” layer. We also need to turn of the Cluster tool layer as we do not need it as the layout. However, the layer of the cluster’s center point is so important to place the cluster tool when a CNC programmer program the CNC code based on this DXF file.

After we turn off the unnecessary layer, we need to save the file again and carry on the next step by using CAD/CAM to generate the CNC code based on particular Turret Punch machine tool.
