This Tech Tuesday will be focusing on our new Probing module and some exciting new features we offer in this module. Here is this example part file, where I have grouped all of the milling operations together first, and then I have grouped together all of the probing cycles. All of these probing cycles in this group are used for checking the measurements on the finished workpiece. The probing cycles in this part file include reviewing the measurements of the face of the part, the outer profile, the depth and width of the pocket, the width of the island, and the diameter of the holes.
The probing operation has the same workflow as creating a milling operation. To begin creating a probing cycle, you must first right-click on the Machine Setup in the CAM Tree. Select Probing from the options, then select the geometry that the probing tool will be measuring. The example image shown below is toolpath from one of the probing cycles.
In our probing operations, you simply need to select the surfaces of the workpiece you are intending to measure. In this example probing operation, I only needed to select these two outer surfaces on the outside of the workpiece. BobCAD will automatically determine the probing cycle to utilize based on the geometry selection. This probing cycle is a Web from one surface to another on the outside of a part. You also have the ability to set the clearance plane. This way the probing tool will retract high enough to avoid any collisions.
You can define your probing tool in the tool page of each probing operation. From this tool page, you can choose a different tool from the Tool Crib, go into the Tool Crib to add tools from your Tool Library, and also enter tool-specific data manually into the Tool Data Section of the page. This page will also assist in assigning Tool Numbers and Offsets, as well as Speeds and Feeds. You can enter the values for each parameter of your tool geometry, and you can also define the custom geometry of the probing tool by drawing the profile of the probing tool.
You can set the protected feedrate on this tool page as well. Protected Feedrate sets the speed at which the probe will move in protected positioning mode. In this mode the probe will stop if it comes in contact with an obstacle.
