Question: Do your lab's safety training test runout, alignment, fixturing, speeds, feeds, materials, and toolpaths for your machine
We milled a part of a known size during the training to observe the runout and alignment of the machine. The measurements were taken to compare the milled part with the original design size. We also did lab’s safety training.
Link to Group Work PageTo do the group work, we started by installing the software to use for computer-controlled machining assignment. The software we used is VCarve Pro - ShopBot Edition V8.5
VCarve Pro - ShopBot Edition V8.5 is a software package designed for CNC (Computer Numerical Control) machining. It is a version of VCarve Pro tailored specifically for use with ShopBot CNC routers. VCarve Pro is known for its user-friendly interface and powerful features for 2D and 2.5D CNC machining. The ShopBot Edition of VCarve Pro includes additional features and optimizations for seamless integration with ShopBot CNC machines, making it easier for users to create and toolpath designs for their ShopBot router.
We started by downloading the software from the link here: https://portal.vectric.com/. To access the download requires login credentials of which we have, email and password used to create account.

These files can be read by VCurve where we will set the toolpath for controlled cutting with ShopBot.
The next thing was to import all the saved parts with .DXF in Vcurve software as seen in the next image.
Parts of the design in Vcurve
Using fillets tool in joints (Dog-bone)
The fillet is 1/2 of the tool diameter, here is 3mm.
Toolpath preview of all parts of my design
The tool used is End Mill (6mm), 3 passes and inputs to cut the wood
After setting all inputs then saved toolpath with .sbp extension
The machine used is ShopBot (Here is its controller)
Once you've saved the file, it automatically launches the Shopbot controller. Then, using the controller, set the origin. Turn on the CNC router switch, and secure the machine to the computer by pressing the reset button (usually blue). This allows you to control the gantry with the controller handles. Next, position the tool precisely at the origin of the sheet material to set the XYZ coordinates for the machining process.
To zero the axis (origin) on the controller panel, locate the small yellow keypad. Clicking on it opens another panel. From there, select the "Zero Axis" option, which opens a new panel for selecting the axis to be set at zero, marking the origin of the work. Choose all three axes (XYZ), click on "Zero," and then close the yellow keypad.
