Secondly you want to edit the “step-over” to 1.5mm and finally you want to edit the “stock offset” to 0.5mm. Firstly select the box which says “multiple depths” so there is a tick inside the box. Step 6: In step 6 you want to select “passes”. Both images below show what you setup should look like after these steps have been completed. Next you want to change each thee “offsets” to 3mm. You want to change the “from section for all three to specify “top height”. As shown below you only want to edit the top three boxes including clearance height, retract height and feed height. Step 5: In step 5 you will select the height section. This is to outline the edge of the mould. Step 5: Then go into “geometry and select your outer edge as your chain as shown below. The details of which tool to select are shown below. Step 4: In the tool section you are going to want to select you tool. Step 3: Next you are going to want to right click on your setup and click new operation, 2D milling and then face. Doing this you must select “stock” as show in the image below and add 10mm on the sides 3mm on the top and 2mm on the bottom. Next you want to add stock to the sides and bottom of your model. Additionally the “z’ axis should be pointing upwards and the origin should be at the top of the centre of the model. Move between “model” and “manufacture” as shown below.Ĭlick on setup next to “manufacture” as shown below. It makes things easier if you design your model parallel to the front-line when it comes to setting the coordinates, as shown below. For example I have created a tile to CNC. Step 1: Create a CAD model that you want to CNC. This post will show you in detail how to CNC machine one a female mould tool for a silicone resin injection. G-code stands for “Geometric code” and is a programming language for CNC that instructs machines where and how to move. CAM: define a series of cutting operations + export this as a G-code and load this into the software that runs the machine. The integration between these two softwares is called CAD-CAM. Furthermore CNC machines use computer aided software to to allow CAD models to be operated. These are machines which are digitally controlled fabrication machines. CNC stands for “Computer Numerically-controlled” machines.
