These machines cut parts and carve out a variety of shapes with high-speed spinning components.

Over at the Autodesk Pier 9 workshop, we have a decent sample of CNC machines, including: CNC Routers These days the only human intervention required for running a CNC machine is loading a program, inserting raw material, and then unloading a finished product. Of course, like all things that computers touch, automation soon followed. The process of programming a CNC machine to perform specific actions is called CNC machining.īefore CNC machines came to be, manufacturing centers were operated manually by Machinist veterans.

T01 tells the machine to use Tool 1, and S500 sets the spindle speed.Īll modern manufacturing centers will be running various Computer Numerical Control (CNC) machines to produce engineered parts.

F20 sets a feed rate, which is the distance the machine travels in one spindle revolution.

G01 indicates a linear move based on coordinates X1 and Y1.

An example looks like this: G01 X1 Y1 F20 T01 S500 G-code is easy to read once you understand the format. This is the set of instructions that controls a machine’s actions, including speed, feed rate, coolants, etc. To do this, we convert all of our machining information to a language called G-code. However, we can’t just give a machine a bunch of instructions in English. Once the model is prepared for machining, all information gets sent to a machine to produce the part physically.

Configuring nesting where the CAM system will decide the best orientation for a part to maximize machining efficiency.

Setting any required machine parameters, including cutting speed, voltage, cut/pierce height, etc.

Creating a toolpath for the model, a set of coordinates the machine will follow during the machining process.

Checking if the model has any geometry errors that will impact the manufacturing process.

Machining is the controlled process of transforming raw material into a defined shape through actions like cutting, drilling, or boring.Ĭomputer Aided Manfacturing software prepares a model for machining by working through several actions, including: Once your CAD model is imported into CAM, the software starts preparing the model for machining.

If you’re using a tool like Fusion 360, both CAD and CAM exist in the same world, so there’s no import/export required. This is traditionally done by exporting a CAD file and then importing it into CAM software. When a design is complete in CAD, it can then be loaded into CAM. In CAD, any design is called a model and contains a set of physical properties that will be used by a CAM system. Engineers will make either a 2D or 3D drawing, whether that’s a crankshaft for an automobile, the inner skeleton of a kitchen faucet, or the hidden electronics in a circuit board. The start of every engineering process begins in the world of CAD. You can design the most elegant part in your CAD tool, but if you can’t efficiently make it with a CAM system, then you’re better off kicking rocks. CAD focuses on the design of a product or part. Today, there’s no design too tough for any capable machinist shop to handle. As an industry, we’ve spent years building and refining the best manufacturing machinery around. These three components are glued together with tons of human labor and skill. Post Processing converts toolpaths into a language machines can understand.Machinery that can turn raw material into a finished product.

Software that tells a machine how to make a product by generating toolpaths.What is CAM? Computer Aided Manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process.īased on that definition, you need three components for a CAM system to function: What happens behind the scenes? Keep reading, and you’ll find out. When you need something made, not just designed, CAM is your answer. We’re the ones that give the power of flight to airplanes or the rumble of horsepower to automobiles.
