Cnc Milling: a Versatile Process

Computer Numerical Control (CNC) Milling is a common type of automated machining process. These machines are specially used for drilling, facing, and turning functions. Their classification is based on the number of axes they have. These axes are labeled as x and y for the two horizontal directions while z is for vertical movement. CNC milling is a cutting process that is used to remove metal or plastic from a block of stock material by the rotating action of the tool. The tool is moved in three (or more) directions to get the desired cut of the material.

CNC Milling machines have been programmed with the help of a set of commands called G-codes. These codes are special CNC functions in alphanumeric format.

The cutting tool is usually rotated along the axis, which is perpendicular to the table where the material to be cut is placed. There are different cutter shapes (called milling bits) such as round (ball end), square, and angled.

Advantages of CNC Milling

A large variety of 2D and 3D shapes are possible. Complex shapes from rod, block, or sheet material can be created and is cost effective for short runs.

Specifications for CNC Milling

• Rigid materials such as metals and hard plastics are used.

• Alternative machines for 2D sheet shapes that include Laser Cut, Turret Punch and fixed punch are used.

• CNC Milling requires software program tooling or work holding jigs.

• To contain costs avoid large variations in work piece height and avoid thin walls.

The CNC Machining centers are computer controlled vertical mills which can move the spindle along the Z-axis. When the machine is used in combination with conical tools or a ball nose cutter it improves the milling precision without affecting the speed thus providing an economical substitute to flat surface job that requires hand engraving.

During the milling process pressure is applied to the material therefore it is better to avoid weak shapes, long thin shapes, or ones with thin walls. CNC milling offers a cut surface that has a visible pattern due to the rotation and movement of the cutter.

CNC Milling questions?

I am doing a CNC project for CIM, and in the whole project I'm getting messed up with how to do the curve in the R of my Name. I have to work with a blue block 2" wide 3" long, and my starting coordinates are X.3Y.2

The easyest way to do it would be to start from bottom left corner of the "R". Plung in and linear interpolate up to to the top left corner(+Y). Then another linear mover to about a quarter to a third of the width of the final leter(+X). Circular interpolate a 180 degree half circle(G02). Then linear interpolate straght back to the line on the left(-X). Then Rapid out of the peice. Rapid over to the finish point of the arc. Plunge in. And linear interpolate to the bottom right corner to make the slant part(+X-Y). Then rapid up and send stuff home.

It help to drawn it on graph paper to work out the sizes. Working in incremental mode can also made it easier.
