Basic Knowledge About CNC Milling and Machine Types

By February 24, 2021 No Comments

Computer numeric control is responsible for bringing a revolutionary change in the manufacturing process. The biggest benefit that the computer numeric control offers is the ability to mass-produce the components. Once the machine is programmed, the operating can then mass-produce more pieces at relatively higher speed with accuracy, making it an ideal option for the mass-level production needs.

CNC milling machines use the accuracy of a computerized system that enables the multi-point cutting mechanism. When the raw material is passed through the machine, then a tool moves in three-axis rotation, X, Y, and Z. It is the process that ensures that the cutting is done with precision and the final product is gained. The 5-axis CNC milling machine will operate along a three linear axis while instantaneously rotating along the two rational axes to relatively complex operational requirements. Different CNC custom parts manufacturers offer various parts according to the requirements of different operators.

CNC Milling Methods

Here are the few common CNC milling methods:

Form Milling: It is a form of milling that produces non-flat cuts, including radii, contours, and curves. Every curve will need a different kind of tool to achieve the perfect cut.

Plain Milling: Plain milling is also known as surface milling as it uses a cutting apparatus to eliminate material along with the surface of the workpiece. In this form of milling, the rotation axis is parallel to the workpiece.

Angular Milling: Angular milling positions the cutting tool’s axis at a specific angle to the surface of the workpiece to produce angular cuts as designated by design. Grooves and dovetails are the two common examples of angular milling.

CNC Milling Machine Types

The CNC milling machines are known for their versatile ability to produce multiple kinds of cuts depending on the requirements. Generally, the workpiece remains motionless while the cutting tool moves and rotates to eliminate the material and identify the design.

Here are a few examples of CNC machines

Vertical milling: Vertical milling involves a moving vertically oriented spindle, which rotates the cutting tool to eliminate the material out of the motionless workpiece. Vertical milling machine involves a spindle and a table that moves perpendicular and parallel to the axis,

Horizontal milling: Horizontal milling involves a cutting tool with a horizontally oriented spindle as it presses against the workpiece to eliminate the material out of the motionless workpiece. It is a form of milling that can deal with deeper cuts by utilizing the thick cutting apparatus.
