In CNC machining, creating precise angles and curves on the workpiece is essential for both functionality and aesthetics. The G01 G-code is instrumental in achieving this, allowing for the creation of chamfers and radii with precision.

Usage Format

The G01 G-code is used in conjunction with coordinates and, optionally, with the G41 or G42 codes for tool compensation. For chamfers, it’s typically used with an angle parameter, and for radii, with an R parameter.

Explanation

Chamfering refers to cutting away the edges of the workpiece at an angle, typically 45 degrees, to create a beveled edge. This is done using the G01 code by specifying the endpoint of the chamfer line.

Radiusing involves creating a rounded edge or corner. With G01, this is achieved by specifying the radius size and the endpoint of the arc.

Example

Here’s a text diagram and code example for creating a chamfer and a radius on a workpiece:

+-----------------+
|                 | R
|                 |←→|
|                 |
|                 |
|                 |
+---------+       |
          |       |
          +-------+
          Chamfer

G-Code for Chamfer:

G01 X50 Y25 ; Move to starting point
G01 X75 Y25 ; Straight line to beginning of chamfer
G01 X100 Y50 ; Chamfer line at 45 degrees

G-Code for Radius:

G01 X50 Y25 ; Move to starting point
G01 X75 Y25 ; Straight line to beginning of radius
G03 X100 Y50 R25 ; Clockwise arc with 25mm radius

In the diagram, the chamfer is represented by a straight line transitioning between two perpendicular faces, while the radius is shown as a curve connecting the same faces.
