Best Coding Language for a Machining Job on a CNC Drilling Machine

A CNC Drilling machine is one type of several computer numerical controlled machines used to fabricate parts and components made of different materials. Similar to a robot, this machine drills material based on a computer code that a skilled operator enters into a computer. By following the instructions provided, the CNC drilling process produces what the customer orders and to exact specifications.

The drilling operation on a CNC drilling machine is a cutting process. Using a unique drill bit, holes of a circular cross-section get cut into the workpiece. In most instances, the bit is a rotary cutting tool with multiple points. As the drill bit presses against the workpiece, it rotates at high speeds that range between hundreds and thousands of revolutions per minute. The outcome is precision-drilled holes that benefit many industries and for a multitude of applications.

For the CNC drilling process to do what it needs to do, it follows instructions written in a computer language. As for drilling, most operators enter either a G or M code. Of the two, the G code is often considered the best. It is important to note that there are several variants of this language that primarily revolve around tool offsets. However, CAD software, including AutoCAD, PTC, and others, all output G codes that work with most CNC controllers.

G00 – Rapid movement in a linear path
G01 – Linear movement at a prescribed feed rate
G02 – Clockwise arcing movement at a feed rate
G03 – Anti-clockwise movement along an arc at a feed rate
G80 – Cancel cycles
G81 – Drill cycle
G82 – Drill cycle with dwell
G83 – Peck drilling cycle
G90 – Absolute programming
G91 – Incremental programming

As for M code language, here are a few examples:

M00 – Program stop
M01 – Program optional stop

As you can see, there is a definite learning curve when it comes to the various codes used for a drilling operation on a CNC machine. For this reason, top fabrication companies utilize the services of highly-trained, educated, and experienced professionals to ensure that any CNC machining, including drilling, gets performed to specific standards to ensure the customer’s 100 percent satisfaction with the finished part or component.
