Interesting Ideas for CNC Woodworking

CNC woodworking still includes some areas where manufacturers, woodworking professionals, enthusiasts, and amateurs may only have a passing familiarity with, may not have tried, or may only have heard about in the present.

The following are some sporadic hints, facts, methods, and other new discoveries in CNC woodworking (routing, machining, drilling, and other elements).


The machine control requires manual entry of some CNC woodworking programs. You will save a significant amount of time (and typing effort) by creating short sub-programs, often known as templates, particularly for repetitive scripts.

Creating an accurate angle

Use a protractor to set the angle on the machine itself if you need to cut a material at a specific angle. Next, create a program that uses an indicator to track the angle. By performing it this manner, the machine can perform the indicated task while the part is moved about.

Cutting stock

Many 2-D panel cutting programs typically handle the normal cutting tasks for panel boards. However, waste becomes an issue, particularly if the work is large enough.

To optimize the resources utilized and save waste, many professionals would use well-known 2-D panel cutting programs. Today, many professionals and enthusiasts are aware that free 1-D stock cutting programs are widely available in the market.


When making right- and left-hand pieces, mirror images work perfectly. However, when machining the mirrored portion, experts advised caution. Machining the mirrored part requires adding at least 0.01 more to the rough cutter if the previous part was programmed using G41 and climb milling.

The rationale is that you will be performing standard milling on the mirrored section. This is the area where the cutter usually penetrates the completed surface.

Machining both ends

Sometimes a job calls for you to attempt using one of the tools for the stop while also having to machine both ends of a part that is being held in a vise. Just add 1/16 to 12 the tool’s diameters before adding it to the application.

The tool/stop will then move out of the way once you bump the part against it and click the cycle start button.


Free woodworking software is widely available these days. They offer calculators that may be downloaded for free for calculating board feet, wood movements, wood selection, moisture content, drawer sizing, shelf sag rates, and many other tasks.

For doors, drawers, cabinets, furniture pieces, etc., there are systems that generate cut lists. Although there are not many fully functional free CAD applications, there are several free design apps for wood shops and cabinets.

Woodworking using CAD

The software required to create items as different as a piece of furniture or the space shuttle is known as computer-aided design (CAD). The program offers functions such as zooming, rotating, copying, stretching, and a lot more.

Some have apps for shading, texturing, and simulating three dimensions in addition to template libraries.

Since the early days of squiggly pen and paper representations of jobs and projects, CNC Woodworking has gone a long way.
