CNC operators run and monitor machines, and CNC programmers create and run the codes for them. The tool is positioned using stepper or servo motors, which act on the movements based on the code obtained from the original 3D model of the part you want to create – called the G-code. In this guide, I’ll walk you through all the key points I’ve learned about CNC over the past 10 years, so you have a solid foundational knowledge to start producing successful projects. Whether it’s a custom CNC piece or something from our Etsy catalog of designs, each piece can be built based on your specifications.

This article shows you all the best ways to save time and make sure your parts are accurate when locating Part Zero. It took a huge amount of time, and in the end it cost me about $6000 all told. No, I didn’t have to pay that all up front, but you can buy a nice little Tormach for that price and be making parts right away.
CNC Routing for Custom Furniture
GRBL is a free CAM software developed to enable Arduino boards to be used to control CNC machines. GRBL has been adopted as the native controller software by several machine manufacturers in the hobbyist sector. Some problems with GRBL have been observed, including G-Code issues that have surfaced and remain unsupported, and unplanned activation of CNC machine spindles. Autodesk Fusion® offers plug-ins for a complete suite of CNC tools, making it a powerful and well-liked all-in-one solution.

This software also has many advanced parameters that make it suitable for more experienced users, so it’s a good software for growing your skills as a CNC machine operator. On the downside, it doesn’t offer backlash compensation and it doesn’t support rotation axis. Overall, it’s a great mini CNC router software option that’s simple and great for beginner CNCers. An online CNC software, Easel frees you from downloading and launching software continuously, as well as letting you easily store your designs and changes in the cloud. Easel is only improving, too, with continuous improvements and new features introduced, including v-carving, better tool paths, tiling, and new graphics added all the time. CNC programming is my passion, and everything related to mechanical engineering is my passion.
Easel offers a free version with limitations or its full premium version for $24 per month. By using five-axis technology versus conventional three-axis machining, fewer setups are required to create a part with complex geometry. With three-axis milling, contoured parts, or parts with machining on several faces require multiple setups to create the geometry. Oftentimes, with three-axis machining, complex fixtures must be made in order to hold a part in the orientation necessary to create the feature. Five-axis machining eliminates the need, and thus cost, of creating the fixtures, because the part can be held once and rotated to create complex geometries. To create a complex surface with a good surface finish, very small cuts will need to be used.
Electrical Discharge Machines (EDM machines)
In CNC machining, start-up costs are mainly connected to process planning. This step requires manual input from an expert, so start-up costs are usually relatively high when compared, for example, to 3D printing, where process planning is highly automated. They are still much lower than formative manufacturing processes though (Injection Molding or Investment Casting), which require the preparation of custom tooling. Unlike V-Carve Desktop there’s no size limit for your creations (V-Carve Pro removes these limits), and when you’re done, simply export your design to your CNC controller software. However, as a subtractive manufacturing process lots of waste is generated, and many different tools are required for more complex projects.

When creating text or lettering, the tool must be able to maintain a constant width, height, and spacing throughout the machining process. Any variation in these factors can result in a final product that doesn’t meet design specifications. Proofing the program is the last step before we actually make real cuts. The goal of proofing is to verify the program is correct and the CNC machine is setup correctly so that there will be no problems when the g-code is run for the first time. Proofing can be done either by Cutting Air (simple but very time consuming) or by using a CNC Simulator (also called a G-Code Simulator).
A general rule to help minimize the cost is to try and design using only two axes cuts, but this isn’t always possible if a certain look or functionality is required. Keeping things consistent, such as internal corner radii and tapped holes, will also help save time and money on parts by reducing the need for tool changes. Because the computer controls the machine movement, the X, Y, and Z axes can all move simultaneously to produce a range of features, from simple straight lines to complex geometric shapes. Some limitations do exist in CNC machining, and not all shapes and features can be created even with the advances made in tooling and CNC controls. Undercuts are features that cannot be machined using standard cutting tools, as some of their surfaces are not accessible directly from above.
Check out all the articles we’ve written to help you learn more about CNC. It is something you’ll do every single time you make a part. Basically, you have to tell the CNC Machine physically where the coordinates 0, 0, 0 (XYZ) are located relative to the part.
CNC machined parts have excellent physical properties, identical to the bulk material. This makes them ideal for applications where high-performance is essential. Use the table below for a rough estimate of the cost per hour of the different CNC machines.

Overall, it’s great for 2D designs and as CNC lettering software that can save you money. You can also use Inkscape to save money, as some free CNC software limits you design-wise, such as Easel’s limited number of fonts in their free version. This makes it an effective free CNC engraving software, as well as for CNC carving. With a huge market share and a favorite of many makers, Fusion 360 is a great all-in-one CAD/CAM software for CNC.
If, for example, a CNC router misses a step, a closed loop system can attempt to correct the error, or stop and prevent crashing. For complex, tall, deep, or intricate parts, 5-axis CNC machines work best. Sometimes called die sinking or spark machining as well as spark eroding, EDM machining involves electrical discharges from sparks to cut and shape parts. CNC lathes rotate spin the workpiece in the spindle (rather than the mill tool head in mills), with a fixed cutting tool slicing chips from the spinning part. CNC milling is a very accurate and versatile process suitable for a variety of applications, is able to shape metals, plastics and wood, and is also very quick.
