Most methods for marking text on products have drawbacks. For example paint can chip away; stickers often wear or peel off; etched marks may not be deep enough. Text milling is a solution to all these problems. It cuts precise, durable, permanent characters straight into the material.<\/p>\n\n\n\n

In this blogpost you will learn how text milling works, discover its main benefits, get design tips and see how it is used in real world situations.<\/p>\n\n\n\n

What is Text Milling<\/h2>\n\n\n\n
\"Text<\/figure>\n\n\n\n

Basically text milling is a process of engraving text, logos, numbers onto a part using a CNC machine. In this process, a rotating cutting tool is used that follows programmed instructions to carve the design into the surface. This method creates highly accurate and permanent markings and it is therefore suitable for part numbers, logos and branding.<\/p>\n\n\n\n

Text Milling Process \u2013 Step by Step<\/h2>\n\n\n\n

The text milling process essentially transforms a digital design into a physical engraving and it is accomplished through a deliberate, multi step process. Each individual step depends on the previous one in order to maintain both quality and accuracy.<\/p>\n\n\n\n

CAD \/ Design Stage<\/h3>\n\n\n\n

First designers typically use CAD software like CorelDRAW or AutoCAD<\/u><\/a> to create the digital text designs. They then choose font styles, set exact dimensions and also specify where the text will go. After that, designers convert the text into vectors so that the design properly matches the needs of machines. What this stage does is define all important details such as character depth, height and the overall layout.<\/p>\n\n\n\n

CAM \/ Toolpath Generation<\/h3>\n\n\n\n

After the design is completely ready, the CAD file then moves into CAM software<\/a>. The CAM program, which plays an important part here, changes the design into G-code. This specialized code tells the CNC machine how to move the cutting tool, how fast to go and also how deep to cut.<\/p>\n\n\n\n

Machine Setup<\/h3>\n\n\n\n

Before actual machining starts, the operator carefully prepares the CNC machine. The workpiece is clamped securely to the table so that it does not move. The operator also installs the correct engraving tool\u2014generally a 60-degree V-bit\u2014into the spindle. Such careful setup keeps the process precise.<\/p>\n\n\n\n

Engraving \/ Milling Execution<\/h3>\n\n\n\n

With the setup fully finished, the machine then reads the G-code and begins the work. The rotating tool precisely follows the programmed path and removes material in order to engrave the text onto the surface. Automation at this stage produces uniform results.<\/p>\n\n\n\n

Post processing & Finishing<\/h3>\n\n\n\n

After milling ends, the part may still need additional finishing steps. These steps can include cleaning off coolant or chips and also deburring<\/u><\/a>  sharp edges to give a smooth finish. The result is then a professional and neat looking part.<\/p>\n\n\n\n

At RICHCONN we also provide finishes like sandblasting, anodizing or color infill. These available options make the engraved text both visually appealing as well as highly accurate.<\/p>\n\n\n\n

Design Considerations & Best Practices<\/h2>\n\n\n\n
\"Design<\/figure>\n\n\n\n

Thoughtful planning at the design stage is very important for producing text that remains durable and clear. By following the recommendations below, designers can create designs that machines can engrave easily & efficiently.<\/p>\n\n\n\n

Choice of font<\/h3>\n\n\n\n

For text, use clean and simple typefaces. Sans-serif fonts like Helvetica or Arial work best. Their even stroke widths are compatible with capabilities of cutting tools. Serif fonts should definitely be avoided. The reason is that their small decorative strokes are difficult to accurately reproduce with machining tools.<\/p>\n\n\n\n

Spacing between letters<\/h3>\n\n\n\n

Leave enough space between letters so that the cutting tool can move freely. Plan at least 0.5 mm of clearance between each character. This spacing helps produce text that is both easy to read and clean.<\/p>\n\n\n\n

Minimum sizes<\/h3>\n\n\n\n

Set the font in your CAD file to 20 points or larger so letters stay easy to read. Specify character heights between 2.5 mm and 5 mm. Aim for a text depth of about 0.3 mm. This depth does provide both good durability and visibility.<\/p>\n\n\n\n

 If you need any confirmation then Richconn provides complimentary design-for-manufacturing reviews to ensure that the spacing and depth of your chosen font can be milled dependably.<\/p>\n\n\n\n

Raised vs recessed text<\/h3>\n\n\n\n

Choose between raised and recessed lettering. Recessed text is generally less expensive and also uses less material. Raised text, on the other hand, provides better resistance to wear and is more clearly visible.<\/p>\n\n\n\n

Material surface<\/h3>\n\n\n\n

Before placing text, always check the surface finish of the part. Avoid uneven or rough areas. These surfaces can distort the engraving and also lower the quality of the final result.<\/p>\n\n\n\n

Materials Suitable for Text Milling<\/h2>\n\n\n\n

Text milling can work with many different materials. Each type of material has unique properties of its own. It is these differences that make them suitable for a variety of uses.<\/p>\n\n\n\n

Material Group<\/strong><\/th><\/th><\/th><\/tr><\/thead>

Benefits of Text Milling<\/h2>\n\n\n\n

1. Precision & repeatability<\/h3>\n\n\n\n

CNC machines engrave text with extremely high accuracy, reaching tolerances that are as close as 0.005 mm. Because every pass is computer-controlled, human error disappears and each part gets identical markings.<\/p>\n\n\n\n

2. Durability<\/h3>\n\n\n\n

Text milling creates markings by carving them directly into the part. These markings stay permanent and strongly resist wear. Unlike labels or ink-based markings, they simply do not fade or get removed over time.<\/p>\n\n\n\n

3. Aesthetic quality<\/h3>\n\n\n\n

The process leaves even depths and sharp edges so logos and text look professional and clean. This clarity increases both the component\u2019s look and its apparent value.<\/p>\n\n\n\n

4. Flexibility<\/h3>\n\n\n\n

Text milling can work with many materials which include plastics, metals and composites. Software adjustments do allow for quick design changes. The process conveniently fits both single prototypes and also large production runs.<\/p>\n\n\n\n

5. Branding<\/h3>\n\n\n\n

Brand names or permanent logos can be added to products. This directly strengthens product identity and also makes it easier to recognize the item. Moreover it helps prevent unauthorized copying of parts.<\/p>\n\n\n\n

Applications of Text Milling<\/h2>\n\n\n\n
\"Applications<\/figure>\n\n\n\n
