How CNC Router Machine Works

The CNC Router Machine is a precision machine capable of cutting, engraving or shaping materials along multiple axes. The following is a systematic summary of its working principle from a professional point of view:

Production of Design Documents

Design File: Using computer-aided design (CAD) software, designers can create a variety of complex design patterns to provide blueprints for subsequent processing.

Conversion to G-code

CAM Software to Generate G Code: design files are completed, the CAD file directly into the computer-aided manufacturing (WEB CAM) software program, the program can be converted to the style file G code, that is, the CNC router “command language” for the control of the tool’s movement path, speed and direction.

Machine Setup

Material Alignment: The product to be machined is placed on the table of the CNC engraving machine and held firmly in place with a jig or vacuum table to ensure that the product does not move during the machining process.

Tool Selection: According to the material characteristics and processing requirements, select the ideal cutting tool (such as milling cutter or engraving cutter) and install it correctly on the spindle of the CNC engraving machine.

Calibration and Zeroing

First Calibrate the Position: Before machining, the operator must calibrate the machine to ensure that the tool starts from the exact position.

Absolute Zero Setting: Increase machining efficiency by setting a starting point (absolutely no factor) on the product surface as a reference point for the CNC router.

CNC Router Operation

Load G-code: The generated G-code is sent to the CNC router’s control system, which examines it and converts it directly into detailed operating instructions.

Motion Control: The CNC router uses electric motors (e.g. stepper motors or servo motors) to drive the tool along several axes.

• X-axis, Y-axis: Controls horizontal and vertical movement.
• Z-axis: Controls the depth of cut of the tool.

Deceleration Operation: The spindle rotates at high speed, driving the tool to follow a set path, making contact with the material and removing excess to complete the process.

Tracking and Adjustment.

Real-time Tracking and Adjustment:

During the machining process, the operator can monitor the cutting process in real time through the control panel. If abnormalities are found, parameters such as feed rate, spindle speed or depth of cut can be adjusted to improve machining results.

Finishing and Post-processing.

End Cycle: CNC router machine stops automatically after finishing the machining task.

Getting the Finished Product: After machining is completed, the material is removed from the table. According to the detail requirements, the finished product can be finely ground, polished or constructed and other subsequent processing to improve the top quality of the product.

How Does a Beginner Use a CNC Router Machine?

The CNC router operates via computerized digital control and can accurately machine a wide range of materials such as wood, aluminum, stone, plastics, composites and foam. It uses a 3-axis CNC bit to shape parts by removing portions of material from them by moving them simultaneously along the X, Y, and Z axes.

Let’s take a look at the basic skills a beginner needs to operate a TechPro CNC router.

Step 1: Start the CNC Router

Before you begin, make sure you have all the necessary components connected:

1. Turn on the CNC controller located on the wall using the ON/OFF switch.
2. Press the start button (green) on the machine to activate the remote control.
3. Open the dust collector (don’t forget to check the dust bag).
4. Finally, press the button (white) that starts the vacuum table to complete the start-up of the machine.

Step 2: Selecting the End Mills – Introduction

When starting a project with a CNC router, you will encounter various types of inserts known as end mills. Understanding these inserts is critical. Here are the main points you should have before starting your first project:

1. Number of flutes.
2. End mill shapes: flat, ball, and V-tip.
3. Size.

Step 3: Selecting an End Mill – Understanding Flutes

Fluted end Mills

Cutter flutes come in two- and four-flute versions, each of which has its own specific purpose. The difference between a four flute end mill and a two flute end mill is similar to the difference between a miter saw and a hacksaw. A miter saw has fewer and larger teeth for softer materials like wood, while a hacksaw has finer teeth for cutting harder materials. Keep in mind: four-flute end mills are good for harder materials (such as aluminum, redwood, and plastic), while two-flute end mills are best for softer materials (such as MDF, plywood, and cedar).

Step 4: Choosing an End Mill – Shape

In addition to the number of flutes, end mills come in a variety of shapes:

• Flat (end mill): flat end mills are great for contour cutting, slotting or drilling.
• Ball nose: Round nose ball nose end mills are great for 3D surface machining, but not for contour cutting.
• V-Bits: Sharp V-bits excel at engraving and are especially good for lettering and intricate designs.

Note: If you stumble upon a unique bit not mentioned here, do not use it before consulting a TechPro store manager or CNC router expert.

Step 5: Replacing the Blade or End Mills

If the desired end mill is already mounted on the CNC machine, check its tightness by following the steps below:

1. Secure the remote control to the stand to ensure that the spindle start button is not accidentally pressed.
2. Carefully loosen the collet on the spindle using the two wrenches provided on the CNC milling machine table – be careful not to hurt your hands!
3. Remove the old drill bit from the collet and place it in the toolbox.
4. Insert the new end mill into the collet, making sure that most of the shank is clamped. For smaller end mills, push it in until it is about 2 mm from the start of the spiral.
5. Retighten the nut/collet/end mill to the spindle, avoiding excessive force.

Step 6: Place the Workpiece on the Table

When you are ready to cut the material, check that all four vacuum zones are working properly (located under the MDF). If there are rubber strips around the edges of the vacuum zones, they will enhance the vacuum strength – this is essential for holding the workpiece firmly in place.

If the workpiece being processed is too small to fill the entire vacuum zone, use plastic plugs and shorter rubber strips to adjust.

Next, place the MDF board back on the vacuum table, place the workpiece on top, select the desired vacuum zone, and press the white button to initiate the vacuum.

Step 7: Setting the X and Y Axes

Now it’s time to set each axis to zero. Place the tip of the milling cutter on the surface in the upper left corner of the material. After confirming the new zero point, press [XY=0] and then [OK].

Step 8: Setting the Z-axis

You can set the Z-axis using one of the following two methods:

Paper Method

1. Take a standard A4 sheet of paper and place it between the workpiece and the cutterhead.
2. Carefully lower the Z-axis until it is about 5mm from the paper, then press [~] to switch to stepping motion.
3. Move closer until the tip of the cutter just touches the paper. Then press [Shift] + [XY=0] and [OK] to set the zero point exactly 0.100mm from the surface.

Tool Sensor Method

1. Place the tool sensor under the milling cutter head at the top of the material.
2. Move the cutter head down to approximately 8-10mm above the sensor plate and press [Shift] + [~] to automatically set the zero point.

IMPORTANT: Always reset the Z-axis zero point coordinates when changing the cutterhead between milling operations. There is no need to reset the X and Y axis coordinates.

Step 9: Load File

You can now load the design files from your CAD/CAM software into the TechPro CNC controller via the flash drive.

Operating Instructions:

1. Insert the flash drive into the card reader.
2. Wait for the “Reading USB” message to appear.
3. Press [OK].
4. Use ▲▼◄► to navigate through the USB library to find your files.
5. Press [OK] to upload, [1] to confirm.
6. Put on your ear muffs and goggles.
7. Finally, press Start [ ► ] to begin.

Step 10: Safety Guidelines

• Always wear goggles and ear muffs. Goggles and earplugs are provided in the workshop.
• Keep the work area clean and tidy, free of tools and clutter.
• Never leave the CNC router unattended. If you must leave it, have someone monitor it or suspend work.
• Do not place your hands or feet on the machine while it is running.
• Do not adjust or move material while the CNC Router is running.
• Use a dust collector or vacuum cleaner while the CNC router is operating.

By following these steps and safety guidelines, you will be able to successfully utilize your TechPro CNC Router.
