This will ensure a safe and efficient working environment for both the machine and the operator.
One of the most important steps in CNC machine is setting the origin point of the workpiece. The origin point is the reference point from which all the coordinates and movements of the machine are calculated. If the origin point is not set correctly, the machine may cut in the wrong place or damage the workpiece or the tool. We will introduce CNC milling machine & CNC lathe setting as follow:

For CNC Milling

There are different methods to set the origin point of a CNC milling machine, depending on the type and model of the machine, the controller software, and the features of the workpiece. we will introduce some of the most common methods and explain how to use them.

Method 1: Using a touch probe(coming soon)

A touch probe is a device that can detect when it comes into contact with a surface. It is usually mounted on the spindle of the machine and connected to the controller. By moving the probe along different axes and directions, it can measure the dimensions and position of the workpiece and automatically set the origin point.
To use a touch probe, you need to follow these steps:
- Mount the probe on the spindle and secure it with a collet or a chuck.
- Select the touch probe function on the controller software and follow the instructions on the screen.
- Move the probe close to the workpiece using the jog mode or manual data input (MDI).
- Start the probing cycle and wait for the probe to touch each surface of the workpiece. The controller will record the coordinates and calculate the origin point.
- Remove the probe from the spindle and replace it with the cutting tool.
- Verify that the origin point is correct by moving the tool to different positions and checking them on the screen.
Method 2: Using an edge finder

An edge finder is a tool that can locate the edge of a workpiece by spinning and wobbling. It is also mounted on the spindle and connected to a dial indicator or a digital readout (DRO). By moving the edge finder along different axes and directions, it can find the center of a hole, a corner, or a flat surface and set the origin point.
To use an edge finder, you need to follow these steps:

- Mount the edge finder on the spindle and secure it with a collet or a chuck.
- Connect the edge finder to a dial indicator or a DRO and zero them.
- Move the edge finder close to the workpiece using the jog mode or MDI.
- Start spinning the edge finder at a low speed (about 500 RPM) and slowly move it towards the edge of the workpiece until it kicks off center. The dial indicator or DRO will show a sudden change in reading.
- Record this reading and divide it by two. This is half of the diameter of the edge finder. Add or subtract this value from the current coordinate to get the exact coordinate of the edge.
- Repeat this process for each axis and direction until you find all the edges you need to set your origin point.
- Remove the edge finder from the spindle and replace it with
the cutting tool.
- Verify that your origin point is correct by moving your tool to different positions and checking them on your dial indicator or DRO.

Method 3: Using manual measurement

If you don't have a touch probe or an edge finder, you can also set your origin point by manually measuring your workpiece with a ruler, a caliper, or a micrometer. This method is less accurate and more time-consuming than using a device, but it can still work for simple projects.
To use manual measurement, you need to follow these steps:

- Mount your workpiece on your machine table and secure it with clamps or vices.
- Select a point on your workpiece that you want to use as your origin point. It can be a corner, a center, or any other feature that is easy to measure and align with your tool.
- Measure this point from each edge of your workpiece using your ruler, caliper, or micrometer. Record these measurements as X, Y, and Z coordinates.
- Move your tool close to your workpiece using jog mode or MDI.
- Set these coordinates as your origin point on your controller software or DRO.
- Verify that your origin point is correct by moving your tool to different positions and checking them with your ruler, caliper, or micrometer.

For CNC lathe

One of the most important steps in operating a CNC lathe machine is setting the origin point, also known as the workpiece zero point or the machine zero point. The origin point is the reference point for all the coordinates and movements of the machine. It determines the position and orientation of the workpiece relative to the tool and the spindle.

There are different methods to set the origin point of a CNC lathe machine, depending on the type and model of the machine, the control system, and the workpiece geometry. However, the general principle is to use a dial indicator, touch probe or an edge finder to locate a known feature on the workpiece, such as a corner, a hole, or a centerline, and then enter or store the coordinates of that feature as the origin point.

Here are some common steps to set the origin point of a CNC lathe machine:

1. Mount the workpiece securely on the chuck or the tailstock of the machine. Make sure it is aligned and centered properly.

2. Mount the dial indicator, touch probe or the edge finder on the tool turret or the tool holder of the machine. Make sure it is calibrated and functioning correctly.

3. Move the tool close to the workpiece, but not touching it. Select the appropriate mode on the control panel to set the origin point. For example, some machines have a "zero return" or a "work offset" mode.

4. Use the jog buttons or the handwheel to move the tool along one axis (usually X) until it touches the workpiece. The control system will display or beep when contact is made. Note down or store the coordinate value of that axis as X0.

5. Repeat step 4 for another axis (usually Z) until it touches another feature on the workpiece. Note down or store the coordinate value of that axis as Z0.

6. Enter or store X0 and Z0 as the origin point coordinates on the control panel. Some machines may require you to enter a code or press a button to confirm or save the origin point.

7. Move the tool away from the workpiece and check if the origin point is set correctly. You can do this by moving the tool to X0 and Z0 and seeing if it matches with the feature you used to set it. You can also run a test program or a simulation to verify if the origin point is accurate.

Conclusion

Setting your origin point correctly is essential for Yornew CNC. It ensures that your machine will cut where you want it to cut and produce accurate results. There are different methods to set your origin point depending on your equipment and preferences. You can use a touch probe, an edge finder, or manual measurement. Each method has its advantages and disadvantages, so you should choose one that suits your needs best. Remember
One of the most important steps in preparing a CNC program is to define the work coordinate system (WCS) of the machine. The WCS is a reference point that tells the machine where to position the tool relative to the workpiece. The WCS can be different from the machine coordinate system (MCS), which is fixed by the manufacturer and cannot be changed.

The WCS is usually set by using a special device called a touch probe, which can measure the distance between the tool tip and the surface of the workpiece. The touch probe can be mounted on the spindle or on a separate holder. The touch probe sends a signal to the CNC controller when it contacts the workpiece, and the controller records the position of the tool at that moment.

The WCS can be set in different ways, depending on the type and shape of the workpiece and the desired orientation of the machining operations. Here are some common methods of setting the WCS:

- Using a corner or an edge of the workpiece as the origin of the WCS. This method is suitable for rectangular or cylindrical workpieces that have flat and parallel surfaces. The touch probe is used to measure the X, Y and Z coordinates of the corner or edge point, and these values are entered into the CNC program as the WCS origin.
- Using a hole or a boss on the workpiece as the origin of the WCS. This method is suitable for workpieces that have circular features or symmetrical shapes. The touch probe is used to measure the X and Y coordinates of the center of the hole or boss, and the Z coordinate of its top or bottom surface. These values are entered into the CNC program as the WCS origin.
- Using a fixture or a jig as the origin of the WCS. This method is suitable for workpieces that have irregular shapes or complex geometries. The fixture or jig is designed to hold and align the workpiece in a fixed position on the machine table. The touch probe is used to measure a reference point on the fixture or jig, and this value is entered into the CNC program as the WCS origin.
Setting the WCS correctly is essential for ensuring accuracy and quality in CNC machining. It also helps to avoid collisions between the tool and the workpiece or other parts of the machine. Therefore, it is important to follow the instructions of the machine manufacturer and use appropriate tools and devices for setting the WCS.

One of the most important aspects of CNC machining is setting the tool length offset. This is the distance from the tip of the tool to the machine's reference position, usually the spindle nose or the table surface. The tool length offset ensures that the machine knows where the tool is in relation to the workpiece and can adjust accordingly.

There are different methods for setting the tool length offset, depending on the type of machine and the controller. Here are some common steps that apply to most machines:

1. Load the tool into the spindle and secure it with the tool holder.
2. Move the spindle to a position where you can measure the tool length with a tool setter, a gauge or a probe. Make sure there is enough clearance between the tool and the workpiece or any fixture.
3. Zero the Z-axis on the machine's display or controller. This sets the current position as the reference point for the tool length offset.
4. Measure the tool length with a tool setter, a gauge or a probe and enter the value into the machine's display or controller. Some machines have automatic tool measurement functions that can do this step for you.
5. Save the tool length offset in the machine's memory or tool library. Assign a tool number to identify the tool and its offset.
