How to set the tool by CNC? What are the operation steps of CNC lathe tool setting?

It's good to study, so I'll study it slowly.

There are two methods of tool setting on CNC lathes: trial cutting tool setting and external tool setting instrument.

1. The operation steps of the trial cutting and knife setting:

1) Select the manual operation mode of the machine tool;

2) Start the spindle, try to cut the outer circle of the workpiece, and keep the X direction not moving;

3) stop the spindle and measure the outer diameter value of the workpiece;

4) Select the MDI operation mode of the machine tool;

5) Press the "off set sitting" button;

6) Press the "Coordinate System" soft key at the bottom of the screen;

7) Move the cursor to "g54";

8) Enter x and the measured diameter value;

9) Press the "Measure" soft key at the bottom of the screen;

10) Start the spindle, try to cut the end face of the workpiece, and keep the Z direction not moving;

2. The operation steps of the tool setting instrument outside the machine:

1) Move the reference knife so that the knife position is aligned with the center of the reticle of the microscope;

2) The relative position of the datum knife at the point is cleared, and the specific operation is to select the relative position to display;

3) The tool compensation value is cleared to zero, the specific operation is to press the "off set sitting" button, press the "Correction" soft key at the bottom of the screen, select "shape", and enter xo and zo on the tool compensation number corresponding to the reference tool;

4) Select the manual operation mode of the machine tool, remove the tool holder, and change the tool;

5) Align the knife point with the center of the crosshair of the microscope;

6) Select the MDI operation mode of the machine tool;

7) Set the tool compensation value, the specific operation is to press the "offset sitting" button, press the "Correction" soft key at the bottom of the screen, select "shape", and enter x and z on the corresponding knife complement;

8) Remove the tool holder and execute the automatic tool change instruction.

Answer: Hello, the steps of CNC machine tool setting are as follows: (1) select the manual operation mode of the machine tool; 2) Start the spindle, try to cut the outer circle of the workpiece, and keep the X direction not moving; 3) stop the spindle and measure the outer diameter value of the workpiece; 4) Select the MDI operation mode of the machine tool; 5) Press the "off set sitting" button; 6) Press the "Coordinate System" soft key at the bottom of the screen; 7) Move the cursor to "g54";

The core concept is to test an outer circle with an external turning tool, remember the current x coordinate, measure the outer diameter of the outer circle, subtract the outer diameter with the x coordinate, and enter the value into the geometric x value of the offset interface. Test run an outer circular end face with an external turning tool, remember the current z coordinates, and enter the geometric shape z value of the offset interface. The coordinate system of the workpiece is obtained by writing the tool offset value into the parameter of the tool.

CNC lathe due to the different control system, in the coordinate system establishment and reference point setting, the operation steps are different, but the CNC lathe tool setting method is basically the same, firstly, after the workpiece is clamped on the three-jaw chuck, the machine tool is operated by manual method, and the specific steps are as follows:

1) Back to the reference point operation The zero (back to the reference point) mode is used to return to the reference point to establish the machine tool coordinate system. The coordinate value of the current position of the center of the tool holder (tool setting reference point) in the machine's coordinate system is displayed on the CRT.

2) Test cutting tool setting first use the selected tool to turn a tool on the outer surface of the workpiece, keep the X-direction size unchanged, Z-direction retract, press the setting programming zero key, and the X, Z coordinate values displayed on the CRT screen are cleared to zero (i.e., X0, Z0); Then, the spindle is stopped and the outer diameter of the workpiece is measured. This is shown in Figure 2. When the X coordinate value displayed on the CRT is -(D 2), press the setting programming zero point key, and the X and Z coordinate values displayed on the CRT screen are cleared to zero (i.e., X0, Z0), and the system completes the setting function of programming zero point.

3) Establish the coordinate system of the workpiece: The current position of the tool tip (the tool position of the turning tool) is on the programming zero point (that is, the origin of the workpiece).

First, turn the workpiece with a knife, do not move the Z-axis, set it to Z zero, measure the difference with the actual size, and then punch it in the knife to make up, the X-axis is also the first to turn a knife, the X-axis does not move, and the size is measured out, and the measurement is how much x is entered.

Rely on you, brother, this problem is too big! First of all, you have to tell you what system you are, I'll give you an example, just a wide number of 928 First press the knife on the panel to make up the zero first clear Z-axis move to the first side of the workpiece flat input, IK pay attention to it yourself After OK in the outer circle of the car How much is OK in the input x It's OK If you don't worry, you can choose a single paragraph In the fast magnification slower It's not good to talk on paper I can only tell you that it's basically like this Go touch it yourself! Take a look at the manual!

A word for the family!

For example, for an external tool, if the tip of the tool touches the plane of the workpiece, enter x (outer circle value) in the tool patch where the tip of the tool touches the outer circle of the workpiece. Other knife-to-knife methods are similar!

Tool setting is divided into tool setting instrument tool setting and direct tool setting. Some of the lathes I used to work on did not have a tool setting instrument, which was a direct tool setting, and the following tool setting skills were direct tool setting.

First, select the center of the right end face of the part as the tool setting point, and set it as the zero point, after the machine tool returns to the origin, each tool that needs to be used is set to the tool with the center of the right end face of the part as the zero point; When the tool touches the right end face, enter z0 and click to measure, and the measured value will be automatically recorded in the tool complement value, which means that the z-axis is aligned.

X to the knife for the trial cutting of the tool, with the tool to turn the outer circle of the part less, measure the value of the outer circle of the car (such as x is 20mm) into x20, click to measure, the knife complement value will automatically record the measured value, then the X axis is also right;

This tool setting method, even if the machine tool is powered off, will not change the tool setting value after the power is restarted, and can be applied to the production of the same part in large quantities for a long time, and there is no need to re-set the tool when the lathe is closed during the period.
