What does the advertising engraving machine mean to the knife?

A deep understanding of the engraving principle of the engraving machine has a clear meaning for the operator to maintain a clear tooling idea, master the tool setting operation and propose a new tool setting method. The purpose of the tool is to establish the workpiece coordinate system. The intuitive statement is that the tool is to establish the position of the workpiece in the engraving machine table. In fact, it is to find the coordinates of the tool point in the table coordinate system. For the engraving machine, the tool point must be selected before machining. The tool point refers to the starting point of the tool relative to the workpiece when the workpiece is machined by the engraving machine. The tool point can be set on the workpiece (such as the design reference or positioning reference on the workpiece), or it can be set on the fixture or workbench. If it is set at a certain point on the fixture or table, the point must be related to the workpiece. The positioning reference maintains a dimensional relationship of a certain precision.

When setting the tool, the finger position should be coincident with the tool point. The so-called tool point is the positioning reference point of the tool. For the turning tool, the tool point is the tool tip. The purpose of the tool setting is to determine the absolute coordinate value of the tool point (or workpiece origin) in the table coordinate system and measure the tool position deviation value of the tool. The accuracy of the correction of the tool point directly affects the machining accuracy. When actually machining a workpiece, the use of a tool generally does not meet the machining requirements of the workpiece. Usually, multiple tools are used for machining. When using multiple turning tools, the geometric position of the tool nose points will change after the tool change position, which requires different tools to start machining at different starting positions. Ensure that the program is working properly. In order to solve this problem, the engraving machine is equipped with the function of tool geometry position compensation. With the tool geometry position compensation function, as long as the position deviation of each knife relative to a pre-selected reference tool is measured in advance, it is input to the engraving machine. In the tool parameter correction column, the tool number can be automatically compensated for the tool position deviation in the tool path by using the T command in the machining program. The measurement of the tool position deviation is also carried out by the tool setting operation.

How does the advertising engraving machine approach the knife?

There are two main methods for how the advertising engraving machine can be used for the knife. One is the trial cutting method, the other is the automatic tool setting for the knife, and the third is the automatic tool setting.

How to use the advertising engraving machine?

1. Trial cutting method: The workbench itself has a mechanical origin. When you are knives, you should try to cut it. For example, if the outer diameter of the car is Z, the Z-direction exits, and the outer diameter of the car is measured. Find the tool number you used to move the cursor to X input X and other information... According to the measurement workbench, you know the position of the tool tip on this tool position. The inner diameter is the same, the Z direction is simple, and each knife is in Z. It is enough to touch a place and measure Z0. In this way, all the knives have a record, and it is determined that the machining zero is within the workpiece shift (offshift), and the workpiece origin can be determined by any knife. In this way, remember to read the knife before the knife. There is a more convenient method, which is to use the chuck to align the knife. We know the outer diameter of the chuck. The cutter can touch the input outer diameter. For the inner diameter, you can take a gauge block and press it on the chuck. The outer diameter of the chuck is ok.

2. Automatic tool setting for the tool setting tool: If there is a tool setting tool, it is more convenient. The tool setting tool is equivalent to a fixed tool setting test piece. When the tool touches it, it is recorded in the position. Therefore, if it is a multi-class small batch processing, it is best to buy a tool setting tool to save time.

3, automatic tool setting:

First: processing a metal block, the height of the metal block must be accurate and flat. The metal block is perforated, and a wire is attached to the first lead electrode line of the marble engraving machine.

Second: Control the inside of the electrical box to find the 15 holes of the data line. Follow the string groove to the top of the Z-axis and connect to the block. The machine ground wire and the entire machine are connected.

Third: Check if the machine ground wire is connected. The tool block is brought into contact with the engraving tool so that the circuit can be realized.

Fourth: Testing. Observe whether the I/O state of the Weihong software has a red dot turning into a green dot. If it succeeds, the Z axis will slowly drop.

Fifth: Click on the floating tool under the operation menu. When it hits the tool block, it automatically pops up to achieve automatic tool setting.
