How to calculate the tool repair of the CNC lathe, and what is the detailed explanation of the tool

x=2r(1-tgq 2)tgq r is the radius of the tip tgq is the angle of the chamfer thief 45° is 45 30 is 30 z=r(1-tgq 2) to give you an example, the length of the chamfer 45 is the chamfer of c1 The outer yard turning tool The outer diameter of the bar with an outer diameter of 20 is x=2* is approximately equal to This is the knife to make up and then the chamfer of C1 1*2+ The outer diameter minus z=r ( is approximately equal to Then the chamfer of C1 1+ The program is z0 So so. However, in general programming, just cutting chamfer outer diameter There must be a reserve in the program, which is the z distance before cutting to the end face, which is generally the distance that must be added in the program, for example: or the chamfer of C1 x=2(x1+x2)+2r(1-tgq 2)tgq=2(1+program:

So... Give me a satisfaction, if there is anything else you won't ask me again.

CNC knife repair is explained in detail, and the common method of knife repair is to add and subtract. The knife has shape compensation and wear compensation, and the new blade is generally given around in the wear and tear.

There are two data columns in the knife supplement, one is for the knife and the other is for the knife filling. Move the page to the page where the knife is repaired, and find the knife number of the knife (t0101 will put the cursor on 01). Then start to align the tool, the tip of the knife lightly touches the end face of the workpiece, and then exits in the X direction.

CNC lathe tool addition and subtraction usage

The common method of knife repair is to add and subtract. The knife is compensated for shape and wear. In general, the amount of wear and tear of a new blade is about to. There are two data fields for knife filling, one for tool setting and the other for knife filling.

1. Knife compensation is a very important concept of tool length. When programming a part, you must first specify the programming center of the part, and then you can establish the workpiece programming coordinate system, which is just a workpiece coordinate system, and the zero point is generally on the workpiece. Unlike the programmed zeros in the x and y planes, the length compensation is related to the z-coordinate, since the tool is positioned by the spindle taper without change, so the zeros in the z-coordinate are different.

2. CNC lathes, also known as CNC lathes, computer numerical control lathes are CNC machine tools with relatively large use and wide coverage in China, accounting for about 25% of the total number of CNC machine tools. CNC machine tool is a mechatronics product integrating mechanical, electrical, hydraulic, pneumatic, microelectronics and information technology. It is a kind of high-precision, high-efficiency, high-automation, high-flexibility mechanical manufacturing equipment.

3. The technical level of CNC machine tools and their proportion in the output and total ownership of metal cutting machine tools is one of the important symbols to measure the overall level of national economic development and industrial manufacturing. CNC lathes are one of the main varieties of CNC machine tools and occupy a very important position in CNC machine tools. For decades, it has been valued by countries around the world and has developed rapidly.

If the outer circle in the X direction is increased, it will be positive, if the outer circle is decreased, it will be negative, and if the thickness in the Z direction increases, it will be positive, and if it decreases, it will be negative.

In NC programming, the tip of the tool is usually used.

Imagine a point, and automatically change the coordinate axis of the machine tool according to the actual size of the tool during machining.

or the position of the tool cutter position, so that the actual machining contour and the programmed trajectory are completely consistent, so as to achieve "tool compensation".

In knife alignment, the knife is also set with an imaginary knife tip. But in the actual processing of the turning tool, due to the process or other requirements, the tip of the tool is often not an ideal point, but a circular arc, the so-called god model tool tip arc radius is the imaginary circle radius composed of the arc of the turning tool tip, in practice, all turning tools have the size of the unequal or similar tip arc, the imaginary tip does not exist in the actual processing.

Precautions for the use of CNC lathes

In the process of use, CNC machine tools should be strictly controlled within the range of their use parameters, otherwise they may cause damage to the machine tools, such as: machining centers, CNC milling machines.

The workpiece and its fixtures and auxiliary tools placed on the workbench shall not exceed the workbench'maximum load-bearing, otherwise it will cause damage to the motion guide.

Try not to overload the cutting force, otherwise it will cause damage and failure of the transmission mechanism, and more seriously, it will burn the spindle motor or feed shaft motor due to excessive current. At the same time, the natural frequencies of the machine should be avoided as much as possible.

Grinding to prevent resonance.

It affects the machining accuracy, and even causes damage to cutting tools and machine tool components.

The above content refers to Encyclopedia-CNC lathe.

1. Open the CNC tool repair function in the leakage control system of the CNC machine tool, and set the required correction amount, correction method and correction type and other parameters.

2. According to the size and processing requirements of the parts, select the appropriate cutting tool and feed rate, and start processing.

3. In the processing process, observe the machining effect according to the actual situation, such as the position of the cutting tool is found to be inaccurate or the feed is too large or small, etc., which can be corrected through the CNC tool repair function.

4. When making up the CNC tool, it is necessary to determine the direction and amount that need to be corrected, and then make corresponding adjustments through the operation interface of the CNC machine tool or the handle and other equipment until the required correction effect is achieved.

5. Carry out relevant testing and measurement to ensure that the size and accuracy of the parts meet the requirements.

If further correction is required, it can be adjusted again using the CNC tool repair function.

CNC tools are tools used for cutting in mechanical manufacturing, also known as cutting tools.

Advanced processing equipment and high-performance CNC tools can give full play to their due efficiency. Revert.

G41 is compensated to the left side of the forward direction of the tool, which is called the left tool compensation. As shown in the figure below, this is equivalent to climb milling. G42 is G41 is compensated on the right side relative to the forward direction of the tool, called the right tool compensation.

As shown below, this is equivalent to conventional milling. From tool life, machining accuracy, surface roughness.

The milling effect is better, so G41 is used more. d is the address of the tool complement, which is the memory address of the tool radius recorded in the system, and the value of the slag grinding difference followed by the tool number is the tool number, which is used to call the value of the tool radius compensation in the memory. There can be a total of 100 addresses from D01 to D99.

The values can be pre-entered in MDI at the corresponding tool number position in the in-memory tool table. For tool compensation, use G17 G18 G19 to select the tool compensation plane, and the default state is the XY plane. G40 is to cancel the radius compensation of the tool travel bridge such as the skin function, and all the instructions to cancel the tool radius compensation on the plane are, G41 and G42 are the modes.

**, they can be written off of each other.

The advantage of using the tool compensation function is that it can be programmed directly according to the size given by the drawing without considering the radius of the tool when programming, as long as the radius value of the tool is entered during the actual machining.

With the continuous improvement of people's living standards and the rapid development of the economy, people's requirements for the freshness and safety of cold chain products are also getting higher and higher. Over the years, the state has continuously introduced corresponding policies, such as: the state has announced the "agricultural products refrigerated logistics development plan", the development committee and the reform commission and the ministry of supply and marketing cooperation jointly issued the "cold chain logistics development plan" and so on.

From these, it can be seen that the state is actively creating a modern cold chain logistics system with high efficiency, low cost, low loss, safe inducing and high flexibility. At present, the technology of cold chain logistics is constantly improving, and the process of handling business is also constantly adjusted. However, judging from the current situation, there are still many problems in the management of cold chain logistics in Chinese tea enterprises, for example, the high loss of tea.

In general, the level of cold chain logistics of China's tea enterprises is not high, and there is no professional management system and systematic cold chain logistics chain. The development of cold chain logistics of Chinese tea enterprises is still in the beginning of the process, and there are still many problems to be improved.

1.Definition and characteristics of cold chain logistics.

Cold chain logistics mainly refers to the system in which frozen and refrigerated items have been stored in a low-temperature and refrigerated environment in the process of production, storage, transportation and processing and sales, so that the quality and function of the products can be completely protected. This is a first-chain system with low-temperature environment maintenance as the main core [1]. It is a system that develops with the progress of science and technology and the rapid development of refrigeration technology, which is a low-temperature logistics process based on refrigeration technology and refrigeration technology.

There are roughly three kinds of products that can use cold chain logistics: the first is agricultural products, mainly vegetables, fruits, meat, aquatic products, etc.; The second is the food that needs to be processed, mainly frozen food, meat, cooked food, and tea; The third type is mainly some special commodities, mainly some vaccines and drugs that need to be stored at low temperatures.

Summary. CNC lathe tool repair, first say the outer diameter requirements You are now the car is small, so what to do You have to return a little knife. The x-direction towards the workpiece is negative. That is, the entry is backward and positive. That is, retracting.

That is to say, if your car is 20 wires smaller, then 20 wires in the x direction will be withdrawn x wear and tear +.

In a fixed coordinate system, I align the knife like this:

Z-axis: Position the end face with three jaws, and enter the tip position data corresponding to the tool number in the tool setting parameters. (e.g. Z-20). <
