CNC processing novices often encounter the situation of inaccurate points, sometimes it takes more than ten times to get accurate points. To this end, today I will introduce the reasons and solutions of inaccuracy in CNC machining.

Reasons for inaccurate CNC machining

1. The operator’s manual operation is not accurate, and the manual operation number is wrong.
2. There are burrs around the mold.
3. The center bar has magnetism.
4. The four sides of the mold are not vertical.

The solution to the inaccuracy in CNC machining is as follows:

1. The manual operation should be carefully checked repeatedly, and the points should be at the same point and at the same height as far as possible.
2. Deburring the periphery of the mould with oilstone or file, wiping it with rag, and finally confirming with hand.
3. Demagnetize the center bar before centring the mold (ceramic center bar or others can be used).
4. Check whether the four sides of the die are vertical (the verticality error is large, so we need to review the scheme with the fitter).

Points are not complex, according to the above method can operate several times, I hope to help you.

CNC Lathe Feed processing path refers to the path that the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool) until it returns to the point and ends the processing program, including the path of cutting and the path of non cutting empty travel such as cutting in and cutting out.

The feed route of finishing machining is basically carried out along the contour of the parts. Therefore, the key point of determining the feed route is to determine the feed route of rough machining and empty stroke.

In the CNC lathe processing, the determination of the processing route should generally follow the following principles.

① It should be able to ensure the accuracy and surface roughness of the workpiece to be processed.

② The processing route is shortest, the idle travel time is reduced, and the processing efficiency is improved.

③ The workload of numerical calculation should be simplified as much as possible.

④ For some repeated programs, subroutines should be used.

Advantages and disadvantages of CNC CNC CNC machining has the following advantages:

① The number of tooling is greatly reduced, and complex tooling is not needed to process complex parts. If we want to change the shape and size of the parts, we only need to modify the processing program of the parts, which is suitable for the development and modification of new products.

② The machining quality is stable, the machining accuracy is high, and the repetition accuracy is high, which can meet the machining requirements of aircraft.

③ In the case of multi variety and small batch production, the production efficiency is high, which can reduce the time of production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of the best cutting quantity.

④ It can process complex surface which is difficult to be processed by conventional methods, and even process some parts which cannot be observed.
