Numerical control machining is very active in various fields, including aerospace, medical, automotive, intelligent equipment, daily necessities, and other industries. However, numerical control machining uses heavy equipment, and a slight lack of attention can lead to serious consequences. So what are the reasons for mechanical processing errors?

1. Human factors

(1) Manca de concentració: Quan l'atenció de l'operador no està centrada, pot causar errors innecessaris, i en casos graves, pot danyar l'eina de la màquina i comprometre la seguretat de la vida.

(2) Misunderstanding: The operator's incomplete understanding of the processing frame can easily lead to processing errors.

(3) Error del principiant: A causa de la falta d'experiència, els operadors nous tenen tendència a error s de processament mecànic.

(4) Unexpected error: Mechanical processing errors caused by some abnormal situations, such as component failures in processing equipment, detachment during fixture processing, etc.

(5) Intentional error: The operator's intentional human error caused by certain personal reasons has a very negative impact.

2. Programming error

(1) The bottom of the coordinates is set to 0, but in actual processing, the top is set to 0.

(2) The safety height is too low, and the tool cannot fully lift the workpiece.

(3) L'obertura secundaria té menys llibertat que la anterior.

(4) Després de completar el programa, analitzar i verificar el camí del programa.

3. Error manifest de comentari del programa

(1) Escrivi el nombre de contactes d'un costat com el centre dels quatre costats.

(2) The display of the clamping distance of the caliper or the protrusion distance of the workpiece is incorrect.

(3) Quan l'anotació de la llargada de l'ejecció d'eines no és clara o incorrecta, pot provocar contacte.

(4) La llista de programes hauria d'estar tan detallada com sigui possible.

(5) When changing a single assembly, the new exchange principle of discarding old programs must be adopted.

4. Error de mesura de les eines

(1) The input of tool data does not consider the tool holder.

(2) La instal·lació d'eines és massa curta.

(3) La mesura de les eines adopta mètodes científics i intenta utilitzar instruments precisos.

(4) La llargada del ganivet és de 2 a 5 mm més llarga que la profunditat real.

5. Program transmission error

(1) El número del program a es diu incorrectament o hi ha un canvi en el programa, però ha estat processat pel vell programa.

(2) El contractant en lloc hauria de verificar les dades detalladas del programa abans de processar.

During CNC Machining, due to human or machine tool reasons, tools or tool holders are prone to collide with workpieces or machine tools. Mild cases can cause collisions between tools or machined parts, while severe cases can damage machine tool parts, causing the machine tool to lose machining accuracy and even causing personal safety accidents. Therefore, familiarizing oneself with the causes of CNC machining errors before performing CNC machining can help reduce the occurrence of errors, reduce CNC machining accidents, and improve the safety rate of CNC machining.
