In the machining process, common quality problems include:
1. Dimensional deviation: Dimensional deviation of machined parts is a common quality problem, which may be due to tool wear, lack of machine accuracy, improper setting of process parameters, etc. Dimensional deviation may result in parts not being installed or used correctly.
2. Poor surface quality: Surface quality problems such as surface roughness, scratches, and wear may affect the appearance and function of the part. These problems may be caused by improperly set cutting parameters, tool wear, and improper material selection.
3. Internal Quality Problems: Internal quality problems such as internal defects, porosity, inclusions, etc. may lead to problems such as lack of strength and susceptibility to fracture of the part. These problems may be caused by poor material quality, improper temperature control during machining, and so on.
4. Machining errors: Machining errors may be caused by improper setting of process parameters, insufficient skill level of operators, insufficient precision of equipment, etc. Machining errors may lead to problems such as inaccurate part size and irregular shape.
5. Machining residues: The residues such as chips and swarf generated during machining may adhere to the surface or inside of the part, affecting the quality and function of the part. Machining residues may be caused by improper setting of cutting parameters, tool wear, etc.
For the above common quality problems, it is necessary to prevent and solve them by optimizing the machining process, strengthening quality control, improving the precision of the equipment, strengthening employee training and other measures to ensure that the quality of machined parts meets the requirements.
