| Critical aspects of machining process capability for automobile spare part manufacturing (II)
 | For international buyers with limited knowledge of machining, it is important to have some basic understanding of the machining process capabilities of your suppliers of machined parts.
Focus on people, tooling, material, process control, environment, testing, recording and marking, as they are the critical elements in the quality assurance of the machined parts you are purchasing.
|
Questions on machines and tooling you should ask when you visit or audit your suppliers include: 1. | Are the machines and tooling checked daily according to the requirements? | 2. | Are preventive maintenance plan and parts plan available? | 3. | Are there statistic reports on the equipment operation rate? Is predictive maintenance implemented? | 4. | Are machining parameters for the CNC equipment under supervision? | 5. | Are fixtures and tooling checked or changed periodically and placed on-site according to standard? | 6. | Are tool change plans available? How the tools are managed? How often are the tools replaced? Any records? | 7. | Are there fixed schedules of calibrations or external appraisals for the testing equipment? Are the external organizations qualified with certifications? |

| Oil cooler
 |
The oil cooler is a device that accelerates the lubrication of the oil to keep lower temperature. In a high-performance, high-power reinforced engine, due to large heat load, an oil cooler must be installed.
The engine oil cooler (water-cooling) is placed in the water circuit, controlling the temperature of the lubricating oil with the temperature of the cooling water.
|
Primary failure modes for water-cooled engine oil coolers: 1. Blockage;
2. Cracking;
3. Pseudo soldering;
4. Leakage.
Main causes: Machine: improper welding process, unreasonable welding parameters;
Medium: improper coolant selection, corrosives mixed, uncleanness;
Material: improper material selection.
Key quality control points of the finished products: 1. External dimensions, installation dimensions;
2. Appearance: defects, bumps, accessories;
3. Air tightness test, material test;
4. Packaging: complete marking, reasonable protection.

| 8D (8 Disciplines) Problem Solving
 | Eight Disciplines (8Ds) problem solving is a systematic approach to nonconformity management and continuous improvements. Originally developed at Ford Motor Company, the 8D methodology uses a structured eight-step approach to problem solving by focusing on product and process improvement. Its purpose is to identify, correct, and eliminate recurring problems. |
The 8 Disciplines include: team formation, problem description, interim containment actions, root cause analysis, corrective actions, verification of corrective actions, preventive actions, and team and individual recognition.
The output of an 8D process is an 8D report.
8Ds has become a standard in the automotive industry, especially for the OEM supply chains. |
