Machining and cutting process experiments
Machining and cutting process experiments are a type of metallographic analysis performed on-site in a machining or cutting process. This type of analysis is often used to ensure that a specific material has the qualities and characteristics desired by the machining and cutting process manufacturer.
For these types of experiments, the machining and cutting process manufacturer must provide specimen material. This material should be free of foreign material, prior bedding and pitting, and any other material that could interfere with the test results. Commonly used specimen materials include wrought iron, brass, copper and stainless steel.
A basic component of machining and cutting process experiments is a cutting tool. The cutting tool is usually made of carbide, and its hardness, durability and carbide grade should be sufficient to maintain a sharp cut. Sometimes, a lubricant may be used to reduce friction and to protect the cutting tool from overheating.
The cutting area may also be important in cutting process experiments. Generally, the surface should be flat and smooth in order to reduce vibration and damage to the specimen material. Additionally, a good support system should also be in place to hold the workpiece in place and to prevent the workpiece from slipping during the test.
Once the specimen material has been prepared and the cutting tool and surface selected, the metallographic analysis may begin. This process typically involves examining the sample with a microscope under different magnifications. This process allows the experimenter to look for any evidence of damage, wear or imperfections in the cutting and machining process.
The metallographic analysis should also include a study of the wear pattern and lubricant film of the specimens as they were machined and cut. Additionally, the cutting and machining process variables should be closely studied, such as the cutting speed, feed rate, tool speed, surface finishes and work-holding fixture tension.
The data collected from a machining and cutting process experiment should be concisely presented in the form of graphs, charts and tables. A summary of this data should include what affects the wear rate of the cutting and machining process, and what variables have the greatest effect on the wear rate.
Finally, the results of the machining and cutting process experiments should be used to help optimize the cutting or machining process for the best results. This can include choosing the best cutting tool for the job, adjusting the feeds and speeds of the cutting tool, or choosing a higher grade of lubricant for the cutting process. Through the careful analysis of the data, machining and cutting process experiments can be used to help improve the quality and efficiency of the machining and cutting process for any manufacturing company.
