Metal Cutting
Know All About Metal Cutting Advancements
Metal cutting, as we all know, is one of the most basic operations in all manufacturing industries. In fact, the final product and its quality depend mostly on the way metal-cutting operations have been carried out in the industry. Here, you can read all about some characteristics which directly contribute to the quality of the product.
Quality Determining Characteristics
Quality issues did not receive much importance in the early 60's. But today, with increased competition and globalization of the economy, quality is the first issue that is of utmost concern for all organizations. This matter has had a major impact on the metal cutting industry too. The production departments of these industries have revised their working schedules so that they can adopt and implement better metal-cutting operations.
The precision with which metal is cut determines its surface finish, roundness and dimensional accuracy. So it is very important to maintain a proper functioning for the cutting tools as well as ensure that the worker is appropriately trained too.
The most important parameters of metal-cutting operations include:
- Cutting rate
- Depth of cut
- Feed rate
The above-mentioned parameters also help determine the cost of metal-cutting operations. Finally the cost of the cutting operation also includes the processing cost, regrinding cost, machine usage cost and added costs due to other technological constraints. The dimensional accuracy and the final quality of the surface finish are some other aspects that are taken into consideration while determining the cost of metal cutting operation.
Laser Metal Cutting
More and more industries today are moving away from conventional metal-cutting machinery and adopting laser cutting techniques. Laser cutting is the most cost-effective method used for cutting metal sheets. Besides being cost effective, laser cutting has helped provide process flexibility and enhanced production abilities too.
The most commonly used laser cutting method involves the use of CO2 gas. The gas is used in a laser resonator and produces an output power ranging from 1.5 to 6 kilowatts. Using laser for metal cutting is one of the most cost- effective means and is the one of the main reasons why so many manufacturing units are turning to laser cutting to process their material requirement.
Current day laser machines are equipped with build-in programs in their software. These built-in programs help all laser operators perform their functions much more efficiently. The programs also offer helpful processing techniques, when required, like increasing the cutting speed and eliminating heat absorption. Further machines that are equipped with 'flying optics' enable the machine accelerate cutting speeds so that high-speed cutting of both thick and thin materials can be obtained.
Metal cutting is not what it used to be some years ago. Today new and improved cutting techniques have helped all such machines grow several times more powerful and capable.
