chips is not a simple waste left by the process.
Long and uncontrolled chips can be wrapped around the workpiece or cutting tool, disrupting the surface and causing the process to stop. Sandvik Coromant's chips control video therefore deals with the issue directly with process reliability.
When evaluating a piece, don't just look at whether the cutting tool can cut the material or not. It should also be seen where the chips is formed and where it goes. With the cutting tool running in a narrow inner area, an open screw female diameter operation does not have the same evacuation conditions.
Cutter, material and operation are selected together
Saying "We have processed this material before" is a good start, but it is not right to expect the same behavior when the quality code and state of the material changes. The cutting geometry, chips crusher, cutting conditions and cooling approach are evaluated according to practice.
The purpose of this article is not to suggest a specific end or universal cutting value. Even in materials referred to by the same name, the supply and heat treatment situation is important. Lack of this information in the bid request leads to unnecessary assumptions in the production plan.
Measure real gain with postures
When comparing the two production trials, write next to the cutting time the cleaning postures, the change of cutting tools and the need for reprocessing. A faster-looking setting may eventually lose its advantage if it leads to further interruptions.
A sample follow-up record can include part code, revision, material party, operation, used cutter tool and cause of posture so you can talk about what happened under the circumstances instead of the phrase "the bolt was bad". For safe cleaning and intervention, the machine's stopping procedure is based on.
Question to ask in terms of purchase
You don't need to ask the manufacturer for every cutting parameter. Ask instead how to maintain the critical surface, what control to perform in mass production, and how to manage material change. These connect more directly to the consistency of the delivered part.
