Although there is currently no dominant position, some other automakers have long been concerned about composite cast iron and magnesium. If you can't change with the dry tool technology, you can safely say that the development will cut, they first consider whether to use oil mist to cool, and then consider the water around the hard, dry, fast three words. As for oil mist cooling, it has significant advantages over sufficient cooling, including: better lubrication, avoiding thermal shock, reducing the amount of oil used to 1/60,000, and keeping the chips and workpieces dry.
In the coming years, tool manufacturers will use oil mist cooling in processability. Obviously, these manufacturers are working on new materials and new processing methods to determine the geometric angle to reduce cutting friction. The primary concern continues to be in the tool life equipment suction system to eliminate oil mist smoke and chip life and productivity.
For these reasons, technologies such as high-speed dry cutting and micro-cooling lubrication systems will further promote chipping. In addition, tool procurement methods and management methods will change to adopt faster feed rates to improve the prediction of the future, but as companies reduce tool life and control cutting heat.
It is proposed to use the low-pass digital filtering algorithm to monitor the tool breakage by using the milling torque signal. The milling torque was measured using a cutting force telemetry shank with a force sensor and an inductive power supply. The milling cutter used in the experiment was a high-speed steel spiral groove three-tooth end mill, and the workpiece material was tempered 45 steel.
