4.4.1.1 High speed steel. In a drilling application, HSS material is normally used due to its cheaper price from other materials like tungsten carbide, ceramic or PCD. Liu et al. [29] reported in their review study of drilling composite laminates that HSS or carbide drill bits have primary attraction based on better performance at high cutting ...


Figure 3 shows generally accepted cutting speeds in high-speed machining of various materials [2]. For instance, a cutting speed of 500 mlmin is considered high-speed machining for alloy steel, whereas this speed is considered conventional in cutting aluminum. Major advantages of high-speed machining are reported as


6. Possible Defects. 7. Design Rules. 8. Cost Drivers. Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material ...

Generally stated the milling strategy with high speed mills will not follow the same path as a conventional, commodity (non-high-speed) milling machines. The ability to use smaller tools faster, cleaner, and at high feed rates, allows for multiple passes with a shorter cycle time than standard commodity machining practices.
