Development of Endmills for Milling Hardened Steel Molds and Copper Electrodes
In recent years, mold manufacturers have had to meet growing demand for high precision molds, low cost and short delivery time due to the miniaturization of finished products, price competition with overseas companies, and reduced model cycles. In line with these market changes, users have been gradually inclined to shift their machining methods applied to key mold parts (made of hardened steel...
متن کاملPrediction of Tool Life in End Milling of Hardened Steel AISI D2
Most published research works on the development of tool life model in machining of hardened steels have been mainly concerned with the turning process, whilst the milling process has received little attention due to the complexity of the process. Thus, the aim of present study is to develope a tool life model in end milling of hardened steel AISI D2 using PVD TiAlN coated carbide cutting tool....
متن کاملFinite Element Analysis of Hardened Steel Cutting
Hard machining, as attractive replacement for many rough and finish grinding operation, generates high cutting forces and temperature that enhance tool wear when act together. Therefore, the tool geometry and machining parameters have to be carefully optimized for a given material. Because of high cost and time consuming experimental work up-to-date advanced software for modeling and simulation...
متن کاملCopper Precipitation Hardened, High Strength, Weldable Steel
Steel containing 0.03% carbon, 1.35% copper and 0.84% nickel had yield strength in the 540-625 MPa (78-90 Ksi) range depending on thickness, ultimate tensile strength in the 625-690 MPa (90100 Ksi) range, and 25-30% elongation when air cooled after hot rolling. No brittle heat-affected zone was formed during manual or automatic submerged arc welding without pre-heating or postheating. The fract...
