Computer controls and automation can greatly enhance certain manufacturing capabilities. Under computer numerical control (CNC) parameters, tasks that were formerly considered impractical can be accomplished quickly and with a high degree of precision. CNC programming can be designed to match multiple production needs, allowing an automated machine to specialize in a range of fabrication projects. Despite the expanding role of computer controls, CNC-based production is still dependent on its machinery. This makes selecting the appropriate components and machine tools a priority regardless of the level of automation in a system. In the case of drilling machines, such as mills and routers, the type of drill bit used can be a significant influence on the final product. CNC programming can control the feed and depth rate in a drilling cycle, as well as the repetition of specific drilling operations, but choosing a well-suited drill bit remains the manufacturer’s decision.

In this article, we would like to discuss the elements that make up tool & high speed steels. What do these elements do to provide the mechanical and physical properties we need for our applications? The most common elements are the following: CARBON (C): this is the most basic alloying element which enables steel to harden. Carbon combines with the other elements to form hard, wear-resistant carbides. MANGANESE (Mn): controls hardenability in alloy cold work steels. SILICON (Si): improves toughness in the shock resisting steels group. Added to hot work steels to raise critical points and reduce scaling tendencies. Added to O-6 & A-10 to form graphite. CHROMIUM (Cr): controls hardenability and is added for abrasion resistance and hot hardness. TUNGSTEN (W): provides red hardness and hard wear resistant carbides that are harder than chrome and iron carbides. Also used to improve hardenability in tool & high speed steels. Combines very well with molybdenu...

Basic properties that cutting must posses are: Tool material must be at least 30 to 50% harder than the work piece material. Tool material must have high hot hardness temperature. High toughness High wear resistance High thermal conductivity Lower  coefficient of friction Easiness in fabrication and cheap Different elements used in cutting tool materials and their properties are Element Properties Tungsten Increases hot hardness Hard carbides formed Abrasion resistance Molybdenum Increases hot hardness Hard carbides formed Improving resistance Chromium Depth hardenability during heat treat hard carbides are formed improving abrasion resistance some corrosion resistance Vanadium combines with carbon for wear resistance retards grain growth for better toughness Cobalt Increases hot hardness, toughness Carbon Hardening element forms carbides Different cutting tool materials used for cutting operations in practice are high carbon steel, high speed steel, non -f...

Alloying elements are used to alter the mechanical and chemical properties of steel to give them advantages over standard  carbon steel . While there are many alloying elements used to achieve various enhanced properties, certain elements are much more common than others. These are 5 common alloying elements: 1. Chromium Chromium Chromium added to carbon steel in percentages usually greater than 11% creates stainless steel. At this percentage and greater, the corrosion resistance of a steel vastly increases and oxidation of the iron is prevented in many conditions. The iron does not oxidize because the chromium will oxidize first and form a protective layer over the steel. Chromium also helps to improve mechanical properties, even in smaller amounts. It will increase the steel’s strength, hardness, and ability to be heat treated. Common steels with high amounts of chromium include grades 439, 309, 2205 stainless steels. Grade D2 tool steel also has significant...
