Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
Snips, also known as shears, are hand tools used to cut sheet metal and other tough webs. It is a cutting tool. Workers use various types of snips, with the cutting edges being straight or curved to various degrees. The style of edge employed will depend if a straight sheer or some type of shapes cut is necessary.
For instance, when milling a material like aluminum, it may be advantageous to use a tool with very deep, polished flutes, a very sharp cutting edge and high rake angles. When machining a tough material such as stainless steel, however, shallow flutes and a squared-off cutting edge will optimize material removal and tool life.
A water jet cutting a metal tool. Because the nature of the cutting stream can be easily modified the water jet can be used in nearly every industry; there are many different materials that the water jet can cut. Some of them have unique characteristics that require special attention when cutting.
Alumina, or aluminum oxide, is also extensively used in the production of cutting tools due to its exceptional hardness and wear resistance. [2] Alumina cutting tools also have high thermal conductivity, which helps dissipate heat generated during cutting, minimizing thermal damage to both the tool and the workpiece. [3]
