Types of cutting tools: Single-point cutting tools can be classified by their motion as linear or rotator‚ depending on whether they rotate while cutting. Linear cutting tools include tool bits (single-point cutting tools and broaches. Rotary cutting tools include drill bits‚ countersink and counter bores‚ taps and dies milling cutters and reamers. Other cutting tools‚ such as band saw blades and fly cutters‚ combine aspect of linear and rotary motion. Following are different types of cutting tools:

TYPES OF CUTTING MOTION IN MACHINE TOOLS A machine tool is a machine for making components of a given shape‚ size and accuracy as per the requirements by removing material from the workpiece by using a cutting tool to operate upon the workpiece. Machine tools are capable of producing themselves therefore the machine tools are quite often referred to as mother machine. In the manufacturing processes‚ machine tools are the most versatile and almost any product can be produced with them. The machine

HISTORY OF CUTTING TOOL MATERIALS • Cutting tool used during the industrial revolution in 1800 A.D • First cutting tool was cast using crucible method (1740) and slight hardened by H.T. • 1868: R. Mushet found by adding Tungsten we can increase hardness and tool life ( Air Quenching) • F.W.Taylor in Pennsylvania did the most basic research in metal cutting between 1880-1905 • Invented high speed steel (better H.T. process) • Better alloy

Tool control affects safety. Leaving a tool in an aircraft‚ engine or a piece of support equipment is not just an inconvenience‚ it is a safety risk. Realizing this‚ in our aircraft maintenance department superiors enforce some sort of tool control procedures. They realize that establishing and enforcing a tool control program can provide numerous benefits‚ the foremost of which is safety. The effect of Foreign Object Debris (FOD) on maintenance costs can be significant. For example‚ the cost to

State of the art on Bio-cutting fluids in Machining Submitted by: Abstract The increasing attention to the environmental and health impacts of industrial activities by governmental regulations and by the growing awareness level in the society is forcing industrialists to reduce the use of mineral oil-based metalworking fluids as cutting fluid. Cutting fluids have been used extensively in metal cutting operations for the last 200 years. In the beginning‚ cutting fluids consisted of simple

hardened tool steels (such as AISI H11‚ H13‚ and D2‚ up to 56 HRC) by commercial Ø 0.5 mm square endmills‚ it is observed that the tested micro endmills showed severe wear at an early stage of the process due to chipping off around cutting edge corners‚ resulting in unsatisfactory tool life and product appearance (burr formation). Detailed examination of current tool geometry shows that it is mainly inherited from that of macro endmills‚ making the cutting edge corners the weakest part on the tool. As
