Investigation of machining parameter for face milling
• In our project we are going to analyze the machining parameters such as MRR,SPEED,FEED,DEPTH OF CUT and also the corresponding SURFACE FINISH for the FACE MILLING operation.
• Also we are going analyze the COST INVOLVED and MACHING TIME associated with the process.
Face Milling:
• A milling operation in which the surface of the workpiece is perpendicular to the spindle axis.
• Face milling primarily is used to mill the top surface of the part.
Face milling job and cutter
High Speed Steel properties• High Speed Steel is a multi-component alloy carbon-based steel and, as such, steel
mills manufacture HSS according to the Fe-C-X system (Iron-Carbon-X). In this system, "X" can represent one or more other elements, most commonly Tungsten plus chromium, molybdenum, vanadium, or cobalt.
• High Speed Steel exhibits a density of 8.67x1000 kg/m3 (kilograms per meters-cubed).
• A greater percentage of chromium in HSS alloys will increase its strength, while vanadium increases will improve the cutting quality and sharpness of tools and drill bits made with HSS.
• When used in tools, High Speed Steel operates at a very low thermal expansion rate of 9.7 microns per meter per degree Celsius. It also conducts heat at a very low rate.
carbide tool:
Carbide Tool Properties
• Carbide is in the range of twice that of tool steel and carbon steel. carbide is in the same range as tool steel and carbon steel.
• Tungsten carbide's low thermal expansion rate must be carefully considered when preforms are provided for grinding or EDM.
• Carbide compositions exhibit low dry coefficient of friction values as compared to steels.
• Conventional grades have sufficient resistance to corrosion-wear conditions for many applications.

Surface testing
• Surface testing machine is used by us for the measurement of all the machined surface on the material.
• The roughness should be in the range of “microns”
• The capacity of surface tester is ranges from 10 – 100 microns
