Ppt On Concept Of Design Of Milling Cutters

The jig and fixture are tools used for holding the work piece in a correct location for mass production. Various types of fixtures (like drilling fixtures, milling fixtures, and welding fixtures) are used in industry. The 3-2-1 method is the fundamental principle for all …

milling cutters. The workpiece can be cut into two pieces by making a very thin slot throughout the depth of workpiece. Cutting the workpiece this way be slot milling is called saw milling. Side Milling The cutter is used for milling of sides of a workpiece. Straddle Milling It is just like side milling with difference that cutting (milling ...

• The concept of computer numerical control (CNC) incorporates a wide range of machines that perform various functions. These CNC machines are designed with precisely crafted tools to aid in the production process • If CNC machine is the brain, machine tools are the limbs- converting instructions into actual action.

Design of Cutting Tools and Holding Devices Direction of Cut Figure 4.1(e) : Vise Jaws 4.3.2 Milling Fixture This holds the part in correct relation to the milling cutter. Fixture is attached to milling machine table. Milling fixture consists of the base, clamps, rest blocks or nest, locating points and gauging surfaces.

Plain milling cutters that are more than 3/4 inch in width are usually made with spiral or helical teeth. A plain spiral-tooth milling cutter produces a better and smoother finish and requires less power to operate. A plain helical-tooth milling cutter is especially desirable when milling an uneven surface or one with holes in it. Types of Teeth

In machine tools like drilling machine, boring machine, milling machine, planing machine, broaching machine and surface grinding machine the job remains fixed on the bed or work table of those machine tools. Fixtures are mostly used in the aforesaid machine tools and jig specially for drilling, reaming etc. for batch production.

Milling is done using a cylindrical milling tool mounted in a milling tool holder that is then mounted in the tool spindle on the machine. End Mills End mills are the most common milling cutters. End mills are available in a wide variety of lengths, diameters, and types. A square end mill is used for most general milling applications.

Cemented carbide tools are extremely hard; they can withstand very high-speed cutting operation. Carbide tool does not lose their hardness up to 1000° C. A high cobalt tool is used for a rough cut while low cobalt tool used for finishing operations. Cutting speed range - 60-200m/min Temperature - 1000°C Hardness – up to HRC 90 Ceramics

Design recommendation for sloshing phenomena in tanks has been added in this publication. Design spectra for sloshing, spectra for long period range in other words, damping ratios for the sloshing phenomena and pressures by the sloshing on the tank roof have been presented.

Cutting tools should have high strength, hardness even at higher or lower temperatures. It should not change any of the material properties ( ductility, hardness, strength) in the long rung. It should have high toughness and should have the ability to withstand shock and vibration. The tool should be cheap in price.

Horizontal milling machines do not use a fixed spindle, multiple cutters can be mounted on a horizontal spindle across the table when the horizontal arbor stretches across the entire length of the bed, the rotating cutting tool press against the workpiece and remove excess materials from the piece to produce the desired CNC milling parts.Some horizontal machines …

• Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm
