Types of mechanical forces

-
A force exerted on a body can cause a change in either the shape or the motion of the body.The unit of force in SI system is the Newton(N) and CGS system is dyne.No solid body is perfectly rigid and when force are applied to it,changes in dimension occur.such changes are not always perceptible to the human eye since they are negligible. For the example,The span of a bridge will sag under the weight of a vehicle and a spanner will bend slightly when tightening a nut. It is also important for civil engineers and designers to appreciate the effects of forces on materials.Together with their mechanical properties of the materials. There three main types of mechanical forces that can act on a body.They are 1)Tensile force 2) compressive force and 3) shear force

APPLICATIONS OF BROACHING :

-
The operation of broaching was originally developed for machining small,internal surfaces such as key way in a small diameter which is relatively difficulty for slotter.Broaching is widely used in present day industry for machining a large variety of jobs which were formerly milled or shaped.

Internal broaching is used for machining and sizing of round holes,square,hexagonal,and many other shapes of holes.Internal keyways,splines and gears are easily produced by broaching.External or surface broaching is increasingly used in mass production as an alternatively to milling.It can machine plane or complex shapes easily and economically.

    We have been using Mr Benjamin financial team to help secure our first acreage block. We are happy with the professionalism In Financial Services Mr Benjamin and his loan company brings to the table with the loan rate of 2% interest rate that we use to get our loan from Mr Benjamin we are also doing a separate construction loan with them. Everything has been a breeze with the team behind Mr Benjamin which is  100%  of the way, and no question is too silly to ask. Would recommend this Loan officer to anyone looking for a loan at the low rate of 2% RIO!! Email Mr Benjamin and his team today for any kind of loan 247officedept@gmail.com      Whats-App Number  +1-989-394-3740

METHODS OF APPLICATIONS OF CUTTING FLUIDS :

-
Image
The method of application of a cutting fluid is very important and depends on the particular operation. These methods vary from hand applications such as use of brush or oil-can to high pressure applications.For high production. The following methods are used.    1)Flood method,    2) Jet method,and    3) Mist method. 1) Flood method : In this method,a reciprocating pump is used to force the coolant over the work and tool.The outlet of the pump is connected to a nozzle through flexible pipe.The nozzle can be adjusted to direct the stream of the fluid at the cutting zone.This is the most common method of application of cutting fluid. 2) jet method : In jet method,a small jet of fluid at high speed is directed at the point of metal separation from the underneath the tool.In high-speed jet system gear or vane type pump is used to maintain high pressure. 3) Mist method : In mist method,the fluid is passed through a specially designed nozzle to form very fine drop

ADVANTAGES AND LIMITATIONS OF BROACHING:

-
Broaching is an interesting machining process which is used in mass production. It has certain advantages and limitations as compared to the other machining processes.these are given below. ADVANTAGES : 1) Fast and simple process. 2)High degree of accuracy and finish is possible. 3)Any shape of profile can be easily machined. 4) Machining process is completed with one stroke of broach. 5) Life of broach tool is high. 6)Cutting temperature and tool wear is low. 7) Doesn't require a highly skilled operator. 8)Cutting force acts in the clamping direction I.e.,it doesn't tends to lift the workpiece from fixture. 9)cutting fluids can be applied more easily and effectively. 10)Most economical for mass production of components. LIMITATIONS: 1) Not economical for small quantity productions. 2)Cost of broach is high. 3) Tool grinding (broach sharpening) is difficult and expensive. 4) Not suitable to machine a surface having obstruction. 5) The work m

Tailstock

Image
The tailstock is located on right side of the bed i.e.right hand side of the operator. The main purpose of a tailstock on an engine lathe is to support free end of a work during operation.it is also used to hold tools for making holes (twist drills,reamers) adjusted along the bed of the lathe accommodate different lengths of stock.it is provided with set over screw at its base for taper turning alignment.it has cast iron body with bore to accommodate tailstock spindle,and the top portion contains the spindle,tailstock hand wheel, and a spindle clamp for locking the spindle in position. The end of the spindle has a taper bore for holding dead centre,taper shank drills and other tools.the spindle can centre,taper shank drills and other tools.The spindle can be moved in and out of the tailstock by the rotation of hand wheel in anticlockwise and clock wise direction respectively.A tailstock is shown in fig.
