DIFFERENCE BETWEEN SHAPER AND PLANER MACHINE EXPLAINED !!

In Shaper machine, tool is having reciprocating motion and w/p is clamped on table which is stationary. It is mostly suitable for light duty operation.In Shaping large cutting force is transferred to tool.

In Planer machine, tool is having stationary and w/p is clamped on table which is reciprocating motion. It is mostly suitable for Heavy duty operation.In planner large cutting force is transferred to table.

DIFFERENCE BETWEEN FORGING AND CASTING EXPLAINED !!

Casting and forging are both industrial processes of metal forming and shaping. Different process used in different conditions. The main difference between casting and forging is that the metal is compulsory to heat and convert 
into liquid stage in casting but in forging metal is converted into desire shape by applying pressure with or without applying heat. If the metal is preheated into forging it does not convert into liquid stage. But before differentiate this both terms; you have to know about what is casting and what is forging.

Forging vs Casting:


Difference between Forging vs Casting

What is casting?

Casting is a process in which metal is heated until molten stage and pour this liquid metal into a mold or cavity where it is allow solidifying. This process converts the metal into desire shape. It is useful to make complex structure. Most of the industrial structures parts are like lathe machine bed, milling machine bed make big base of other machinery part, IC engine components etc. are made by this process.

Advantages of Casting

  • This process can form very large structure which is impossible to form by other process.
  • It can make any complex and unsymmetrical structure.
  • The structure formed by this process has high compressive strength.
  • It can attain wide range of properties.
  • This process can attain high accuracy.

What is forging?

On the other hand forging is the process of converting metal into desire shape by applying pressure and with or without heat. When the metal is heated before applying pressure the process is called hot forging. In forging metal is heated before below critical temperature or below molten stage. Rolling, pressing, Wire drawing etc. is various types of forging. All sheets, small component, wire etc are formed by this process.


Advantages of Forging:

  • It produces tougher product compare to other.
  • The product made by forging has high impact or tensile strength.

CHECK OUT THE REASON WHY TRACTORS DO NOT HAVE SUSPENSION SYSTEM !!

First its required to get know what are things affected by a suspension system.
If a suspension is installed in a vehicle , then the vehicle will not have constant motion body. The body tend to oscillate in the direction of axis of the spring.
This oscillation can change ride height while operating . The condition may be while working or moving.Well tractors are supposed to maintain a constant depth in ploughing/digging. For this it requires the movement of the body to be restricted so that we do not disturb the main tractor functions.
If we have a suspended tractors which bounces too much over undulations in a field then we can't expect to have a constant ploughing depth which is a requirement in agriculture.
Suspensions also affects the off road stability.

As the speed of the tractor is less and the tyres big(which absorbs more shocks),the need of suspension is felt less.
