In Mechanical Engineering Surface finish and the surface roughness, both are referred to same. But In general Surface finish referred as the overall texture of the surface and it is a combination of three factors. Those are surface roughness, Surface waviness, Lay. Little Confusion? Let’s get into the topic Make it Clear. We produce Machine elements […]
How to Calculate tolerance values for shaft or a hole?
In machine Design, each machine member will be mated with another machine member with the defined fit. There are the different type of fits available. They are Clearance Interference, Transition fits. These fits are controlled with some Tolerances and allowances according to some Standards. Actually, these tolerances values can be calculated. According to Indian Standard […]
Fundamental deviations for shaft and holes acc. Indian Standard system.
Fundamental Deviation of shaft and holes– Fundamental deviation is an allowance rather than tolerance. The allowance is simply the deviation between the hole minimum diameter to the shaft maximum diameter. Where the tolerance refer to either hole (Max. dia of hole-Min. Dia. of the hole) or shaft (Max. Dia. of the shaft- Min. Dia. of […]
What are Hole Basis System and Shaft Basis system?
Hole Basis System and Shaft Basis system – In the Machine design process there are different components are mated together to make the machine. These components will have a different function. Base on their type of functions there must be the type of fits between the two mating components should be determined. How actually can a […]
What are the different types of Fits in Engineering?
Types of Fits In Engineering-In mechanical engineering, Mating of two components is to be determined based on the function of the two components. Even though the fasteners make them tight but tightness between the two surfaces may be needed high in some applications wherein other applications it is not required to be that much tight. So […]
