Surface unevenness Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surface Unevenness = 1.11*(Metal Removal Rate^0.384)
S_sd = 1.11*(Z_w^0.384)
This formula uses 2 Variables

Variables Used

Surface Unevenness - (Measured in Meter) - Surface unevenness is the degree of roughness of a surface.
Metal Removal Rate - (Measured in Cubic Meter per Second) - Metal removal rate (MRR) is the amount of material removed per time unit (usually per minute) when performing machining operations such as using a lathe or milling machine.

STEP 1: Convert Input(s) to Base Unit

Metal Removal Rate: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_sd = 1.11*(Z_w^0.384) --> 1.11*(10^0.384)

Evaluating ... ...

S_sd = 2.68734224187716

STEP 3: Convert Result to Output's Unit

2.68734224187716 Meter --> No Conversion Required

FINAL ANSWER

2.68734224187716 ≈ 2.687342 Meter <-- Surface Unevenness

What factors affects surface finish during EDM ?

The amount of material removed and the surface finish produced is dependent upon the current in the spark. The material removed by the spark can be assumed to be a crater. The amount removed therefore will depend upon the crater depth, which is directly proportional to the current. Thus as the material removed increases and at the same time the surface finish also decreases. However, decreasing the current in the spark, but increasing its frequency will improve the surface finish in view of the small crater size, but at the same time the material removal rate can be maintained by increasing the frequency.
