What is the main constraint (criteria) for selecting a cutting speed based on the two optimization criteria in machining economics?

Life of tool

Explanation:

The main criteria of selecting the cutting speed is the life of tool. We have to select the speed according to life of tool. Because, if we use high cutting speed and the tool does not able to withstand  that high speed ,due to this machining will lowered.

From the tool life equation

We can see that when velocity of cutting tool increase then life of tool decreases.

The other parameters for selecting the cutting speed

1. Feed

2. Depth of cut

3. Material

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
