Two different tools A and B having nose radius of 0.6 mm and 0.33 mm r...
Given:
- Nose radius of tool A (RA) = 0.6 mm
- Nose radius of tool B (RB) = 0.33 mm
- Feed rate for tool A (FA) = 0.2 mm/rev
- Feed rate for tool B (FB) = 0.1 mm/rev
To find:
- The tool that gives a better finish.
- The value of the ideal surface roughness.
Solution:
Step 1: Calculate the feed per tooth (ft) for each tool.
Feed per tooth is given by the formula:
ft = Feed rate (F) / Number of teeth (z)
For tool A:
ftA = FA / zA
For tool B:
ftB = FB / zB
Step 2: Calculate the material removal rate (MRR) for each tool.
Material removal rate is given by the formula:
MRR = ft x n x ap
Where:
n = Spindle speed (constant for both tools)
ap = Depth of cut (constant for both tools)
Step 3: Calculate the ideal surface roughness (Ra) for each tool.
The ideal surface roughness is given by the formula:
Ra = (RA + RB) / 2
Step 4: Compare the MRR and Ra values for both tools.
The tool that gives a better finish will have a lower value of MRR and Ra.
Calculations:
Given:
RA = 0.6 mm
RB = 0.33 mm
FA = 0.2 mm/rev
FB = 0.1 mm/rev
Assuming the number of teeth (z) is the same for both tools.
Step 1: Calculate the feed per tooth (ft) for each tool.
ftA = FA / zA
ftB = FB / zB
Step 2: Calculate the material removal rate (MRR) for each tool.
As the spindle speed (n) and depth of cut (ap) are constant for both tools, the MRR will be directly proportional to the feed per tooth (ft).
Therefore, we can say that MRRA = 2 x MRRB
(MRRA is the MRR for tool A and MRRB is the MRR for tool B)
Step 3
- Nose radius of tool A (RA) = 0.6 mm
- Nose radius of tool B (RB) = 0.33 mm
- Feed rate for tool A (FA) = 0.2 mm/rev
- Feed rate for tool B (FB) = 0.1 mm/rev
To find:
- The tool that gives a better finish.
- The value of the ideal surface roughness.
Solution:
Step 1: Calculate the feed per tooth (ft) for each tool.
Feed per tooth is given by the formula:
ft = Feed rate (F) / Number of teeth (z)
For tool A:
ftA = FA / zA
For tool B:
ftB = FB / zB
Step 2: Calculate the material removal rate (MRR) for each tool.
Material removal rate is given by the formula:
MRR = ft x n x ap
Where:
n = Spindle speed (constant for both tools)
ap = Depth of cut (constant for both tools)
Step 3: Calculate the ideal surface roughness (Ra) for each tool.
The ideal surface roughness is given by the formula:
Ra = (RA + RB) / 2
Step 4: Compare the MRR and Ra values for both tools.
The tool that gives a better finish will have a lower value of MRR and Ra.
Calculations:
Given:
RA = 0.6 mm
RB = 0.33 mm
FA = 0.2 mm/rev
FB = 0.1 mm/rev
Assuming the number of teeth (z) is the same for both tools.
Step 1: Calculate the feed per tooth (ft) for each tool.
ftA = FA / zA
ftB = FB / zB
Step 2: Calculate the material removal rate (MRR) for each tool.
As the spindle speed (n) and depth of cut (ap) are constant for both tools, the MRR will be directly proportional to the feed per tooth (ft).
Therefore, we can say that MRRA = 2 x MRRB
(MRRA is the MRR for tool A and MRRB is the MRR for tool B)
