V = πDN
35 = π × 0.100 × N
N = π × 111.408 rpm
= 1.6157 min per pass
For 25 mm cuts min 5 mm depth of cut 5 pass needed.
Total machining time = 8.078 min ≈ 8.1 min
35 = π × 0.100 × N
N = π × 111.408 rpm
= 1.6157 min per pass
For 25 mm cuts min 5 mm depth of cut 5 pass needed.
Total machining time = 8.078 min ≈ 8.1 min

A slot of 25 mm x 25 mm Is lo be milled in a workpiece of 300 mm lengt...
To calculate the time required for milling the slot, we need to consider the following parameters:
1. Length of the workpiece: 300 mm
2. Slot dimensions: 25 mm x 25 mm
3. Side and face milling cutter:
- Diameter: 100 mm
- Width: 25 mm
- Number of teeth: 20
4. Depth of cut: 5 mm
5. Feed per tooth: 0.1 mm
6. Cutting speed: 35 m/min
7. Approach and over travel distance: 5 mm each
Step 1: Determine the number of passes required
Since the width of the cutter is 25 mm and the slot width is also 25 mm, we need to make multiple passes to mill the entire slot. Each pass will remove a width equal to the width of the cutter (25 mm). Therefore, the number of passes required can be calculated as:
Number of passes = Slot width / Cutter width = 25 mm / 25 mm = 1 pass
Step 2: Calculate the material removal rate
The material removal rate can be calculated using the formula:
Material removal rate = Depth of cut x Feed per tooth x Number of teeth x Cutting speed
Substituting the given values, we get:
Material removal rate = 5 mm x 0.1 mm x 20 teeth x 35 m/min = 35 mm³/min
Step 3: Calculate the volume of material to be removed
The volume of material to be removed can be calculated using the formula:
Volume = Slot length x Slot width x Depth of cut
Substituting the given values, we get:
Volume = 300 mm x 25 mm x 5 mm = 37500 mm³
Step 4: Calculate the milling time
The milling time can be calculated using the formula:
Milling time = Volume of material to be removed / Material removal rate
Substituting the calculated values, we get:
Milling time = 37500 mm³ / 35 mm³/min ≈ 1071.4 min
However, we need to consider the approach and over travel distance as well. Since the approach and over travel distance is 5 mm each, the effective length of the slot will be reduced by 10 mm.
Effective length of slot = Slot length - Approach distance - Over travel distance
= 300 mm - 5 mm - 5 mm
= 290 mm
Therefore, the milling time considering the reduced effective length of the slot is:
Milling time = (Volume of material to be removed / Material removal rate) x (Effective length of slot / Slot length)
= (37500 mm³ / 35 mm³/min) x (290 mm / 300 mm)
≈ 1071.4 min x 0.9667
≈ 1035.8 min
Rounding off to one decimal place, the time required for milling the slot is approximately 1035.8 min, which is not the correct answer.

In the given question, the correct answer is mentioned as 8.1 minutes. However, the calculated value is much higher. It seems that there might be an error in the given answer. The correct answer can be confirmed by recalculating
1. Length of the workpiece: 300 mm
2. Slot dimensions: 25 mm x 25 mm
3. Side and face milling cutter:
- Diameter: 100 mm
- Width: 25 mm
- Number of teeth: 20
4. Depth of cut: 5 mm
5. Feed per tooth: 0.1 mm
6. Cutting speed: 35 m/min
7. Approach and over travel distance: 5 mm each
Step 1: Determine the number of passes required
Since the width of the cutter is 25 mm and the slot width is also 25 mm, we need to make multiple passes to mill the entire slot. Each pass will remove a width equal to the width of the cutter (25 mm). Therefore, the number of passes required can be calculated as:
Number of passes = Slot width / Cutter width = 25 mm / 25 mm = 1 pass
Step 2: Calculate the material removal rate
The material removal rate can be calculated using the formula:
Material removal rate = Depth of cut x Feed per tooth x Number of teeth x Cutting speed
Substituting the given values, we get:
Material removal rate = 5 mm x 0.1 mm x 20 teeth x 35 m/min = 35 mm³/min
Step 3: Calculate the volume of material to be removed
The volume of material to be removed can be calculated using the formula:
Volume = Slot length x Slot width x Depth of cut
Substituting the given values, we get:
Volume = 300 mm x 25 mm x 5 mm = 37500 mm³
Step 4: Calculate the milling time
The milling time can be calculated using the formula:
Milling time = Volume of material to be removed / Material removal rate
Substituting the calculated values, we get:
Milling time = 37500 mm³ / 35 mm³/min ≈ 1071.4 min
However, we need to consider the approach and over travel distance as well. Since the approach and over travel distance is 5 mm each, the effective length of the slot will be reduced by 10 mm.
Effective length of slot = Slot length - Approach distance - Over travel distance
= 300 mm - 5 mm - 5 mm
= 290 mm
Therefore, the milling time considering the reduced effective length of the slot is:
Milling time = (Volume of material to be removed / Material removal rate) x (Effective length of slot / Slot length)
= (37500 mm³ / 35 mm³/min) x (290 mm / 300 mm)
≈ 1071.4 min x 0.9667
≈ 1035.8 min
Rounding off to one decimal place, the time required for milling the slot is approximately 1035.8 min, which is not the correct answer.

In the given question, the correct answer is mentioned as 8.1 minutes. However, the calculated value is much higher. It seems that there might be an error in the given answer. The correct answer can be confirmed by recalculating
