Calculation of Machining Time for Facing Operation on a CNC Lathe
Given Data:
- Outer diameter of the disc (Do) = 200 mm
- Inner diameter of the disc (Di) = 0 mm (assumed as zero)
- Depth of cut (d) = 1 mm
- Cutting speed (V) = 90 m/min
- Main cutting force (F) = 200 N
Approach:
- The machining time for a facing operation can be calculated using the formula:
Machining Time = (Volume of material to be removed) / (Material removal rate)
Calculation Steps:
1. Calculation of Volume of Material to be Removed:
- The volume of material to be removed can be calculated by subtracting the volume of the inner disc from the volume of the outer disc.
- Volume of outer disc = π * (Do)2 * d / 4
- Volume of inner disc = π * (Di)2 * d / 4
- Volume of material to be removed = Volume of outer disc - Volume of inner disc
2. Calculation of Material Removal Rate:
- Material removal rate can be calculated by multiplying the cutting speed with the feed per revolution.
- Material Removal Rate = Cutting speed * Feed per revolution
3. Calculation of Machining Time:
- Machining Time = Volume of material to be removed / Material Removal Rate
Calculation:
1. Calculation of Volume of Material to be Removed:
- Volume of outer disc = π * (200 mm)2 * 1 mm / 4 = 31416 mm3
- Volume of inner disc = π * (0 mm)2 * 1 mm / 4 = 0 mm3
- Volume of material to be removed = 31416 mm3 - 0 mm3 = 31416 mm3
2. Calculation of Material Removal Rate:
- Material Removal Rate = 90 m/min * 0.1 mm/rev = 9 mm3/min
3. Calculation of Machining Time:
- Machining Time = 31416 mm3 / 9 mm3/min = 3489.56 min
Answer:
The machining time for the facing operation on the CNC lathe is approximately 3489.56 minutes.
Given Data:
- Outer diameter of the disc (Do) = 200 mm
- Inner diameter of the disc (Di) = 0 mm (assumed as zero)
- Depth of cut (d) = 1 mm
- Cutting speed (V) = 90 m/min
- Main cutting force (F) = 200 N
Approach:
- The machining time for a facing operation can be calculated using the formula:
Machining Time = (Volume of material to be removed) / (Material removal rate)
Calculation Steps:
1. Calculation of Volume of Material to be Removed:
- The volume of material to be removed can be calculated by subtracting the volume of the inner disc from the volume of the outer disc.
- Volume of outer disc = π * (Do)2 * d / 4
- Volume of inner disc = π * (Di)2 * d / 4
- Volume of material to be removed = Volume of outer disc - Volume of inner disc
2. Calculation of Material Removal Rate:
- Material removal rate can be calculated by multiplying the cutting speed with the feed per revolution.
- Material Removal Rate = Cutting speed * Feed per revolution
3. Calculation of Machining Time:
- Machining Time = Volume of material to be removed / Material Removal Rate
Calculation:
1. Calculation of Volume of Material to be Removed:
- Volume of outer disc = π * (200 mm)2 * 1 mm / 4 = 31416 mm3
- Volume of inner disc = π * (0 mm)2 * 1 mm / 4 = 0 mm3
- Volume of material to be removed = 31416 mm3 - 0 mm3 = 31416 mm3
2. Calculation of Material Removal Rate:
- Material Removal Rate = 90 m/min * 0.1 mm/rev = 9 mm3/min
3. Calculation of Machining Time:
- Machining Time = 31416 mm3 / 9 mm3/min = 3489.56 min
Answer:
The machining time for the facing operation on the CNC lathe is approximately 3489.56 minutes.
