To calculate the minimum estimated machining time per pass, we need to consider the approach and over travel of the cutter.
Given data:
- Length of the block (L): 200 mm
- Diameter of the slab milling cutter (D): 34 mm
- Depth of cut (d): 2 mm
- Table feed (f): 18 mm/minute
Approach and Over Travel:
- Approach: It is the distance the cutter needs to travel to reach the starting point of the cut.
- Over Travel: It is the distance the cutter needs to travel after completing the cut.
Approach and over travel are equal in this case, so we can consider their combined distance as the minimum distance the cutter needs to travel per pass.
Calculating the minimum estimated machining time per pass:
1. Calculate the number of passes:
- The total depth of cut is given as 2 mm.
- Since the depth of cut per pass is also 2 mm, the number of passes required can be calculated as L/d.
Number of passes = L/d = 200 mm / 2 mm = 100 passes
2. Calculate the minimum distance the cutter needs to travel per pass:
- The total length of the block is given as 200 mm.
- The diameter of the cutter is given as 34 mm, so the effective length of the cut per pass is (L - D).
Effective length of cut per pass = L - D = 200 mm - 34 mm = 166 mm
3. Calculate the total machining distance:
- The total machining distance is the sum of the approach distance, the effective length of cut per pass, and the over travel distance.
Total machining distance = Approach + Effective length of cut per pass + Over travel
Total machining distance = (L - D) + (L - D) + (L - D) = 3(L - D)
4. Calculate the minimum estimated machining time per pass:
- The table feed is given as 18 mm/minute.
- Divide the total machining distance by the table feed to get the minimum estimated machining time per pass.
Minimum estimated machining time per pass = Total machining distance / Table feed
Minimum estimated machining time per pass = 3(L - D) / f = 3(200 mm - 34 mm) / 18 mm/minute ≈ 12 minutes
Therefore, the minimum estimated machining time per pass is approximately 12 minutes.
Given data:
- Length of the block (L): 200 mm
- Diameter of the slab milling cutter (D): 34 mm
- Depth of cut (d): 2 mm
- Table feed (f): 18 mm/minute
Approach and Over Travel:
- Approach: It is the distance the cutter needs to travel to reach the starting point of the cut.
- Over Travel: It is the distance the cutter needs to travel after completing the cut.
Approach and over travel are equal in this case, so we can consider their combined distance as the minimum distance the cutter needs to travel per pass.
Calculating the minimum estimated machining time per pass:
1. Calculate the number of passes:
- The total depth of cut is given as 2 mm.
- Since the depth of cut per pass is also 2 mm, the number of passes required can be calculated as L/d.
Number of passes = L/d = 200 mm / 2 mm = 100 passes
2. Calculate the minimum distance the cutter needs to travel per pass:
- The total length of the block is given as 200 mm.
- The diameter of the cutter is given as 34 mm, so the effective length of the cut per pass is (L - D).
Effective length of cut per pass = L - D = 200 mm - 34 mm = 166 mm
3. Calculate the total machining distance:
- The total machining distance is the sum of the approach distance, the effective length of cut per pass, and the over travel distance.
Total machining distance = Approach + Effective length of cut per pass + Over travel
Total machining distance = (L - D) + (L - D) + (L - D) = 3(L - D)
4. Calculate the minimum estimated machining time per pass:
- The table feed is given as 18 mm/minute.
- Divide the total machining distance by the table feed to get the minimum estimated machining time per pass.
Minimum estimated machining time per pass = Total machining distance / Table feed
Minimum estimated machining time per pass = 3(L - D) / f = 3(200 mm - 34 mm) / 18 mm/minute ≈ 12 minutes
Therefore, the minimum estimated machining time per pass is approximately 12 minutes.
