Complete the code to select the correct machining strategy for a smooth surface finish.
strategy = '[1]' # Choose the best strategy for fine surface finish
The finishing strategy is used to achieve a smooth surface finish by removing small amounts of material precisely.
Complete the code to set the cycle time based on the selected strategy.
if strategy == 'finishing': cycle_time = [1] # Time in minutes for finishing
Finishing usually takes less time than roughing because it removes less material.
Fix the error in the code that calculates surface finish quality based on strategy.
if strategy == 'roughing': surface_finish = [1] # Higher value means rougher finish
Roughing leaves a rough surface, so the surface finish value is higher (worse).
Fill both blanks to calculate total machining time and select the strategy.
total_time = base_time [1] strategy_time strategy = '[2]'
Total machining time is the sum of base time and strategy time. The finishing strategy is chosen for better surface finish.
Fill all three blanks to create a dictionary mapping strategies to their cycle times and select the best strategy.
cycle_times = {'roughing': [1], 'finishing': [2], 'drilling': [3]
best_strategy = min(cycle_times, key=cycle_times.get)Roughing takes 60 minutes, finishing 10, and drilling 5. The best strategy by shortest cycle time is drilling.
