Toolpath simulation and verification in CNC Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the toolpath simulation.

CNC Programming

start_simulation([1])

Drag options to blanks, or click blank then click option'

Atoolpath_data

Bsimulation_speed

Cerror_log

Dmachine_state

Attempts:

3 left

💡 Hint

Common Mistakes

Passing simulation speed instead of toolpath data.

Using machine state which is not the input for simulation start.

The simulation starts by passing the toolpath data to the start_simulation function.

2fill in blank

medium

Complete the code to check if the simulation detected any collisions.

CNC Programming

if simulation_result.[1]():

Drag options to blanks, or click blank then click option'

Adetect_collision

Bhas_errors

Ccheck_collision

Dcollision_detected

Attempts:

3 left

💡 Hint

Common Mistakes

Using has_errors which checks for general errors, not collisions.

Using detect_collision which is not a method of simulation_result.

The method collision_detected() returns True if any collision was found during simulation.

3fill in blank

hard

Fix the error in the code to correctly retrieve the simulation time.

CNC Programming

total_time = simulation.[1]

Drag options to blanks, or click blank then click option'

Atotal_time()

Bget_total_time()

Csimulation_time

DgetTime()

Attempts:

💡 Hint

Common Mistakes

Using total_time() which is not defined.

Accessing simulation_time attribute which may not exist.

The method get_total_time() correctly returns the total simulation time as a value.

4fill in blank

hard

Fill both blanks to filter and store only safe toolpath points.

CNC Programming

safe_points = [point for point in toolpath if point.[1]() and not point.[2]()]

Drag options to blanks, or click blank then click option'

Ais_within_bounds

Bis_collision_point

Cis_valid

Dis_error

Attempts:

3 left

💡 Hint

Common Mistakes

Using is_valid which may not check bounds.

Using is_error which is too general.

We keep points that are within bounds and exclude those that are collision points.

5fill in blank

hard

Fill all three blanks to create a dictionary of points with their status if safe.

CNC Programming

point_status = [1]: [2] for [3] in toolpath if [3].is_within_bounds()}}

Drag options to blanks, or click blank then click option'

Ap.id

Bp.status

Cpoint

Dp

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'point' as loop variable but not matching keys and values.

Using point object as key which is not hashable.

We use p.id as key, p.status as value, and 'p' as the loop variable name.
