💡 Hint

Common Mistakes

Choosing 'pocket' which is a different roughing method.

Selecting 'finishing' which is for final passes.

The adaptive roughing strategy is selected by setting strategy to 'adaptive'.

Complete the code to define the pocket roughing area.

CNC Programming

pocket_area = [1]

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

💡 Hint

Common Mistakes

Using a single number instead of coordinates.

Using strategy names instead of area coordinates.

The pocket area is defined by a list of corner points forming a square.

3fill in blank

hard

Fix the error in the code to set the step-over for adaptive roughing.

CNC Programming

step_over = [1] * tool_diameter

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

A0.5

Bstep_over

Cfeed_rate

Dtool_diameter

💡 Hint

Common Mistakes

Using tool_diameter twice causing incorrect calculation.

Using feed_rate which is unrelated to step-over.

Step-over is a fraction (like 0.5) of the tool diameter to control material removal.

4fill in blank

hard

Fill both blanks to create a dictionary for pocket roughing parameters.

CNC Programming

pocket_params = {'area': [1], 'step_over': [2]

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

A[(0,0), (40,0), (40,40), (0,40)]

B0.4

C0.5

💡 Hint

Common Mistakes

Using strategy names instead of area coordinates.

Using step-over values greater than 1.

The 'area' is a list of coordinates and 'step_over' is a decimal fraction.

5fill in blank

hard

Fill all three blanks to define an adaptive roughing toolpath with feed rate and step-down.

CNC Programming

adaptive_toolpath = {'strategy': [1], 'feed_rate': [2], 'step_down': [3]

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

💡 Hint

Common Mistakes

Using 'pocket' instead of 'adaptive' for strategy.

Confusing feed rate with step-down values.

The strategy is 'adaptive', feed rate is 1500 mm/min, and step-down is 2.5 mm.
