Toolpath generation concept in CNC Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the toolpath with the correct command.

CNC Programming

G[1] ; Start of toolpath

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

💡 Hint

Common Mistakes

Using G00 which is rapid move and does not generate a cutting path.

The command G01 is used to start a linear interpolation move, which is the basic movement for toolpath generation.

medium

Complete the code to move the tool to X=10, Y=5 in a straight line.

CNC Programming

G01 X[1] Y5

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

C15

D10

💡 Hint

Common Mistakes

Using wrong X coordinate value.

The tool moves to X=10, Y=5 using the command G01 X10 Y5 which is a linear move to those coordinates.

3fill in blank

hard

Fix the error in the code to correctly set the feed rate to 150.

CNC Programming

F[1] ; Set feed rate

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

A150

B0150

C015

D15

💡 Hint

Common Mistakes

Adding leading zeros which may cause errors.

The feed rate should be set as F150 without leading zeros for correct interpretation.

4fill in blank

hard

Fill both blanks to create a toolpath dictionary with coordinates and feed rate condition.

CNC Programming

toolpath = [1]: (x, y), 'feed' [2] 100

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

A'position'

B>

C<

D'speed'

💡 Hint

Common Mistakes

Using wrong dictionary keys or incorrect comparison operators.

The dictionary key should be 'position' for coordinates, and the feed rate condition should be greater than 100 using >.

5fill in blank

hard

Fill all three blanks to generate a filtered toolpath dictionary with X coordinate, feed rate, and condition.

CNC Programming

filtered_path = [1]: coords for coords in path if coords['X'] [2] 50 and coords['feed'] [3] 120}

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

A'X'

B>

C<

D'feed'

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up keys or comparison operators.

The dictionary uses 'X' as key, checks if X is greater than 50, and feed rate key is 'feed' with condition less than 120.
