Rest machining for remaining material in CNC Programming - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start rest machining with the correct tool call.

CNC Programming

T[1] M06 ; Tool change command

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

B04

C03

D02

💡 Hint

Common Mistakes

Using the wrong tool number for rest machining.

Forgetting the M06 command after the tool number.

Tool 02 is commonly used for rest machining to remove remaining material after roughing.

2fill in blank

medium

Complete the code to set the spindle speed for rest machining.

CNC Programming

S[1] M03 ; Set spindle speed and start spindle clockwise

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

B1500

C4500

D6000

💡 Hint

Common Mistakes

Setting spindle speed too high or too low for the tool and material.

Omitting the M03 command to start the spindle.

A spindle speed of 3000 RPM is typical for rest machining to balance speed and finish quality.

3fill in blank

hard

Fix the error in the rest machining feed rate command.

CNC Programming

F[1] ; Set feed rate for rest machining

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

A200

B100

C300

D400

Attempts:

💡 Hint

Common Mistakes

Using feed rates that are too high causing tool breakage.

Using feed rates that are too low causing inefficient machining.

A feed rate of 200 mm/min is appropriate for rest machining to ensure smooth cutting without tool overload.

4fill in blank

hard

Fill both blanks to complete the rest machining loop and tool path command.

CNC Programming

G[1] X[2] Y50 ; Rest machining linear move

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

A01

B00

C100

D150

Attempts:

3 left

💡 Hint

Common Mistakes

Using G01 for rapid moves which slows the program.

Using invalid coordinate values.

G00 is the rapid positioning command, and X100 moves the tool to X=100 for rest machining.

5fill in blank

hard

Fill all three blanks to complete the rest machining conditional check and loop.

CNC Programming

IF [#[1] [2] [3]] GOTO 100

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

A500

C0

D<

💡 Hint

Common Mistakes

Using incorrect variable numbers.

Using wrong comparison operators.

Omitting the GOTO command.

The condition checks if variable #500 is greater than 0 to continue rest machining by jumping to line 100.
