The process starts machining one side of the part, then the part is flipped to machine the other side in a second setup.

Execution Sample

CNC Programming

O1000 (Program Start)
(T1 - Face Mill)
G00 X0 Y0 Z5
G01 Z-5 F100
(Complete Side A)
M30

This sample shows the first setup machining side A of the part.

Execution Table

Step	Action	Setup	Machine Side	Tool Position	Operation Status
1	Load Part	Setup 1	Side A	Home	Ready
2	Start Machining	Setup 1	Side A	X0 Y0 Z5	In Progress
3	Cut to Depth	Setup 1	Side A	X0 Y0 Z-5	In Progress
4	Complete Side A Machining	Setup 1	Side A	X0 Y0 Z-5	Done
5	Remove Part	Between Setups	N/A	N/A	Done
6	Flip Part	Between Setups	N/A	N/A	Done
7	Load Part	Setup 2	Side B	Home	Ready
8	Start Machining	Setup 2	Side B	X0 Y0 Z5	In Progress
9	Cut to Depth	Setup 2	Side B	X0 Y0 Z-5	In Progress
10	Complete Side B Machining	Setup 2	Side B	X0 Y0 Z-5	Done
11	Remove Finished Part	Setup 2	Side B	N/A	Done

💡 All machining operations on both sides completed, part finished.

Key Moments - 3 Insights

Why do we need to flip the part between setups?

Flipping the part allows machining the opposite side, as shown in execution_table steps 5 and 6 where the part is removed and flipped before Setup 2.

What happens if the part is not properly aligned after flipping?

Improper alignment can cause machining errors on Side B, because the tool positions assume correct orientation as shown in steps 7 to 10.

Why is the tool position reset to Home after flipping?

Resetting to Home ensures safe starting position and correct coordinates for the new side, as seen in steps 7 and 8.

Visual Quiz - 3 Questions

Look at the execution_table, at which step does the part get flipped?

A Step 7

B Step 5

C Step 6

D Step 4

💡 Hint

Check the 'Action' column for 'Flip Part' in the execution_table.

According to variable_tracker, what is the 'Machining Status' after Setup 1?

A Side A Done

B Flipped

C Not Started

D Side B Done

💡 Hint

Look at the 'Machining Status' row under 'After Setup 1' in variable_tracker.

If the tool position did not reset to Home after flipping, which step in execution_table would be affected?

A Step 3

B Step 7

C Step 10

D Step 1

💡 Hint

Refer to the 'Tool Position' changes in variable_tracker and the 'Start Machining' action in execution_table.

Concept Snapshot

Multiple setups with flip operations:
- Machine Side A in Setup 1
- Remove and flip part
- Machine Side B in Setup 2
- Reset tool to Home after flipping
- Ensures complete machining on both sides

Full Transcript

This visual execution shows the process of multiple setups with flip operations in CNC programming. The part is first loaded and machined on Side A during Setup 1. After completing Side A, the part is removed and flipped to expose Side B. Setup 2 then machines Side B. The tool position resets to Home after flipping to ensure correct coordinates. Variables like part position, tool position, and machining status update step-by-step. Key moments include the importance of flipping, alignment, and tool reset. The execution table traces each step from loading to finished part removal.
