Step Turning of Mild Steel Rod (130 mm) with CNC Programming – Manual & G71 Cycle Explanation

 Introduction

In my experience teaching and working with lathes and CNC machines, step turning is one of the most important basic machining operations. I have used it many times while training students for practical exams and interviews.

In this example, I will explain step turning on a mild steel rod using a CNC lathe, along with two types of programming: manual (line-by-line) and the G71 roughing cycle. Both methods are important in industry, depending on job complexity and productivity.

Step turning is used to produce different diameters on a single rod. Here, the rod is reduced in size from 18 mm to 15 mm, 12 mm, 10 mm, and 8 mm, with each step 25 mm long.

I prefer this example because it clearly explains tool movement, dimensional control, and machining sequence, making it very useful for ITI, Diploma, and interview preparation.

Workpiece Details

Let me first explain the job clearly.

• Material: Mild Steel (MS)
• Total Length: 130 mm
• Original Diameter: 18 mm
• Machined Length: 100 mm
• Remaining (holding): 30 mm

Step Turning Details:

The rod is stepped into four equal sections, each of 25 mm length:

Step	Diameter (mm)	Length (mm)
Step 1	15 mm	25 mm
Step 2	12 mm	25 mm
Step 3	10 mm	25 mm
Step 4	8 mm	25 mm

So, the diameter is gradually reducing from 18 mm to 8 mm.

Machining Strategy

Before writing the program, we must think like a machinist.

• First → Facing
• Then → Rough turning
• Then → Step turning
• Finally → Finishing

We will first see manual programming, then optimise using the G71 cycle.

Explanation

1. Initialisation

• G21 → Metric units
• G18 → X-Z plane
• G40 →Cancel tool nose radius compensation
• G99 → Feed per revolution

This ensures the machine is in the correct mode.

2. Tool Selection

• T0101 → Tool 1 with offset 1
• G97 S1200 M03 → Spindle ON at 1200 RPM

3. Facing

We first make the front face flat:

G00 X20 Z2 
G01 Z0 

This defines the Z = 0 reference point.

4. Step Turning Concept

Now I explain the logic:

For each step:

• Move safely (G00)
• Reduce diameter (G01 X)
• Cut length (G01 Z)

Step 1

• Reduce from 18 → 15 mm
• Length = 25 mm

Step 2

• Reduce from 15 → 12 mm
• Next 25 mm

Step 3

• Reduce to 10 mm

Step 4

• Final diameter = 8 mm

5. Finishing Pass

We again trace a full profile with a small feed:

• Improves surface finish
• Removes tool marks
• Achieves accurate size

Limitation of Manual Programming

• Takes more time
• Not efficient for production
• Repetitive coding

That’s why we use the G71 cycle

Part 2: G71 Canned Cycle Program

Now I will explain the same job using the G71 roughing cycle, which is used in industries for automatic rough machining.

• P10 → Start block number
• Q40 → End block number
• U0.2 → Finishing allowance in X
• W0.1 → Finishing allowance in Z
• F → Feed rate

Profile Definition

Between N10 and N40, we define the final shape.

Important Rule:

• Only the final profile is written
• Machine automatically removes material layer by layer

Finishing Cycle

G70 P10 Q40;

• Removes remaining allowance
• Gives a smooth finish

Key Difference: Manual vs G71

Feature	Manual	G71
Programming	Long	Short
Efficiency	Low	High
Production	Not suitable	Best
Control	Full control	Semi-automatic

 Practical Tips (Very Important)

1. Why G96 (CSS: Constant Spindle Speed)?

• Maintains constant cutting speed
• Improves tool life

2. Why Finishing Allowance?

• Prevents rough surface
• Ensures final accuracy

3. Common Errors

• Wrong P and Q blocks
• Profile not continuous
• Wrong tool offset

Real Industry Insight

In industries:

• Manual programming → used for simple or trial jobs
• G71 cycle → used for mass production

90% of turning jobs use canned cycles

Conclusion

In this example, we have taken a 130 mm mild steel rod and performed step turning to achieve four different diameters: 15 mm, 12 mm, 10 mm, and 8 mm, each with a length of 25 mm.

I explained the complete machining using:

• Manual CNC programming (for understanding basics)
• G71 canned cycle (for industrial efficiency)

Note: “I strongly request that all the above programs be carefully checked and dry-run before execution to prevent tool damage or machine errors.”

 Frequently Asked Questions

1. What is step turning in machining?

Step turning is a lathe operation used to produce different diameters on a single workpiece, creating steps along its length.

2. Why is step turning important?

It is widely used to manufacture shafts, axles, and machine components where multiple diameters are required for assembly.

3. What material is commonly used for practice?

Mild Steel (MS) is commonly used because it is easy to machine, has a low cost, and is suitable for beginners.

4. What is the difference between manual programming and the G71 cycle?

• Manual programming → Step-by-step tool movement
• G71 cycle → Automatic roughing (faster and used in industry)

5. Can finishing be done without a G70 cycle?

Yes, finishing can be done manually using G01 with low feed and small depth of cut.

6. Why is facing done before step turning?

Facing ensures a flat reference surface (Z = 0) for accurate length measurement.

7. What happens if G21, G18, G99 are not given?

If already set, the program may run, but it is not safe. Always include them to avoid errors.

8. What is the use of G40 in CNC?

G40 cancels tool nose radius compensation, ensuring the tool moves in normal mode.

9. Why is X given a negative value during facing?

Giving X negative (like X-1) ensures the tool crosses the centre and removes any remaining material (pip).

10. What are common mistakes in step turning?

• Incorrect tool offset
• Wrong diameter input
• Not maintaining step lengths
• High feed causing poor finish

Plain Turning Using G71 Canned Cycle – My Practical Experience (Complete Guide)

 Introduction 

When I first started working with CNC lathes, I used to write manual turning programs for every step. If I had to reduce the diameter from 20 mm to 15 mm, I would write multiple G01 lines — pass by pass. It worked, but it was slow, confusing, and sometimes risky.

Later, I learned the G71 canned cycle, and honestly, it completely changed the way I program CNC machines. It saves time, reduces errors, and is perfect for real production work.

In this guide, I’ll explain the G71 canned cycle from real shop-floor experience, how it’s actually used in industry, along with common mistakes and practical solutions.

What is G71? (Simple Understanding) 

G71 is a rough turning cycle.

In simple words:

Instead of telling the machine “cut again and again,”
 You define the shape once, and G71 will automatically remove material in multiple passes.

This is very useful when:

• Material removal is high
• Diameter reduction is large
• Production is continuous

Why I Prefer G71 in Real Work

From my experience:

• Writing 10–15 lines manually is tiring
• One mistake = scrap part
• Time wasted during programming

With G71:

• Programming becomes simple
• The machine does roughing automatically
• Consistent cutting every time

G71 Syntax (What I Actually Remember)

I don’t try to memorise everything like a formula. I remember it like this:

G71 U(depth) R(retract)
G71 P(start) Q(end) U(finish X) W(finish Z) F(feed)

That’s enough to work confidently.

How I Understand Each Value (Practical Way)

• ·      U (depth of cut)

a.       How much material to remove per pass?

b.        I usually give 0.5 to 1 mm, depending on the material

• ·      R (retraction)

a.       Small movement back after each cut

b.       Prevents tool rubbing

•      P & Q

a.       These are block numbers where the profile starts and ends

b.       Many beginners make mistakes here

•      U & W (finishing allowance)

a.       Always leave small material (like 0.2 mm)

b.       Final finishing will be clean

Practical Example (Real Shop Situation)

Problem I Worked On:

• Raw diameter =  12 mm
• Final diameter = 10 mm
• Length = 90 mm

What Actually Happens in a Machine

From my observation:

• Tool starts from a safe position
• Cuts layer by layer (automatic passes)
• After each pass, it slightly retracts
• Leaves small material for finishing
• Finally, G70 gives smooth finish

This is exactly what we want in production.

Mistakes I Personally Faced (Very Important)

1. Tool Not Cutting

Once I gave the wrong X value (like X20 instead of X16 in diameter mode)

The machine moved but didn’t cut

Lesson:
Always check:

• Diameter mode
• Offset value

2. Wrong P and Q Blocks

I gave the wrong block numbers.

The machine didn’t follow the correct profile

Lesson:
Always double-check sequence numbers.

3. Too High Depth of Cut

I gave U = 2 mm in steel

Tool vibration + poor finish

a.       Lesson:

• Mild steel → 0.5 to 1 mm
• Hard material → even less

4. No Finishing Allowance

I forgot U and W in the second line

The final size was wrong

Lesson:
Always leave a small finishing stock.

My Practical Tips (From Real Work)

a.        Always start from a safe position (X > raw dia)

b.        Do a dry run first (very important)

c.        Use coolant properly

d.        Check the insert condition before running

e.        Don’t hurry — most errors happen due to tension

When I Use G71 (Real Decision)

I use G71 when:

• Diameter reduction is more
• Batch production is there
• Simple profile turning

I don’t use G71 when:

• Only a small finishing cut is needed
• Very complex contour

Why G70 is Important After G71

G71 only does rough cutting.

If you stop there:

• Surface will be rough
• Dimension may not be accurate

So I always use:

G70 P10 Q30

This gives the final finish and exact size

Real Advantage I Felt

After using G71 regularly:

• Programming time reduced
• Confidence increased
• Mistakes reduced
• Production became faster

This is why industries prefer canned cycles

FAQs (Based on Real Doubts)

1. Why is my tool not cutting in the G71 cycle?

Most common reasons:

• Wrong offset
• Wrong X value
• Tool above diameter

2. What is the correct depth of cut in G71?

It depends on the material:

• Aluminum → 1 to 2 mm
• Mild steel → 0.5 to 1 mm
• Hard material → 0.2 to 0.5 mm

Choosing the right depth improves tool life and surface finish.

3. Why is my G71 cycle taking too many passes?

If your U value (depth of cut) is too small, the machine will take more passes. Increase it slightly for faster machining, but stay within safe limits.

4. What happens if I don’t use G70 after G71?

G71 performs only roughing. Without G70:

• Surface finish will be poor
• Final dimensions may not be accurate

Always use G70 for finishing.

5. Can I use G71 for small diameter changes?

Yes, but it’s not efficient. For small cuts, manual G01 programming is faster and more suitable.

6. Why is my final dimension oversized after G71?

This happens when the finishing allowance (U and W) is not properly set. Always leave a small allowance (like 0.05 mm) and use G70 to achieve the final size.

7. What is the role of P and Q in G71?

P and Q define the start and end of the profile. If these block numbers are wrong, the machine will not follow the correct path.

8. Why does the tool retract after every pass in G71?

The R value controls retraction. This helps:

• Avoid tool rubbing
• Improve cutting efficiency
• Increase tool life

9. Can I use G00 inside G71 profile blocks?

No, it is not recommended. Always use G01 (cutting movement) inside profile blocks to ensure proper machining.

10. Why is my tool vibrating during G71 operation?

Common reasons:

• Too high depth of cut
• Worn-out tool insert
• Improper clamping
• Low spindle speed

Adjust cutting parameters and check tool condition.

Conclusion

If you are serious about CNC programming, G71 is a must-learn cycle. In real industry work, no one writes long manual programs for rough turning.

Once you understand G71 properly and practice it on different jobs, your programming speed and confidence will improve a lot.

 Final Advice

Don’t just read this.
