What Are The Real Cost Savings With 5 Axis CNC Machining?

5 axis CNC is not necessarily expensive. This is due to the fact that the total expense lowered through process improvement is considerable in small to medium-series production.

A Revolution in Single-Setup: Reducing Fixture and Labor Costs

It is possible for 5 axis CNC machining services to perform multifaceted machining in one setup because it slashes dedicated fixture design and manufacturing cost by more than 60%, which is the case when using three-axis machining systems. On the other hand, manual operation time and machine downtime are cut by 40%.

Economies of Scale: The Cost Cliff of a Single Unit in Mass Production

The following is a cost comparison of machining 100 complex aluminum parts (including 3 undercut surfaces and 2 complex curved surfaces):

Cost Breakdown	5 axis CNC machining	3-Axis Machining	Cost Difference Rate
Material Cost (USD)	1200	1200	0%
Jig Cost (USD)	800	2000	-60%
Labor Cost (USD)	3000	5000	-40%
Rework Cost (USD)	150	600	-75%
Total Cost per Unit (USD)	51.5	88	-41.5%

Precision Equals Profit: Reducing Rework and Material Waste

The repeatability is very high (e.g., ±0.003mm) for 5 axis CNC machining services. The statistics available at JS Precision indicate that there has been a considerable reduction in material wastage and rework rate after adopting five axis machining.

Figure 1 Unlike three-axis machining centers that require repeated repositioning, five axis machining centers eliminate these steps, saving labor costs and reducing the possibility of errors.

What Are The Untold Limitations Of 5 Axis CNC Machining Complex Surfaces?

Knowledge about 5 axis machining centers limitations is a prerequisite for efficient production. Preventing such difficulties in advance can eliminate delays in projects.

The Achilles Heel of Tool Vibration

While machining deep cavities or overhanging features, lack of tool rigidity may cause vibrations resulting in the Ra value increasing from 0.4 to above 1.2μm. JS Precision customarily minimizes this risk of vibration by an average of 80% either by reducing the tool overhang or employing damping tool holders.

Balancing Efficiency, Quality with Ball End Mills

For finishing with ball end mills, low surface finish with Ra of 0.4μm has been achieved using small step over distances that increase exponentially with time. This has been addressed using a high-speed milling cutter strategy or barrel tools with more than 30% increased efficiency.

Internal Challenges of Cooling and Chip Removal

During machining of complex channels in fluid flow systems, a deficiency in coolant reaching the machining area might result in tool overheating. The 5 axis machining centers manufactured by JS Precision feature a spindle center internal cooling system of more than 70 bar along with path programming for optimized removal of chips.

Figure 2 Complex surface machining is a major challenge in the field of CNC machining.

Why Does Your Design Irrevocably Require 5 Axis Over 3+2?

Where components require complex surfaces or dynamic accuracy, 5 axis CNC machining service can only support the process, and it differs entirely from 3+2 indexing machining.

When 3-Axis Machining Encounters Geometric Bottlenecks

For example, using an automotive headlight cover mold as a case study, the undercut surface prevents the 3-axis machine tool from reaching the machining region. Custom 5 axis CNC machining allows adjusting the machining direction freely. Thus, the machining is done in a single pass without grinding by hand.

3+2 Indexing vs. True 5-Axis Linkage: Fundamental Differences

Comparison Dimensions	3+2 Indexing Machining	True 5-Axis Linkage Machining
Motion Mode	Fixed Angle Post-Inclination 3-Axis Milling	Continuous Tool Direction Adjustment
Applicable Parts	Simple Polyhedral Features	Continuous Complex Curved Surface Parts
Surface Finish	Ra 1.0-1.6μm	Ra 0.4-0.8μm
Machining Efficiency	Medium	High (Reduces Path Overlap)
Typical Applications	Box-Type Parts	Impellers and Turbine Blades

Case Study Insights: The Victory of Integrated Manufacturing

In aerospace applications, the introduction of 5 axis machining centers has allowed for integrated machining of turbine blades, thereby reducing several component welding steps to only one, enhancing strength by 40%, and adopting aerodynamics by 15%, which could not have been achieved through 3+2 machining.

Figure 3 The main difference between five axis linkage machining and three-axis+two axis machining lies in the usage of each axis during the machining process.

Step 2: Five-Axis Process Planning and Simulation:

The five-axis linkage tool path was planned, verified in Vericut simulation, avoided three possible tool interferences, and the spindle speed and feed rate were set to 8500 rpm and 3800 mm/min, respectively.

Step 3: High-Precision Five-Axis Execution and In-Machine Inspection:

We employed a five-axis machine tool, namely, the DMG MORI DMU 50, which was coupled with a vacuum fixture, facilitating one-time clamping and machining. Tolerances regarding key hole diameters were maintained within ±0.013 mm, and geometric tolerances within ≤ 0.02 mm, thus decreasing the machining cycle to 5 days per set.

Results: Triple Breakthroughs in Performance, Weight, and Cost

• The weight of the finished bracket has decreased from 1.2 kilograms to 0.9 kilograms (a 25% reduction in weight).
• The utilization rate of raw materials has increased from 66.7% to 69.2%.
• The manufacturing cost has been reduced to $2080 per set (a 35% decrease).
• The vibration fatigue life has been increased from 800 hours to over 8500 hours (a tenfold increase).
