What Exactly Are 5 Axis CNC Machining Services?

5 axis CNC machining is an all-round manufacturing service which combines very accurate, very free, and very efficient features.

In contrast to three axis machining, which restricts movement to the X, Y, and Z linear axes only, this 5 axis CNC machining exploits the addition of two rotary axes (usually the A and C axes) to the three linear axes. Thus, the tool can be positioned at an almost unlimited number of angles to the workpiece.

Its two main uses are very specific:

• Precision tooling, e.g. injection mold cores and die-casting mold inserts, which entail complex surfaces and require high precision.
• The manufacture of very complicated parts, e.g. impellers, medical skeletons, and optical components, that are hard to be processed in traditional ways.

5 axis machining service is more than a mere machining technique, it is a full package solution that covers design optimization, programming, machining, and inspection.

How Does a 5 Axis Machining Center Work?

Coordination of Motion Axes: The Dance of X, Y, Z, A, C

A 5 axis machining center consists of three linear axes (X, Y, Z) and two rotary axes (A, C). A, axis is a rotation around the X-axis, and C- axis is a rotation around the Z-axis. The coordinated movement of these axes enables the tool to have any position and angle on the workpiece.

Normally, three axis machining needs the workpiece to be repositioned several times, but 5 axis machining can do the machining of multiple surfaces of a part with just one setting. This is the main benefit of 5 axis CNC machining.

Core Brain: High, End CNC Control Systems

High-end CNC control systems like Siemens SINUMERIK ONE and Heidenhain TNC 640 are the core of 5 axis machining centers. These control systems use sophisticated five axis linkage interpolation algorithms to convert the CAD model into a smooth, precise tool path. They also carry out real, time collision detection to avoid tool and machine damage during machining.

Structural Forms: Dual Rotary Table vs. Rotary Table with Swiveling Head

5 axis vertical machining center is usually of two main structural types:

• Dual Rotary Table: The two rotary axes are on the worktable side. This is a right choice for small many-sided parts. The workspace is less, but the machining accuracy is higher.
• Rotary Table with Swiveling Head: One rotary axis is on the worktable, and the other is on the spindle head. It is a good solution for big deep-cavity parts. The machining range is larger, however, more spindle rigidity is required.

How To Choose a High-Performance 5 Axis Vertical Machining Center?

Precision Foundation: Positioning Accuracy and Repeatability

Two main criteria used to evaluate the accuracy of a 5 axis vertical machining center are:

• Positioning accuracy: It measures how far the tool's actual location is from its theoretical one. Top-tier machine tools can usually attain 0.003mm.
• Repeatability: It refers to the error when the tool is placed in the same spot multiple times. Usually 0.0015mm.

These two performance parameters lead to the dimensional accuracy and surface finishing of the products.

Stability Guarantee: Machine Tool Rigidity, Thermal Stability, and Dynamic Performance

• Machine Tool Rigidity: The mineral casting bed efficiently dampens the vibration, thus improving the stability during the machining process.
• Thermal Stability: Spindle thermal expansion compensation technology helps maintain machining accuracy by reducing the effect of temperature variations.
• Dynamic Performance: With the help of linear motors and roller guides, high-speed motion is achieved, thus, the maximum spindle speeds can be 30, 000 rpm, which is a perfect cutting speed for aluminum alloys.

High-Efficiency Production Support: Tooling and Tool Magazine System

• Tool Magazine Capacity: A tool magazine with over 60 tools can fulfill the needs of manufacturing complex components and thus significantly decrease the time required for tool change.
• Tool Change Speed: Automatic Tool Changer (ATC) time is less than 2 seconds, hence the production efficiency is increased.
• Specialized Tools: Long, neck tools designed especially for 5 axis machining and dynamic balancing technology are used for deep cavity machining so that tool interference can be avoided.

Which Problems Can 5 Axis Milling Services Solve That 3-Axis Cannot?

Problem 1: High Surface Smoothness Machining of Complex Surfaces

If you look at a turbine blade and propeller, 5 axis milling services can hold the tool precisely perpendicular to the surface throughout the entire machining process, thus, it is not the "step effect" in 3 axis machining, and it got a high surface finish (Ra 0.2, 0.8 m). The complex parts 5-axis machining of this type of component can only be efficiently achieved through 5-axis linkage.

Problem 2: Deep Cavities, Undercuts, and Inaccessible Features

In the case of molds with angled ejectors and medical implants with undercut structures, three axis machining is not able to reach the machining areas due to the limited accessibility. 5 axis milling services can change the tool angle through the rotary axis to machine the sidewalls, bottoms, and negative angle areas, thus, the design freedom of parts is greatly expanded.

Problem 3: Single, Set "Complete Machining" of Polyhedral Parts

For example, engine cylinder heads have features in five different directions. In this case, three axis machining needs five setups, which will take several hours. 5 axis milling services can finish all the machining in a single setup, thus, the setup time is reduced to a few minutes and the errors caused by multiple setups are eliminated.

Machining Part Type	5-Axis Milling Services Machining Error (mm)	3-Axis Machining Error (mm)	Single-Piece Machining Time (min)	Daily Capacity (pieces)	Single-Piece Machining Cost (USD)
Turbine Blade	±0.002	±0.015	45	12	185
Engine Cylinder Head	±0.003	±0.020	80	8	290
Medical Implant	±0.001	±0.010	35	15	220
Optical Component Support	±0.0008	±0.008	30	18	160
Mold Angled Ejector	±0.0025	±0.012	50	10	145

How To Optimize Design For Cost-Effective Complex Parts 5-Axis Machining?

Design Golden Rules: Avoiding Tool Interference and Limiting Parameters

• The radius of the inner corner must be at least 1/3 of the tool diameter, the use of ultra small tools should be avoided.
• The depth-to-width ratio should not be greater than 8:1 to minimize tool vibration and deflection.
• Features that necessitate excessively long or thin tools to access should be avoided, this results in shorter machining time, less tool wear, and compliance with ASME B5.54-2011 standards.

Material and Process Synergy: From Titanium Alloys to PEEK

Material Type	Cutting Speed ​​(RPM)	Tool Wear Rate	Cooling Requirements	Applicable Scenarios
Applicable Scenarios	30000	Low	Air Cooling	Aerospace Structural Components
Stainless Steel 316L	15000	Medium	Emulsion Cooling	Medical Devices
Titanium Alloy Ti6Al4V	12000	High	High Pressure Cooling	Engine Parts
PEEK	10000	Medium	Air Cooling	Medical Implants

Different materials have different cutting characteristics. Selecting appropriate process parameters can improve machining efficiency and reduce costs.

The Value of Pre-Simulation: Avoiding Real, World Mistakes through Virtual Machining

In the CAM programming stage, it is necessary to use software such as VERICUT for comprehensive tool path simulation and collision detection, which can prevent machine tool collision losses worth tens of thousands of dollars and optimize machining time. For complex parts 5-axis machining, simulation can reduce the trial cutting time by more than 50%.

Case Study: Aerospace Titanium Alloy Engine Bracket, Reduced From 18 Hours To 5 Hours, Reducing Weight By 35%

Challenge: Manufacturing Dilemmas of Topology-Optimized Components

A customer had designed a topology, derived titanium alloy (Ti6Al4V) engine mount. The shape was very complex, like organic mesh topology with curved surface and uneven wall thickness (the thinnest part is only 1.2mm).

Multi-part welding of traditional way had been heavy and weak in strength, and three axis machining had been unable to machine complex curved surfaces. 5 axis CNC machining was the only method that could work.

JS Precision Solution

1.DFM Collaborative Optimization:

After combining the features of complex parts 5-axis machining, the engineers proposed raising some very sharp internal angles from R2 to R3. They checked using tolerance analysis software to make the tolerance zones in non-critical areas equal. This allowed them to machine more easily, risk of tool interference was lowered, product performance was maintained at the same time.

2.Dedicated Tooling and High-Speed Strategy:

To suit the cutting characteristics of Ti6Al4V titanium alloy, a dedicated vacuum fixture was designed. Vacuum pressure was accurately adjusted at 0.08MPa in order to maintain the rigidity of the thin-walled part.

A high-speed (12000 rpm), shallow depth-of-cut, and fast-feed cycloidal milling approach was used for the working time being significantly reduced and the thermal deformation being kept within 0.005mm.

3. Five Axis Continuous Finishing:

A 6mm coated carbide ball end mill was applied. To finish all curved surfaces, a five axis continuous interpolation algorithm was utilized, which also allowed the surface quality to be consistent and thus the contour accuracy to be achieved. Manual polishing afterward was unnecessary, which largely cut down the labor costs and the risk of secondary damage.

Results

The component was milled out of a single titanium blank, thus the first functional prototype, which complied with all the design requirements, was successfully produced.

The single-piece machining time was brought down from the estimated 18 hours to 5 hours, thus the costs were reduced by 45%. The part survived a 150% load fatigue test and was 35% lighter than the original welding solution, which led the customer to make a small, batch order.
