What Is The Achievable Standard And Ultimate Tolerance In 5 Axis Machining Services?

Excellent control of tolerance is one of the core competencies of 5 axis machining services, and also an important way to win customer recognition.

The basis for its accuracy evaluation can refer to the acceptance criteria for specimen accuracy in the ISO 10791-7:2020 machining center inspection condition standard, which provides an internationally recognized method for evaluating the comprehensive accuracy of 5-axis machine tools.

Standard Tolerance Range

Starting from standard production conditions, there are some benchmarks for the achievable tolerance of different materials, which is given in the table below:

Material Type	Conventional Tolerance Range	High-Precision Tolerance Range	Applicable Scenarios
Aluminum Alloy	±0.025mm	±0.005mm	Automotive parts, general machinery
Steel	±0.030mm	±0.008mm	Industrial equipment, mold parts
Titanium Alloy	±0.035mm	±0.010mm	Aerospace, implants medical

"Invisible" Factors Affecting Tolerance

1. The machine tool's static and dynamic precision: The machine tool's positioning precision and repeated positioning precision are the direct determinants of the basic tolerance, while tracking errors amplify deviation when machining a complicated surface, which affects the forming effect of this part.

2. Thermal deformation management: High speed rotation of the spindle during the processing, friction of the guiding rails, and fluctuations in ambient temperature may all result in minute deformations of machine tool components, leading to systematic errors that require targeted compensation strategies.

3. Total Tooling System Error: Just a couple of microns of runout in the tool holder will be transferred directly to the part, and the wear of the tool itself accrues with time taken for machining, directly impacting tolerance stability.

Accuracy Assurance System of JS Precision

• We strictly control the sources of precision, starting from the equipment selection stage: introducing high-end 5-axis machine tools from Germany and Japan, with positioning accuracy up to ±0.003mm.
• Meanwhile setting up a constant temperature workshop to control environmental temperature fluctuations within ±2℃.
• In the machining process, online detection equipment is used to monitor dimensional deviations in real time, with parameter adjustments through process compensation algorithms.

It is this system that allows our 5 axis machining services to keep output stable and of high precision consistently.

The Art Of Complexity: How To Machine Demanding 5-Axis Aerospace Components?

5-axis aerospace components are usually characterized by complex curved surfaces and thin-walled structures. Consequently, machining these parts turns out to be very challenging and requires scientific process planning and execution methodologies to be successful.

Process Planning: Beginning with Simulation

1. Virtual Manufacturing and Collision Detection:

The structure of 5-axis aerospace components is complicated. Even slight mistakes in the machining path lead to collisions between the tool, workpiece, and fixture.

We use advanced CAM software to build a complete virtual machining environment, simulate trajectories of machine tool motion, and identify collision risks in advance to avoid expensive material waste and equipment damage.

2. Cutting Force and Deformation Prediction:

The thin-walled structure in the aerospace parts is usually less than 2mm thick and easily deformed by the cutting force. We predict the trend of parts deformation under different cutting parameters through finite element analysis, optimize the cutting sequence and feed rate, and control the amount of deformation actively.

Execution Strategy: Stability First

1. Clamping Method Selection:

According to the characteristics of the 5-axis aerospace components, we flexibly select the method of machining. Parts with complex structures should be subjected to continuous 5-axis machining to accomplish all processes in one clamping, in the case of parts with poor rigidity, 3+2 axis oriented machining should be used to improve machining stability.

2. Dedicated Fixtures & Zero-Point Quick-Change System:

Minimize the effect that clamping force has on the parts while improving the clamping rigidity with our designed fixtures. The zero-point quick-change system allows for rapid changeovers, reducing preparation time in mass production and improving overall efficiency.

Understanding Cost Drivers In Difficult Titanium 5-Axis Machining

Titanium 5-axis machining has been consistently expensive due to its unique material properties. Thereby, only when the cost structure is made well understood, effective cost reduction strategies can be found.

Cost Structure: In-depth Analysis

The cost of titanium 5-axis machining mainly comes from three parts, with the following proportions:

Cost Type	Percentage Range	Core Influencing Factors
Direct Material Cost	30%-40%	High price of titanium alloy blanks, material utilization directly affects cost.
Machine Tool Time Cost	40%-50%	The low thermal conductivity of titanium alloy results in a slow cutting speed and a long processing cycle.
Tool Consumption Cost	10%-20%	High price of specialized tools, fast wear rate, more frequency to replace.

Approach to Cost Reduction and Efficiency Improvement by JS Precision

1. Process Parameter Optimization Library:

We have developed a dedicated parameter library based on thousands of titanium 5-axis machining experiments, which can match the cutting requirements for different titanium alloy materials accurately, such as Ti-6Al-4V, to reach a better balance between material removal rate and tool life.

2. Application of HPCT:

We have introduced a high-pressure cooling system that, with the aid of a high-pressure jet, breaks through the thermal barrier formed during machining of a titanium alloy, promptly removing chips and cooling the cutting edge.

This has significantly improved the conditions for performing cuts, with an extension of tool life by over 30%, which proportionally reduces the costs of tools consumed.

Efficiency Unlocked: When And How Does Continuous 5-Axis Machining Save Time?

Continuous 5-axis machining is a very effective way of 5-axis machining but not applicable to all occasions. Whereas in some special cases, it can greatly shorten the production time.

Where are the actual time savings?

1. Reduces setup number and datum transformations:

Conventional machining of complicated parts requires multiple setup and alignment processes, which is not only time-consuming but also introduces cumulative errors. Continuous 5-axis machining can complete all feature machining in one setting. Time required for set-up, alignment, and repeated inspection can be saved, avoiding possible cumulative errors.

2. Optimizing tool accessibility:

For deep cavities and complex curved surfaces, continuous 5-axis machining can adjust the posture of the machine tool and use shorter tools to machine. The rigidity of shorter tools is higher, which allows higher cutting parameters, considerably improving the metal removal rate and shortening the machining cycle.

Not Always the Best Solution

Continuous 5-axis machining also has many limitations: the programming difficulty is far greater than that of traditional machining, it requires professional CAM engineers for longer programming time. Meanwhile, multi-axis linkage of the machine tool increases the dynamic load, so the precision and stability of the equipment need to be further improved.

In some high-precision, small-allowance finishing cases, high-speed 5-axis machining can attain higher efficiency with faster feed rates and smoother cutting motions.

Taming The Heat: Advanced Strategies For Thermal Management In Titanium Machining

In addition, the fundamental reason for rapid tool wear and decreased part accuracy in heat accumulation is significant during titanium 5-axis machining, therefore, effective thermal management becomes very important.

The Dilemma of Heat Generation and Conduction

The thermal conductivity of the titanium alloy is only about l/4 of that of iron and about 1/16 that of aluminum. During the process of machining, because the heat brought out by cutting is not easy to be taken away, more than 90% of the heat gathers in the point of the tool.

This will not only accelerate tool wear and decrease tool life but also result in excessive local high temperatures in the part, thermal deformation, and tolerance inaccuracy.

Solutions of Systematic Heat Dissipation

1. Internal Tool Cooling: We use specialized tools with a number of internal cooling channels. The coolant moves through these directly to the cutting edge, thus precisely cooling the heat-producing core area and not allowing the dissipation of heat.

2. Coolant Selection and Pressure: High-performance cutting fluid specifically designed for titanium 5-axis machining, with great cool and lubrication effect, is employed, meanwhile, an ultra-high-pressure cooling system (>70 bar) is adopted in order to enhance the permeability of coolant to fast remove chips and heat.

3. "Thermal-Aware" Optimization of Cutting Parameters and Paths: Cycloidal milling and helical feeding are used to avoid the continuous friction and heat generation on the same area, while the cutting speed and feed rate are reasonably adjusted at the same time to decrease the amount of heat generated per unit time.

Figure 3:Five axis CNC machining can reduce heat accumulation and minimize tool wear, effectively challenging titanium machining.

Pushing The Boundaries: What Are The Practical Limits Of High-Speed 5-Axis Machining?

High-speed 5-axis machining can greatly improve processing efficiency, but due to the limitation of physical conditions and engineering technology, the speed will not be infinite. However, it has an irreplaceable advantage in certain fields.

Physical and Engineering Constraints on Speed

1. Machine Tool Dynamics Limits:

The acceleration capability of the spindle and the response speed of the servo system determine the maximum feed rate of high-speed 5-axis machining. In our high-end machine tool spindles, the maximum speed could be up to 24,000 rpm and the maximum feed rate for each axis is 60 m/min for most of the high-speed machining needs.

2. The Boundaries of Tooling Technology:

The dynamic balance level is very important under high-speed rotation, an unbalanced tool may break. Tools with a dynamic balance level of G2.5 and high-precision clamping systems are used to ensure the stability and accuracy during high-speed rotation.

3. Programming and Control Challenges:

In high-speed machining, the "look-ahead" processing capability of the CNC system becomes particularly critical. Our equipment is equipped with a high-end CNC system that can analyze more than 1000 segments of machining code in advance, avoiding pauses or overcutting at corners and hence allowing smooth machining.

Exquisite application in medical equipment processing

5-axis medical device machining needs extremely high precision and surface quality, high-speed 5-axis machining perfectly meets such requirements.

Given the small size and geometric complexity of some orthopedic implants, such as artificial joints, or surgical instruments, high-speed 5-axis machining can be done at high feed rates with a small cutting depth. This not only raises efficiency but also reduces cutting marks on the part surface, achieving an excellent surface finish that meets the requirements of biocompatibility.

The client used to adopt the traditional three-axis machining process, with several steps of clamping, resulting in as long as 18-hour single-piece machining time, and serious thin-wall deformation, which leads to a product pass rate of only 70%. It cannot meet the needs of mass production.

JS Precision Solution

We have formed a specialized technical team and developed an integrated solution for the titanium 5-axis machining project.

1. Firstly, we adopted the continuous 5-axis machining strategy and designed some special fixtures to complete the machining of all features in one setup completely, which would avoid positioning error and risks of deformation caused by multi-setups.

2. Based on our self-owned database of titanium 5-axis machining, optimize the cutting parameters to increase the material removal rate in the rough machining process, and adopt a high-speed 5-axis machining method in thin-wall areas with small depths of cut and high feed rates to reduce the cutting force.

3. Finally, in the whole process of the manufacturing, we also introduced an on-machine measurement system to measure all critical dimensions in real time, compensating automatically for tool wear and expected deformation.

Results:

With this solution, the single-piece machining time of this titanium alloy bracket was reduced from 18 hours to 6 hours, with a production efficiency increase of 200%, thin-wall deformation was controlled within ±0.015mm, and the product pass rate increased to 98%.
