12.61% Improved Processing Efficiency! Unveiling How SIGER Data's Adaptive Machining System Saves 15 Seconds for Dual-Spindle Composite Machines!

Company       News Date：2026/09/28

In a precision manufacturing workshop, a batch of dual-spindle, dual-turret machining centers are undertaking the precision machining of a large number of thread conversion joints. These parts involve multiple complex processes including turning, drilling, and threading, requiring extremely high precision in dimensional consistency, thread accuracy, and cycle time control. The operating team has long been caught in a tug-of-war between efficiency and quality:

◆  Speeding up?  During roughing, the large depth of cut and consistently high load, coupled with frequent changes in axial load and significant impact during threading, mean even slight errors can trigger vibrations, leading to out-of-tolerance thread accuracy and even abnormal tool wear.

◆  Slowing down?  During finishing, the reduced cutting allowance and rapid decrease in spindle load mean that high-speed cutting potential in idle and lightly loaded areas is wasted due to conservative global feed rates, resulting in lengthy cycle times and severely limiting the potential of dual-spindle, dual-turret machining.

With the deep involvement of the SIGER Data Adaptive Machining System (AMS), this high wall of "efficiency and quality" has been completely torn down—allowing dual-spindle dual-turret composite machining to learn "dynamic thinking" and transforming real-time load perception into a qualitative change in efficiency.

I. Addressing Key Pain Points: The "Triple Shackles" of Composite Machining for Threaded Adapters

For parts like threaded adapters, which involve alternating turning, drilling, and threading operations, the limitations of traditional constant feed strategies are particularly pronounced:

❌ Frequent Switching Between Operations, Significant Load Fluctuations

Roughing involves a large depth of cut, resulting in a consistently high cutting load; finishing reduces the cutting allowance, causing a rapid decrease in spindle load; threading involves frequent changes in axial load, leading to significant impacts. The load fluctuates rapidly throughout the entire machining process, making it difficult for a single control strategy to maintain stability.

❌ Insufficient Utilization of the Potential of Fixed-Feed Dual-Spindle Machines

Sharing parameter strategies for roughing and finishing leads to unstable cutting loads due to workpiece allowance fluctuations; to ensure thread quality, feed parameters are generally conservative, failing to fully utilize the machine tool's high power and high rigidity advantages.

❌ Reliance on Manual Parameter Adjustment Limits Efficiency

To avoid localized overloads, a large safety margin is reserved, making it difficult to balance machining stability and production efficiency, significantly reducing the return on investment for equipment.

II. Intelligent Solution: SIGER Adaptive Machining System Empowers Composite Machine Tools with "Dynamic Thinking" Capabilities

The SIGER Data Adaptive Machining System (AMS) establishes a complete closed loop of "real-time perception → AI decision-making → smooth execution",​ rejecting simplistic and crude overall acceleration and deceleration:

✅ Low-Load Speed Increase, Unleashing Equipment Performance

Based on spindle load signals and cutting characteristics of each process, the system learns the machining patterns of the first part through AI algorithms, dynamically adjusting the machine tool feed rate in real time during subsequent machining processes. During finish turning, idle feed, and light-load cutting areas, the system automatically increases the feed rate, fully unleashing the performance of the dual-spindle, dual-turret composite machining equipment.

✅ High-Load Speed Reduction, Ensuring Machining Stability

When the load approaches a set threshold during rough turning, drilling, or other processes, the system automatically reduces the feed rate to avoid tool overload and abnormal wear. Simultaneously, it identifies sudden load changes in real time and smoothly adjusts the feed curve, effectively avoiding vibration marks and ensuring thread accuracy and dimensional consistency.

✅ One program, adaptive to multiple cutting processes

Without modifying the original machining program, the system automatically learns the workpiece characteristics and process switching nodes, enabling the same program to automatically adapt to different cutting processes. While ensuring tool marks-free operation, it continuously improves equipment utilization, truly enabling the machine tool to "autopilot".​

III.​Practical Value: 12.61% Efficiency Improvement, Fully Unleashing the Potential of Dual Spindles

In a real-world scenario where this dual-spindle, dual-turret machining center was mass-producing thread conversion connectors, the SIGGRAPH AMS adaptive machining system delivered impressive results:

■ Before Modification: Single-part machining cycle time: 119 seconds

■ After Modification: Single-part machining cycle time: 104 seconds

■ Overall Machining Efficiency Improvement: 12.61% (reduced by 15 seconds)

More importantly, this improvement did not come at the expense of quality—in key stages such as roughing, finishing, and thread machining, the AMS system ensured extreme stability in the cutting process by smoothly adjusting the feed, eliminating tool vibration marks, and achieving both thread accuracy and dimensional consistency, truly realizing "stability with speed".

IV. Beyond Data: The Panoramic Value for Customers

The value of the SIGER Data Adaptive Machining System (AMS) goes far beyond simply reducing cycle time per piece. It builds a core competitive advantage for sustainable evolution in enterprises:

4.1 Unleashing Hidden Capacity

A 12.61% efficiency improvement means releasing more than one-eighth of production potential without adding equipment. With the same dual-spindle, dual-turret composite machine and the same personnel configuration, dozens more high-precision thread conversion connectors can be produced daily.

4.2 24/7 Quality Assurance

Intelligent and smooth feed adjustment effectively suppresses sudden load changes caused by process switching. Eliminates vibration marks and machining ripples, improving yield and reducing rework costs.

4.3 Digital Intelligence Accumulation

Transforming the "feel" speed adjustment experience of veteran operators into quantifiable, learnable, and reusable optimal parameter models. The introduction cycle for new processes, new workpieces, and new employees is significantly shortened.

4.4 Reusing underlying hardware to expand digital production lines

The system boasts strong foresight and scalability. Based on a pre-deployed set of underlying hardware, enterprises can seamlessly expand tool monitoring (TMS), machine spindle collision protection (TCS), machine spindle dynamic balance monitoring (DBS), thermal compensation management system (CMS), and equipment health management system (PHM) as needed in the future. This achieves a "six-in-one" solution with extremely low additional costs, steadily building a truly digital production line.
