In today’s precision manufacturing world, balancing machining accuracy and production efficiency remains one of the biggest challenges. Traditional measurement methods on CNC machines are slow, highly dependent on manual intervention, and often introduce inconsistent results. These limitations reduce productivity and increase scrap rates.

As a specialist in in-machine measurement technology, Qidu Metrology introduces a breakthrough solution: Online Automatic Measurement + Coordinate Dynamic Compensation. By integrating CNC probe measurement and tool setter compensation into a closed-loop system, this solution eliminates manual measurement, stabilizes machining accuracy, and dramatically improves production efficiency.

1. Technology Innovation: From Passive Measurement to Active Compensation

Traditional CNC measurement processes create several bottlenecks:

Workpieces must be removed repeatedly, introducing clamping errors
Manual measurement depends on operator experience
Offline inspection interrupts machining
Data recording is inefficient and error-prone

Statistics show that traditional manual measurement requires 2 hours of downtime per batch, operators spend 3 hours daily recording data, and scrap rates can reach 8%.

Qidu’s CNC probe + tool setter closed-loop solution solves these problems through three key innovations.

Real-Time Online Measurement Using CNC Probe

By integrating a high-precision CNC probe directly inside the machining area, workpieces can be measured without removal. The probe follows programmed paths, touches target surfaces, and records trigger points automatically.

Key advantages:

Real-time in-process measurement
Automatic coordinate recording
No manual intervention
Measurement accuracy within 0.002 mm
Compatible with 3-axis, 4-axis, and 5-axis CNC machines

This transforms traditional offline inspection into fully automated in-machine measurement.

Multi-Axis Dynamic Compensation with Tool Setter Integration

The system performs real-time compensation across 1–6 axes using measurement feedback from the CNC probe and cutting data from the tool setter.

Compensation includes:

Geometric errors
Thermal deformation
Cutting force deviation
Tool wear compensation
Machine positioning drift

Using CNC external coordinate offset, the system dynamically corrects axis positions, keeping deviation within 9 microns and reducing thermal deformation by up to 88%.

Intelligent Closed-Loop Control System

The solution integrates:

Machining → CNC probe measurement → compensation → re-machining

This intelligent loop automatically detects machine errors, applies compensation, and verifies results. Compared with dial indicators and manual gauge rods, this system provides:

Higher accuracy
Faster measurement
Full digital traceability
Reduced operator dependency

2. Customer Case: Leading Consumer Electronics Manufacturer

Qidu has established deep cooperation with leading precision component manufacturers in the consumer electronics industry. These companies supply structural components for smartphones, camera modules, and wearable devices.

Before adopting Qidu’s CNC probe + tool setter solution, the customer faced major challenges:
