Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual centering adjustment is used, then device complexity is reduced, but productivity decreases and manufacturing precision deteriorates due to time-consuming operations and human error
Solution Approach 1:
The centering probe is made dynamically adjustable during operation. The probe holder can be moved axially and radially via adjustment drives, allowing the probe position to be optimized for different workpiece diameters and machining conditions without stopping the machine, thus improving productivity while maintaining manageable device complexity through controlled dynamic adjustment
Solution Approach 2:
The adjustment drives serve multiple functions: they position the probe holder axially for different workpiece sizes, adjust the radial position for optimal measurement, and enable the probe to be retracted during workpiece changes. This multi-functionality consolidates several adjustment needs into a single integrated mechanism, improving productivity without proportionally increasing device complexity
2Manufacturing precision
If non-contact centering probes are positioned close to the workpiece outer contour for precise measurement, then manufacturing precision improves, but the risk of collision with workpiece loading device increases
Solution Approach 1:
The probe holder is designed to be dynamically repositionable during workpiece changes. The adjustment drives can quickly retract the probe axially and radially when a workpiece is being loaded or unloaded, eliminating the collision risk. During actual centering operations, the probe is positioned close to the workpiece contour for high measurement accuracy. This dynamic positioning resolves the contradiction between measurement precision and collision avoidance
Solution Approach 2:
The probe holder acts as an intermediary between the fixed probe and the workpiece. By positioning the probe holder at a safe distance during workpiece changes and only moving it close for measurement, it mediates between the need for accurate measurement and the need to avoid collision with loading devices
3Productivity
If manual adjustment of probe position for different workpiece diameters is used, then device complexity is reduced, but productivity decreases due to repeated manual intervention
Solution Approach 1:
The adjustment drives provide dynamic, automated adjustment of the probe holder position for different workpiece diameters. Instead of manual intervention, the system can automatically position the probe optimally for each workpiece size, enabling continuous operation and improving productivity. The complexity is managed by using standardized motorized actuators integrated into the existing machine control
Solution Approach 2:
The system uses feedback from the centering measurement to automatically adjust the probe holder position. The non-contact probe measures the workpiece geometry, and this information feeds back to the adjustment drives, which automatically reposition the probe for optimal measurement of different workpiece diameters, enabling continuous automated operation without manual intervention

AI summary
The invention relates to a device for machining workpieces with precut teeth, having a workpiece support and at least one workpiece spindle arranged on the workpiece support for clamping a workpiece (8). A centering device (20.1) for the workpieces comprises a probe holder (30) with a centering probe (26), which operates in a contactless manner, and a base element (37). The probe holder is connected to the base element such that the probe holder has a variable radial distance to the workpiece spindle axis. The base element is designed as a slide which can be moved relative to the workpiece support. A linear guide for the base element allows a movement of the base element relative to the workpiece support. An adjustment drive for the centering device can be arranged above the centering device on a backrest of the workpiece support.
