Navigation: linear friction welding adaptive processing

Application object：An aviation technology company

Adaptive machining software is an intelligent software tool for aerospace parts repair in CNC machining scenarios, in order to improve the processing quality of parts and realize the closed-loop control of "online measurement-quality analysis-adaptive adjustment" of zero equipment.

Customer Case

Customer pain point：

For the integral blade disk after linear friction welding, each blade has different position deviation relative to the wheel, the theoretical program of blade root position finishing can not adapt to this deviation, usually there will be a problem of uneven connection between the machining area and the welding boundary. Because each blade itself has different degrees of contour error, the theoretical program can not follow the contour deviation processing, so it will leave a cutter mark in the processing area and the welding boundary, affecting the qualified delivery of products.

Solution & Value：

Aiming at the machining difficulties of linear friction welding blade disc, the team of Suzhou Qian Zhi Neng Technology Co., Ltd. proposed an adaptive machining scheme based on in-machine measurement and error compensation technology. The blade profile data was measured by a probe on the machine tool, and the deviation between position and profile was captured. The purpose of smooth connection between machining area and blade and qualified blade root size is achieved.
Adaptive machining of linear friction welding disc using QJCAM.Turbo and QJCAM.FIT Application advantages:
1. Using QJCAM.Turbo to prepare blade machining program efficiently and safely, through the flow path milling rough machining, blade finishing, root corner finishing output machining program.
2. Using QJCAM.FIT in the machine measurement, adaptive processing, compared with the traditional way, the processing process is convenient, fast processing speed, good processing quality.

Solution

QJCAM.Turbo assists in generating machining paths
QJCAM.Turbo has a complete library of integral disk machining strategies. The machining tool path with uniform blade root allowance is generated by the layer milling and roughing of the runner, and the semi-finishing step of the blade is completed at the same time. The blade finishing tool path is used to generate the blade milling tool path, and the blade finishing step is completed.

QJCAM.FIT Fast clamp parts alignment
Because there is no angular feature on the wheel, it is necessary to use QJCAM.Fit quick clamping for part alignment to avoid the situation of firing pins in the measurement process due to angular deviation. By placing points on the blade to measure, the best fitting calculation method is used to measure the data to ensure that the coordinate system of the measurement project coincides with the Angle of the part.

QJCAM.FIT integral blade disc measurement and adaptive machining
After the part of the blade machined in place is welded to the working table of the wheel by linear friction welding technology, there is a position deviation between the blade and the wheel. The QJCAM.Fit blade disc repair module ADAPTS the finishing tool path of the blade root to ensure smooth connection between the machining area and the welding part by measuring points on the blade, and gradually converges the deviation of the blade position and profile to the qualified tolerance range.

QJCAM.Fit automatic processing
The automation function of QJCAM.Fit can package the quick clamping and blade disc repair modules. Under the premise of establishing communication with the machine tool, the measurement program is automatically sent to the machine tool, the measurement is driven by the machine tool, the measurement results are returned, and the adaptive processing is completed. The whole process has no manual intervention, and the whole line of automatic production is realized.
