Northstar Aerospace Increases Efficiency with New Technology
January 1, 2016
Northstar Aerospace, an independent manufacturer of helicopter transmission components, recently purchased, through Morris Midwest, Illinois, an Okuma MULTUS B750 horizontal lathe to increase efficiencies in its production schedule. The B750 handles critical tolerances that are necessary when machining aerospace parts. Northstar also discovered it could improve its efficiencies by fine-tuning cutting processes, minimizing operator work handling and using technologies developed by Okuma's Partners in THINC members. Following this installation, Northstar added another Okuma machine tool-an LB35III horizontal lathe.
The MULTUS B750 utilizes the latest in CNC machine technologies to maintain tight tolerances when cutting transmission parts on heat-treated material (40-50 Rockwell). Additionally, Okuma's Collision Avoidance Software (CAS), standard on the MULTUS, is designed to aid in increasing shop floor efficiencies by integrating 3-D modeling of Okuma machines, tooling and part blanks with the OSP-P control. This creates a virtual machine that runs real-time virtual applications to detect cutting problems and prevent time-consuming, costly crashes.
The technologies of the MULTUS B750 are designed to make it possible to limit operator intervention and work handling. Northstar went a step further working closely with an Okuma application engineer to fine-tune cutting processes. "They discovered that by changing up the order a part is cut, distortion is minimized resulting in improved process efficiency. The collaboration worked well because each member of the team brought a unique perspective and knowledge to the project, allowing process change and development that otherwise, would not have occurred," said a company spokesperson.
The set-up on the B750 also includes technologies from Partners in THINC that help create even more efficiencies.
Partner technologies:
- A Renishaw probe is used for in-process gauging, which allows the machine to check the part itself, without operator intervention
- CAD/CAM software programming by ESPRIT provides part cutting solutions that incorporate the gauging into the post processor G-code
- Tool Monitor Adaptive Control (TMAC) from Caron Engineering monitors electric current load to the turning and milling spindle and will stop the machine if loads exceed the established values. This also has an adaptive feature that increases or decreases cutting feedrates if loads are within a safe cutting range
- A high pressure coolant system from MP Systems provides better coolant flow to the cutting tool and helps extend tool life.
