A physical sample provides a starting point when design files are unavailable. Wear or damage can make original dimensions uncertain, so include information about fit, function and mating parts. A scan is not proof of original design intent or ownership rights. APT works with clients across the whole of the UK and internationally: send your models and files, we manufacture the parts in-house and deliver them by courier. Industries served include aerospace, defence, motorsport and medical, with a strong R&D and prototype focus. The risk ## Planning Your Reverse Engineering Enquiry A physical sample provides a starting point when design files are unavailable. Wear or damage can make original dimensions uncertain, so include information about fit, function and mating parts. A scan is not proof of original design intent or ownership rights. ### Drawing requirements Identify the dimensions and features that control fit and function. Include the drawing revision and material grade. ### Physical sample If drawings are unavailable, a physical part can be scanned and modelled to produce full drawings. Explain any known wear or damage. ### Required date Include your target date and discuss feasibility. Overnight and weekend machining is available when needed. ### Inspection requirements Specify whether you need CMM inspection and an inspection report. Reports are supplied on request. Our process ## How Your Job Runs, Step by Step - 01 ### Physical part Send a physical sample and information about its function. - 02 ### Scan The physical part is 3D scanned. - 03 ### Model A model is produced from the scan. - 04 ### Full drawings Full technical drawings are produced. - 05 ### Manufacturing enquiry Discuss any requirement for replacement parts and inspection with APT. What you get ## The Difference It Makes ### Small-batch focus One-offs, prototypes and typical batches of 1 to 100 parts. ### Machining experience Founded and wholly owned by Thomas White, a precision engineer with 27 years of machining experience. ### Confidentiality as standard An NDA is signed with every customer. ### Certified systems ISO 9001, ISO 14001 and Cyber Essentials certified. ### Flexible capacity Additional specialist capacity and overnight and weekend machining are available when deadlines demand it. ### Inspection on request 5-axis scanning CMM inspection reports on request, including for parts made elsewhere. In detail ## Reverse Engineering: Capability and Enquiries Confirmed equipment, capabilities and requirements for discussing your project. ### Typical reverse engineering jobs Common work includes obsolete machine parts, legacy test equipment components, inherited designs with no documentation, prototype parts hand-modified during development and components from suppliers who have ceased trading. Housings, brackets, shafts, gears and sealing faces all come through our manufacturing facility regularly. ### Machining equipment and software APT uses DMG MORI CMX 70 U and Matsuura MX-520 5-axis milling machines, with OPEN MIND hyperMILL and Autodesk Fusion for CAM programming. Machining tolerances are 5 to 10 microns (0.005–0.010 mm). ### Machining size and batch range Maximum machining part size is 675 mm × 650 mm × 550 mm (X × Y × Z), with cylindrical parts up to 600 mm diameter. Typical batches are 1 to 100 parts; one-offs and prototypes are welcome. Contact APT about the suitability of your particular part. ### Materials Materials machined include aluminium, stainless steel, titanium, plastics and exotic alloys. APT has also machined glass and carbon. Please specify the material and grade in your enquiry so suitability can be discussed. ### Inspection and certification APT holds ISO 9001 quality management, ISO 14001 environmental management and Cyber Essentials certification. A 5-axis scanning CMM is used for inspection, with inspection reports supplied on request. Standalone inspection is also available for parts made elsewhere. ### Files and confidentiality STEP, IGES and technical drawings are accepted. An NDA is signed with every customer as standard. If no drawing exists, send a physical part for scanning, modelling from the scan and production of full drawings. ### Team and availability A trusted team of CNC programmers, machinists and inspectors, built up over 20 years, supports our in-house manufacturing capabilities. Opening hours are Monday to Friday, 7am to 6pm, as previously confirmed for this website. 24/7 machining is available, including overnight and weekend running when needed. Contact APT to discuss your required date and availability; extended running does not mean every deadline can be met. ### Related capabilities 3D Scanning & Technical DrawingsCMM InspectionManufacturing FAQs ## Common Questions ### What tolerances can you hold? +Machining tolerances are 5 to 10 microns (0.005–0.010 mm).
