I run a CNC router here in Riyadh that is dedicated to metal jobs, and I’m looking for practical, hands-on guidance to tighten up my day-to-day operation. The programs are already written; what I need is an expert operator who can show me the most efficient workflow—everything from powering up, tool loading, accurate zeroing, clamping for aluminium or mild steel, right through to adjusting feeds, speeds and coolant so I get consistent surface finish without excess tool wear. Ideally you can coach me live (video is fine, on-site even better) while I’m at the machine, then help me turn that session into a concise checklist I can follow on my own. Experience with common CNC controllers such as Fanuc, Siemens, or Mach3 is important, as is a solid understanding of metal machi...

I need a complete die template engineered for a rectangular-profile aluminium extrusion that will be used in a construction application. I already have the exact dimensions and will share a detailed cross-section sketch as soon as we start, so your focus can stay on translating those numbers into a production-ready tool design rather than interpreting vague specs. Here is what I’m after: • A fully detailed 2D/3D die drawing that a toolmaker can load straight into their CNC workflow (STEP or IGES plus a dimensioned PDF/DWG). • Consideration of material flow, bearing lengths, land, and exit tolerances so the final section comes out true to size with minimal post-processing. • A brief manufacturability note highlighting any critical tolerances or heat-treatment reco...

I’m ready to overhaul the current production-line arrangement in my factory and need a lean layout that measurably improves workflow. You’ll be working with an existing floor plan and real-world cycle-time data; the aim is to strip away every unnecessary movement or bottleneck so materials, people and information move in one smooth, continuous flow. The requirement is onsite in India. I will provide the present layout, process sequence charts and takt-time figures. Your task is to analyse them, propose a revised configuration grounded in lean principles and illustrate how each change removes waste and shortens travel paths. A concise justification for every repositioned machine, workstation or buffer is essential so I can make the case internally. I’m most interested in...

I’m developing an IoT device that will live permanently outdoors, so the enclosure must be tough st and attractive. The product needs to be C1D2 certified. I have sketched the basic board layout and I now need a mechanical engineer who can carry the housing from an initial requirements definition all the way through to documentation for mass production. Durability drives every decision: weather-proof seals, UV-stable plastic (I’m leaning toward a robust polycarbonate or glass-filled nylon), impact resistance, and the ability to maintain watertight integrity after repeated assembly cycles. If you feel a metal insert or composite gasket improves reliability, I’m open to those suggestions, but the core body should remain plastic to keep tooling costs and weight down. The w...

I have an early concept for a multi-purpose woodturning tool and I need someone to turn that idea into a build-ready prototype. At this stage it is nothing more than sketches and functional notes, so your primary task is to translate the concept into detailed 3D CAD and engineering drawings I can hand straight to a machinist. Core functions • Cutting and shaping • Detailing and finishing • Hollowing out The finished design must handle both hardwoods and softwoods without swapping cutters mid-project, so balance, vibration control and edge durability are critical. I am open to carbide inserts, HSS, or a hybrid tip system if it meets those goals. Deliverables 1. Parametric 3D model (SolidWorks, Fusion 360 or similar) 2. Fully dimensioned drawings with tolerances...
