I need a production-ready design for a double-acting welded hydraulic cylinder that will be installed on industrial machinery. Key metrics are a 1 830 mm stroke, 75 mm Ø tube (63 mm bore), and a 45 mm chrome-plated rod. The assembly must cope with elevated operating temperatures, corrosive splashes, and heavy-duty cycles, so every decision on steel grade, seal selection, and surface finishing has to reflect those conditions. Once we start, I will share the exact mounting style and the pressure range (assume 250–300 bar for your preliminary work). What I expect from you is a complete engineering package: • Fully dimensioned 2D drawings and 3D CAD model (STEP or native SolidWorks) • Strength, fatigue, and buckling calculations with clear safety factors • Sea...

I need reliable, quick-turn estimates for our custom sheet-metal jobs so the shop can quote faster and schedule machines with confidence. All of the work originates from SolidWorks models and is processed on our lasers and other CNC equipment. Typical parts are cut from steel, aluminum, and stainless steel in the 2 mm – 5 mm range, then formed and finished in-house. What I’m looking for is someone who can open the SolidWorks file, determine flat-pattern size, nest efficiency, and calculate both raw material usage and the true machine time—piercing, cutting, tool-change, and any secondary ops—so I can drop those numbers straight into our quoting sheet. If you already use built-in SolidWorks costing, third-party plug-ins, or your own spreadsheet, that’s fine as...

I’m new to AutoCAD and want a patient, knowledgeable tutor who can walk me through the software from the ground up. We’ll begin with the fundamentals—navigating the interface, setting up drawings, and using core drafting tools—then progress at a pace that matches my understanding. What I’m looking for: • Live, screen-share sessions (one to one video call) where you demonstrate, then let me try in real time. • Clear explanations of best practices so I build good habits early. • Short practice exercises or mini-assignments after each lesson, with feedback on my files. • Gradual introduction to more advanced features once I’m comfortable with the basics. Please outline your teaching approach, typical session length, and any mater...
