| | Project: SCREW PRESS ASSEMBLY — REVIEWING FINISHES, FITS AND TOLERANCES BEFORE MACHINING | | Date: 02/24/2026 | | Prepared by: Markus Hormaza, representative of ASAP PROJECTS © | | Objective: To execute the complete technical development of critical mechanical components for a screw press assembly, with a focus on additive prototyping for validation followed by precision CNC machining. The project employs parametric design (CAD) to create manufacturable geometries, utilizes 3D printing for functional prototyping and fit-checking, and generates optimized toolpaths (CAM) for final production, ensuring all components meet stringent industrial manufacturing criteria | | Development Phase: Detail engineering, additive prototyping (functional verification), and preparation for final machining | | Project Scope: End-to-end development of load-bearing mechanical components, from digital model to physical prototype to machined part. The scope encompassed: Parametric 3D modeling of components – Functional additive prototyping (3D printing) – Design and validation of critical contact surfaces and interfaces – Digital interference and assembly simulation – Generation of ASME/ISO-compliant technical drawings – Development of CAM strategies for milling and drilling – Definition of geometric dimensioning & tolerancing (GD&T) and manufacturing limits | | Standards: ISO 2768 (General Tolerances), ISO 1101 (Geometrical Tolerancing), ASME Y14.5M (Dimensioning and Tolerancing), DIN 7168 (Fits) | | Design for Manufacturing Requirements: Components were designed for fabrication on 3-axis CNC machining centers. Machining strategies were developed for roughing, semi-finishing, and finishing operations. Critical functional surfaces (e.g., guide columns, ram interfaces) were specified with H7/f7 sliding fits and surface finishes of Ra 1.6 μm in wear-prone zones. A fully associative CAD-CAM workflow ensured direct generation of production-ready G-code from the master model | | Skills: Mechanical design & technical drawing. Functional additive prototyping & fit-for-purpose validation. Advanced parametric solid modeling. Application of GD&T per ISO/ASME. Kinematic motion simulation. Finite Element Analysis (FEA) for component validation. CAM programming & toolpath optimization. Design for Manufacturability (DFM) validation | | Technologies Used: AutoCAD Mechanical – Autodesk Fusion 360 (Full CAD/CAE/CAM Suite) | | LOD (Level of Development): LOD 350 – Model and documentation detail sufficient for fabrication, including precise geometry, assembly specifications, and finish requirements | | Components Developed: Screw press base – Main power screw (ram) – Movable platen – Guide columns & linear bearing surfaces – Structural support frame – Custom fastener set – Fully toleranced assembly model | | Publication URL: https://hormazamarkus.wixsite.com/zlayerplus | | Scope: Master 3D CAD Assembly Model – ASME-Compliant Technical Drawing Package (PDF) – Functional 3D Printed Prototype (STL) – Production CAM Files & G-code for CNC Machining | | Key Development Highlights: Precision parametric modeling of mechanical components – Additive prototyping for functional form, fit, and assembly verification – Optimized CNC machining sequences (roughing to finishing) – Rigorous dimensional and geometric tolerance control – Specification of functional surface finishes – Seamless CAD-to-CAM data interoperability – Provision of digital files for all manufacturing stages | | Technical Considerations: (1) This project demonstrates a robust, integrated workflow for mechanical component development, where additive prototyping is strategically used to de-risk the subsequent CNC machining phase. The precise definition of fits, finishes, and tolerances in the digital model guarantees the performance of the final mechanical assembly. (2) A high-fidelity, multi-component 3D print in engineering-grade ABS served as the primary functional prototype. This critical step enabled empirical validation of assembly kinematics, identification and correction of spatial interferences, and adjustment of operational clearances prior to metal cutting. The use of additive prototyping within this workflow proved indispensable for preventing costly design errors, reducing lead time for corrections, and providing a tangible reference for workshop communication, ensuring manufacturability and final product quality | | Contact: Markus Hormaza, hormazamarkus@gmail.com | | Rights: ASAP PROJECTS ©.
