SolidWorks
What is SOLIDWORKS?
SOLIDWORKS is a 3D CAD software that is widely used in mechanical design, machine building, and the manufacturing industry. The software is based on parametric solid modeling, where the geometry of parts and assemblies is defined by dimensions, constraints, and design rules. This allows design solutions to be easily modified, with changes updated in a controlled manner throughout the model-based dataset. SOLIDWORKS is especially suited for designing mechanical parts and structures where manufacturability, dimensional accuracy, and documentation are key requirements.
SOLIDWORKS is part of the Dassault Systèmes group and is widely used in both individual machine shops and large industrial production environments. The software has established itself as a tool that closely connects design and manufacturing.
SOLIDWORKS as a Design Tool in Manufacturing
In manufacturing, SOLIDWORKS often serves as the starting point of the design chain, from which information is passed on to machining, CAM programming, and production. The 3D model is not just a visual representation of a part—it contains the geometry, dimensions, and structural logic defined by the designer, which serve as the basis for manufacturing. This reduces ambiguity between the machinist and designer and improves production predictability.
SOLIDWORKS is especially well suited for subcontracting machine shops where products vary and changes are frequently made at short notice. Its parametric structure allows for quick changes, such as adjusting a shaft diameter or sheet metal thickness, without having to rebuild the entire model or drawing from scratch.
SOLIDWORKS and Part Modeling
Part modeling in SOLIDWORKS is based on features built from sketches, extrusions, revolves, and other basic operations. This approach corresponds closely to actual machining steps such as turning, milling, and drilling. The modeling process can take into account things like wall thicknesses, tool reach, chamfers, and fillets, all of which directly impact part manufacturability in the shop.
SOLIDWORKS also supports the use of standard components and ready-made features, which accelerates the design process and improves consistency. When models are built logically and with manufacturing in mind, they are well suited for further use in CAM software and CNC machining.
SOLIDWORKS Assemblies and Structure Review
Assembly functions are a key part of the SOLIDWORKS software. Individual parts can be combined into assemblies, where their relationships, movements, and positions are defined by mates. This enables users to review structure operation during the design phase—before physical production.
For machine shops, assemblies help visualize part fits, assembly sequences, and potential interferences. This can reduce errors that would otherwise be detected only during assembly or commissioning. Assembly models also support the creation of parts lists and assembly drawings.
SOLIDWORKS and Technical Drawings
Technical documentation is an essential part of manufacturing, and SOLIDWORKS enables the creation of drawings directly from 3D models. This reduces discrepancies between models and drawings and improves the reliability of information. Drawings can include dimensions, tolerances, surface markings, and other manufacturing-critical information.
For machinists and those responsible for measurement, the clarity and consistency of drawings are crucial. SOLIDWORKS supports standardized drafting, making communication easier both within the shop and with customers.
SOLIDWORKS and Simulation as a Design Aid
SOLIDWORKS includes simulation tools that enable the assessment of structural strength and load behavior before manufacturing. Simulation does not replace physical testing, but it helps identify structurally weak points and steer the design in a more functional direction.
In manufacturing, the benefit of simulation is especially apparent when producing loaded structures, fasteners, or machine parts where functionality is critical. Proactive review can reduce unnecessary machining trials and material waste.
SOLIDWORKS and Data Management in Machine Shops
SOLIDWORKS PDM is designed to centrally manage design data, versions, and documents. In machine shops, this helps ensure that the correct version of a model or drawing is always used for production. Version control is especially important in environments where the same product is modified multiple times or by multiple people.
Well-managed design data also supports traceability, quality control, and production planning, which are important for meeting the requirements of the manufacturing industry.
SOLIDWORKS and Data Transfer to Manufacturing
SOLIDWORKS broadly supports standard file formats, enabling smooth collaboration between different CAD and CAM systems. 3D models can be used directly in CAM software, serving as the basis for toolpaths and CNC programs. This shortens lead time and reduces manual data entry.
Summary
SOLIDWORKS is a well-established 3D CAD software that supports the design needs of machine shops and machining companies throughout the entire production chain. Its parametric modeling, assembly tools, and direct link to technical documentation make it a practical tool for the manufacturing industry's requirements. SOLIDWORKS connects design and production so that the 3D model serves as a reliable foundation for machining, measurement, and manufacturing.
