Frequently asked questions (FAQ) about CAD for machine design

What is a machine?

Machines are physical systems that convert power into action. Examples of simple machines are the wedge, the lever, and the pulley. Complex machines have many parts that work together, including mechanical, electrical, and electronic components. Many modern machines are computer controlled and are programmed and monitored using a software interface.

What is machine design?

Machine design is the process of imagining and creating physical systems that meet the needs of customers in industries such as energy, aerospace, automotive, agriculture, marine, and manufacturing.

 

The machine design process includes understanding the physics needed to transform power into action to complete the intended task, planning component interactions, ensuring proper fit within design constraints, and specifying materials while considering project timelines and profit margin.

 

Technical drawings and 3D computer-aided designs (CAD) models are typically created to communicate and review the design and to coordinate the design process among stakeholders.

 

The final output of the machine design process is the information required to make, commission, and service the design, and may include technical drawings, a written specification, and a bill of materials (BOM).

 

Jobs in machine design could include industrial designer; mechanical, electrical, or electronic engineer; simulation specialist; CAD designer; and CAD drafter.

What do machine designers do?

Machine designers use mathematical principles, engineering physics, industry knowledge, and specialist software to address customer problems and develop an idea for a machine from its conceptual stage to a detailed design.

 

The detailed design must meet customer requirements and be delivered profitably. The design is communicated to stakeholders such as customers, manufacturing, and procurement via a computer-aided design (CAD) model, technical drawings, a bill of materials (BOM), and a specification.

 

Machine design is collaborative and can include multiple disciplines including industrial design and mechanical, electrical, and electronic engineering, and also includes feedback from customers, suppliers, manufacturing specialists, and project management teams.

What is the machine design process?

The design engineering process is crucial for successful machine design businesses. The objective of design development is to imagine and agree on a machine that benefits both customers and the business. Design development is constrained by budget, engineering capacity, and time to market.

 

The machine design process is collaborative and may involve specialists in disciplines such as industrial design, mechanical, electrical, and electronic engineering working together. Feedback can be included from stakeholders such as customers, project management, procurement, manufacturing, installation, and servicing.

 

The machine design process is iterative and cyclical, with ideas undergoing multiple rounds of prototyping, testing, evaluation, and review until the final design is considered optimal and reliable enough for production.

 

The machine design process starts by defining the problem, then brainstorming potential solutions before creating prototypes, testing them, gathering feedback, and evaluating whether the problem statement can be further refined, whether to reject or accept the proposed solutions, or whether the solutions can be improved with another development cycle.

What is machine design software?

Machine design software helps designers by automating tasks, tracking processes, and enabling collaboration among designers and stakeholders such as project management, procurement, manufacturing, or customers.

 

Examples of machine design software include 3D computer-aided design (CAD) software, which designers use to create virtual models of their designs to help calculate the physics of the design or to ensure that moving components won’t clash. This saves time in prototype creation. Additionally, technical drawings can be created from the 3D CAD model, reducing the time it takes to document and communicate the design.

 

Computer-aided engineering (CAE) (US Site) software helps designers to create simulation studies that automate the calculation of stress, fluid flow, thermal dynamics, and vibration, which saves time in physical prototype testing.

 

The increased accessibility of cloud-based data management is accelerating the use of model-based definition (MBD), or the use of the 3D CAD model to drive downstream manufacturing processes, reducing the need for technical drawings.

Which software is used to design machines?

Software to design machines can include:

  • Computer-aided design (CAD): 3D CAD is used to create virtual models of mechanical, electrical, or electronic components and their relationships. Technical drawings and a bill of materials (BOM) are automatically generated from the 3D model.
  • MCAD: This refers to CAD software that is specifically optimised for mechanical design, including tools to design mechanical elements such as shafts, gears, springs, cams, belts, bolted connections, and structural frames.
  • ECAD: ECAD software is specifically optimised for electronic or printed circuit board (PCB) design, including schematics, 2D trace layout, and 3D modeling.
  • Visualisation: Visualisation software is used to create computer-generated imagery (CGI) or digital renderings of designs to help communicate the design to customers or partners. Renderings can be photorealistic still images or animations showing how the design is assembled or operates.
    • Virtual reality (VR) or augmented reality (AR) software and hardware can be used to allow humans to interact directly with CGI to help visualise the design, or to train operators in a safe environment.
    • Digital twin augments the CGI with data from sensors embedded in the machine to optimise the maintenance and operation of the machine and its supporting services.
  • Computer-aided engineering (CAE): CAE or simulation software is used to analyse the performance of a design. Examples include finite element analysis (FEA), used to simulate stress, or computational fluid dynamics (CFD), used to simulate the flow of liquids and gases.
  • Tolerance analysis: Tolerance analysis is used to automate the calculation of tolerance stackups and optimise tolerances to ensure the feasibility of interchangeable parts while minimising the cost of manufacture.
  • Generative design: Generative design (US Site) is a unique approach that differs from simulation, or lightweighting. While simulation uses a 3D CAD model of a component to analyse the effects of stress on the design, generative design works the opposite way. The designer sets constraints, such as physical loads, materials, and manufacturing methods, and generative design generates multiple models of viable components that meet the performance criteria. The designer can then eliminate design options based on factors such as weight, safety factor, cost, or aesthetics, finally selecting their preferred design from the options remaining.

What software is used for mechanical drawing?

Mechanical drawings are technical drawings created to communicate design intent, diagram processes, calculate folded sheet metal flat patterns, optimise fabrication with nesting, or provide instruction for installation and maintenance. Mechanical drawings are created by design software that falls into the computer-aided design (CAD) category.

  • CAD software like Autodesk AutoCAD automates the traditional process of 2D technical drawings, with tools such as copy and paste, blocks, and the sheet set manager.
  • CAD software like Autodesk Inventor takes drawing automation a step further, by generating mechanical drawings directly from a 3D CAD model created by the designer. This can speed up the process of mechanical drawing creation and ensures that any updates to the design are automatically reflected in every drawing that references the model.
  • CAD software like Autodesk Fusion 360 brings together design, engineering, electronics, and manufacturing software all in one —connecting the entire product development process into one integrated, cloud-based software including 3D CAD, CAM, CAE, and PCB.

What is the best mechanical design software?

The best mechanical design software is computer-aided design that has been optimised for the mechanical design process (MCAD). When evaluating MCAD software, look out for the following:

  • 3D modeling of parts and assemblies to conceptualise the physical dimensions and spatial relationships of the design
  • Extendable libraries of mechanical and electrical components such as nuts, bolts, washers, O-rings, bearings, keys, cogs, belts, and springs
  • Mechanical design accelerators to automate the design and modeling of items such as bolted connections, shafts, cams, and pulley systems
  • Specific tool sets that automate the design and modeling of sheet metal components, structural frames, PCBs, cable harnesses, piping runs, and plastic enclosures
  • The ability to use CAD models to assess designs for physical properties such as stress, thermal, vibration, and fluid flow
  • The ability to implement model-based design (MBD) with tools for model-based annotation (MBA), geometric dimensioning and tolerancing (GD&T) and tolerance stack-up analysi
  • Visualisation tools to create computer-generated imagery (CGI) for communication, sales, and marketing, including photorealistic renderings, and animated videos
  • The ability to collaborate by securely sharing designs for feedback, review, and sign-off
  • The ability to collaborate on a shared CAD model with specialists in other industries, such as structural design, civil design, or BIM
  • The ability to use the CAD model for manufacturing preparation tasks like manufacturing drawings, bill of materials (BOM) creation, sheet metal nesting, and CNC programming
  • Integrated product data management (PDM) to securely manage files with permission controls, a release process, and engineering change orders

How does machine design software benefit businesses and professionals?

Businesses that manufacture machines as products feel the pressure of providing innovative solutions to meet customer demands and releasing them to market before their competition can.

 

The key to successful machine development lies in design engineering, which ensures that the machines not only meet customer needs but also generate profit for the business.

 

The decisions made during design development can affect the quality, components, materials, manufacturing processes, and usability of the machine over its lifecycle.

 

Machine design software like computer-aided design (CAD) and computer-aided engineering (CAE) benefit businesses and professionals by automating design processes and managing data insights, enabling designers and engineers to make timely and effective decisions that increase the success of the product, aiding operational efficiency, and improving time to market.

What is CAD used for in manufacturing?

Computer-aided design software (CAD) is used at multiple points in the manufacturing process.

 

During the design phase, CAD designs are shared with the manufacturing team to assess the design for manufacturing and assembly (DfMA). Feedback from the manufacturing team can be incorporated into the design, helping the design be more efficient, and therefore more profitable, to manufacture.

 

When design development is complete, designs are released for manufacture. CAD is used by the manufacturing team in the design of jigs, fixtures, and “stop-go” devices for quality control.

 

Computer-aided manufacturing (CAM) (US Site) uses the 3D CAD model for computer numerical control (CNC) programming, which automates the movements of manufacturing machinery. The convergence of CAD and CAM allows CNC programming to take place using the same software as CAD, with the advantage that changes to the CAD model automatically update CAM toolpaths.

 

After components are made, CAD data and CAM data are used together for computer-aided inspection (CAI) and quality control. The manufactured component is compared to the CAD model using metrology devices to assess compliance with the specified tolerances and surface finishes.
