Model machinists create models of components for product development, often using CAD and CNC equipment. They work with design teams to develop prototypes and may work independently or as part of a team. Special skills may be required for certain projects, such as security clearance or familiarity with harsh environments.
A model machinist makes models of components for product development. This can include scale models and complete versions including moving parts. Companies that design and repair machined parts can use model machinists in full-time and part-time positions to meet their needs. It is also possible to work independently and complete projects under contract upon request from various companies.
To work in this field, it is usually necessary to have extensive experience as a mechanic. Some components may need to be manufactured by hand, especially in the early stages of the project, which requires experience and skill. In addition, it is often necessary to become familiar with computer-aided design (CAD) and computer numerical control (CNC) equipment. The model machinist needs to be able to read technical drawings, produce parts to specification, and participate in the development of plans for mass production.
As a company moves a product into development and engineers begin to produce detailed drawings, the model mechanic meets with the design team to discuss specifications. They can talk about shape, size, building materials and other parameters. With this information in hand, the mechanic can develop a working model or prototype. In the early stages, designers may want to see what the product will look like, without working components or a full scale size. As the project progresses, they may need more working prototypes from the model mechanic.
In some cases, a team of people can work on making models. The model machinist can make some parts of the component and participate in activities such as programming equipment to reproduce CAD schematics in physical materials. Other team members can produce in the development of additional parts. This can be necessary on complex projects, such as building prototype cars, where a single technician may not have the necessary skills to produce an entire working model.
Special skills may be required for some model machinists. Some work on confidential or classified material; in that case, they may need to pass security checks and sign non-disclosure agreements. Others may be involved in projects that require familiarity with harsh environments, such as space or oil fields, so they can create components that work effectively in those locations. Travel to test some components may be necessary if a facility does not have the space to do so. It can also be important to keep up with developments in the field through trade publications, conferences and other resources.
