Work is similar to that of a machinist, but more specialized. Formal apprenticeship, including classroom instruction. Apprenticeship periods are usually 3-4 years or more. No college training needed, but keen competition for apprenticeship.
Some programs require math through algebra and geometry.
The employment outlook is described as mixed. Increased automation and imports of machine products is changing tool-making processes. Numerically controlled machining work requires fewer special tools, jigs and fixtures, but the tooling and fixturing for this automated machinery is more complex. Many of those currently employed are approaching retirement age, and replacement requirements are expected to result in improving employment opportunities for qualified job seekers. Union members usually earn more.
