The path to precise motion control

Accurate motion controllers must be matched with the right hardware to get the most precision from machine tools. Precise electronic motion controllers are certainly important in today’s advanced manufacturing environment. But to get the most out of the controllers, companies need mechanical systems that can take full advantage of their instructions. After all, linear-motion hardware executes the motion. Engineers should be aware of a few issues to get the most performance out of their machines. Precise motion calls for rightsized components to handle the load. Axial or torsional loading, for example, often requires wider or heavier-duty components than simple radial loading. But remember, you’re building a system, not just buying and assembling a collection of linear-motion components. For example, a frame design that’s too light will affect precision more than any guide component’s specified accuracy. And you also don’t want to overpay for heavy-duty components simply because you’re compensating for other weaknesses in the system. In addition, it’s important to consider other design criteria,
