Työstökierros

Työstökierros refers to a machining process where a workpiece undergoes a series of cutting operations. This sequence is designed to gradually shape the material towards its final intended form. Each pass or step in the työstökierros removes a specific amount of material, progressing from roughing cuts to semi-finishing and finally to finishing cuts. The order of these operations is crucial, as roughing removes large quantities of material quickly, while finishing operations achieve precise dimensions and surface finish.

The concept of a työstökierros is applicable across various machining methods, including turning, milling, drilling, and grinding. For instance, in turning, a työstökierros might involve facing the end of a shaft, then turning its diameter to a rough size, followed by a finer cut to achieve the final diameter and a smooth surface. In milling, it could involve removing bulk material with a coarse-toothed cutter, then using a finer cutter to achieve the desired shape and tolerances.

The effectiveness of a työstökierros is influenced by factors such as the type of machine tool, the cutting tools used, the material being machined, and the desired accuracy. Proper planning of the työstökierros is essential for efficient production, tool life, and the quality of the finished part. It minimizes stress on the workpiece and tooling, prevents excessive heat buildup, and ensures that dimensional tolerances are met.
