Työstömäärä

Työstömäärä refers to the amount of material removed from a workpiece during a machining operation. It is a crucial factor in determining the efficiency, cost, and quality of a manufacturing process. Understanding and controlling työstömäärä is essential for achieving desired dimensions, surface finishes, and overall part integrity.

The työstömäärä is typically calculated by subtracting the final dimensions of the workpiece from its initial dimensions. For example, if a metal rod is initially 20mm in diameter and is machined to 18mm, the työstömäärä is 2mm. This removal of material can be achieved through various machining processes such as turning, milling, drilling, and grinding.

Factors influencing the optimal työstömäärä include the material being machined, the type of cutting tool used, the cutting speed, feed rate, and depth of cut. Excessive työstömäärä can lead to increased tool wear, higher energy consumption, and potential workpiece damage. Conversely, insufficient työstömäärä may result in incomplete material removal or failure to achieve the required tolerances. Therefore, careful consideration and optimization of työstömäärä are vital for efficient and successful manufacturing.
