数控铣床在屑状标准样品研制中的应用

Application of numerical control milling machine in the development of standard sample

文章以纯铁棒材为研究对象，利用MLF-SX850立式数控铣床对纯铁棒状材料进行铣屑试验，得出适宜的走刀速度、主轴转速和进给量。实验结果表明，主轴转速为200r／min、走刀速度为100mm／min且进给量保持在1mm时得到的屑状产品形貌接近市售产品，成分波动性小，对今后研制其他材质的屑状标准样品具有指导意义。

The iron bars as the research object, using MLF-SX850 CNC vertical milling machine to milling experiments and we appropriate cutting speed, spindle speed and feed rate. The experimental results show the best parameter that the spindle speed is 200 r/min, walking speed of the tool is 100mm/min and feed rate maintained at lmm.The morphology of the products close to the commercially available products, without fluctuation in the components. It has guiding significance in the further development of other materials standard sample.
