切割

An energy coupling model is built up on the front and kerf shape photographed.

结果表明，由于前沿存在多次反射，使得切割深度增加。

Kerf roughness and quality control of laser precision cutting［J］.

激光精密切割不锈刚模板割缝质量控制［J］。

The results showed that the kerf width increases with the increase of the power density, pulse frequency and pulse width; the cutting speed is increased and the cutting quality is improved with increasing the pulse frequency.

结果表明，缝宽随激光功率密度、频率以及脉宽的增加而加大；提高激光输出重复频率，不仅有利于提高加工质量，而且可以增大切割速度，提高加工效率。

They will block kerf between the seal with epoxy cement prison, and then a little way to the surface of disappearing, is almost identical with the original, if not carefully see if it is difficult to see the middle has been cut.

他们将块体间的切缝用环氧水泥封牢，再一点点地把表面抹平，几乎跟原貌相同，如果不细心查看的话，很难看出中间曾经切割过。

The fibre reinforced resin bond grinding wheel for cutting off is widely used. The traditional presses used for manufacture this type of grinding wheel in most factories at present have problems, such as laboriousness for workers, low efficiency of production, and dependance of products quality on operators' skillnes. This paper introduced a new type of press for shaping grinding wheel with six stations designed by the authors, considering the shortcoming of presses in use and the operating characteristics in manufacture of this type of grinding wheel.

概述纤维增强树脂薄片砂轮是一种低值易耗产品，在树脂砂轮中占有很大的比重，主要用于切割各种规格的型钢，在国内外都有较大的市场，随着市场竞争的加剧，对产品质量和生产效率提出了更高的要求，各生产厂家只有通过降低生产成本提高产量来挤占市场。
