线切割加工是精密加工的一种，其使用范围正在迅速扩大，切割液切割过程中必不可少的，其用量也在迅速增加。本论文配制了针对单一金属的水基切割液，并对切割工艺进行模拟。 本论文通过正交试验方法，以基本配方为出发点，研究了切割液各组分的电导率对切割速率，切割质量的影响。确定了基本配方中各组分对电导率影响的主次关系为：三乙醇胺>正丁醇>乙二胺四醋酸(EDTA)>十二烷基硫酸钠>聚乙烯醇(PVA)>蔗糖>聚乙二醇(PEG-400)>烷基酚聚氧乙烯醚（OP-10）。通过调整对电导率影响最大的因素三乙醇胺，研究电导率对切割速率与切割表面粗糙的影响趋势，并对这种趋势进行线性拟合，确定最佳的拟合曲线，再依据曲线上的点，上切割机床验证拟合曲线的拟合偏差，确定了最佳的切割工艺曲线。 论文研究了基础配方各组份对运动粘度影响的关系为：OP-10>三乙醇胺.>PVA>洗涤剂>PEG-400>蔗糖>正丁醇>EDTA。通过调整对运动粘度影响最大的因素OP-10，确定了运动粘度对切割效率与表面粗糙度的影响趋势。模拟了OP-10对切割速率与切割表面粗糙率影响曲线，并验证了曲线的影响偏差。 由于三乙醇胺影响切割液的电导率与运动粘度，而OP-10对运动粘度影响较大，对电导率几乎不影响，可以先通过三乙醇胺调整电导率，再通过OP-10调整切割液的运动粘度，以达到期望的切割效果。 由于水基的切割液防锈性能较差，论文通过向切割液中加入自制缓蚀剂，来改善切割液的防锈性能，经过测试，缓蚀剂的防锈性能使切割液的防锈性能得到提高。

Wire cutting is one kind of precision processing, and its end-use is increasingly enlarge. The cutting fluid is an essential part in the processing of cutting. At the same time the amount of it increases rapidly. The preparation of water-based cutting fluid for a single metal was studied and the cutting technics was also modeled in this paper. In this paper, the effect of conductivity of the composites in cutting fluid on rate and quality of cutting technics based on the basic recipe by using the orthogonal test method was researched. The basic components of the cutting fluid in the formula determine the primary and secondary of the conductivity was: triethanolamine> normal butanol> ethylenediamin etetraacetic acid(EDTA)> sodium dodecyl sulfate > adhesive(PVA)> sucrose >polyglycol -400(PEG-400)>polyoxyetylated alkylphenol(OP-10). Through the adjustment of triethanolamine which is the most affected factor of rate and the impact of the cutting surface roughness. Make the linear trend and determine the best fitting curve and then based on a point on the curve to chek the fitting curve’s deviation by cutting machine. Finally fix the best cutting technology curve. The relationship of basic components in the formula and kinematic viscosity was studied in this paper:OP-10>triethanolamine> PVA> detergent>PEG-400>sucrose> normal butanol butanol>EDTA. By the amount of OP-10 as is the greatest impact on kinematic viscosity to sure kinematic viscosity effects on the trend of cutting efficiency and surface roughness. OP-10 was modeled to describe the curve of cutting speed and cutting surface and verify the bias of the curve. Triethanolamine could effect the conductivity and kinematic viscosity of cutting fluid, but OP-10 had greater impact on viscosity which almost hardly effect on the conductivity. So the conductivity was adjusted by adjusting triethanolamine following by adjusting kinematic viscosity through regulating the amount of OP-10. Since the poor anti-rustiness properties of water-based cutting fluid. The anti-rustiness properties was improved by adding corrosion inhibitor of self-making to cutting fluid. The result is that, the anti-rustiness properties of cutting fluid was enhanced by using corrosion inhibitor.
