Abstract As a new gear processing technology, gear slicing technology has the characteristics of high efficiency, high precision and environmental protection. In this paper, the slicing process with equal-rake angle arc-tooth slice tool (ERA-ATST) is taken as the research object. Considering the particularity of the slicing process, a theoretical calculation method of tool and chip temperature is proposed. By analyzing the characteristics of the slicing process with ERA-ATST, a cutter tooth of the ERA-ATST is divided into several sections along the cutting edge, which are called micro-section tooth. For each of the micro-section tooth, the slicing process is simplified and equivalent to oblique cutting process. Comprehensively considering the influence of cutting speed, chip force and tool-chip contacting characteristics in slicing process, a temperature calculation model is established based on the generation mechanism of slicing heat. The tool and chip temperature is derived by averaging the results of several micro-section teeth. With the established model, an inner arc-spur gear slicing with the ERA-ATST is used as an example to calculate the temperature on the chip and rake face. The gear slicing test is carried out on the slicing machine tool. The measured chip temperature and rake face temperature are compared with the corresponding calculation results to verify the temperature calculation model. The proposed temperature calculation method provides a theoretical basis for the analysis and control of slicing heat in the gear slicing process.

等前角圆弧齿切片刀具切片过程刀具与切屑温度计算

摘要 齿轮切片技术作为一种新型齿轮加工技术，具有高效、高精度、环保等特点。本文以等前角弧齿切片工具（ERA-ATST）的切片工艺为研究对象。考虑到切片工艺的特殊性，提出了刀具和切屑温度的理论计算方法。通过分析ERA-ATST切片过程的特点，将ERA-ATST的刀齿沿切削刃分成若干段，称为微断面齿。对于每个微断面齿，切片过程被简化，相当于斜切过程。综合考虑切片过程中切削速度、切屑力和刀具与切屑接触特性的影响，建立了基于切片热产生机理的温度计算模型。刀具和切屑温度是通过平均几个微截面齿的结果得出的。以建立的模型为例，利用ERA-ATST对内圆弧正齿轮进行切片，计算切屑和前刀面温度。齿轮切片试验在切片机床上进行。将测得的切屑温度和前刀面温度与相应的计算结果进行比较，验证温度计算模型。提出的温度计算方法为齿轮切片过程中切片热的分析和控制提供了理论依据。刀具和切屑温度是通过平均几个微截面齿的结果得出的。以建立的模型为例，利用ERA-ATST对内圆弧正齿轮进行切片，计算切屑和前刀面温度。齿轮切片试验在切片机床上进行。将测得的切屑温度和前刀面温度与相应的计算结果进行比较，验证温度计算模型。提出的温度计算方法为齿轮切片过程中切片热的分析和控制提供了理论依据。刀具和切屑温度是通过平均几个微截面齿的结果得出的。以建立的模型为例，利用ERA-ATST对内圆弧正齿轮进行切片，计算切屑和前刀面温度。齿轮切片试验在切片机床上进行。将测得的切屑温度和前刀面温度与相应的计算结果进行比较，验证温度计算模型。提出的温度计算方法为齿轮切片过程中切片热的分析和控制提供了理论依据。齿轮切片试验在切片机床上进行。将测得的切屑温度和前刀面温度与相应的计算结果进行比较，验证温度计算模型。提出的温度计算方法为齿轮切片过程中切片热的分析和控制提供了理论依据。齿轮切片试验在切片机床上进行。将测得的切屑温度和前刀面温度与相应的计算结果进行比较，验证温度计算模型。提出的温度计算方法为齿轮切片过程中切片热的分析和控制提供了理论依据。
