本文介绍了为工程制造提供工件材料可加工性信息的基本概念、一般步骤和不同方法。本文的重点是分析目前该领域最活跃的研究领域——短时可加工性试验——一种恒定进给力法。本文详细介绍了位移数据采集的计算机数据采集系统。使用最小二乘法，作者从数学上描述了进给速度与时间的函数关系。初始进给速度和刀具减速度的绝对值是主要的可加工性指标。为了开发统一的可加工性测试方法，有必要进行一系列系统的测试。

THE PAPER PRESENTS THE ESSENTIAL CONCEPTS, GENERAL PROCEDURES AND DIFFERENT METHODS USED TO PROVIDE THE ENGINEERING MANUFACTURING WITH THE INFORMATION OF MACHINABILITY OF WORKPIECE MATERIALS. THE EMPHASIS OF THIS PAPER IS TO ANALYZE THE SHORT TIME MACHINABILITY TEST--A CONSTANT FEED FORCE METHOD, CURRENTLY THE MOST ACTIVE AREAS OF RESEARCH IN THE FIELD. A COMPUTER DATA ACQUISITION SYSTEM FOR SAMPLING DATA OF DISPLACEMENT IS PRESENTED WITH DETAILS AND IN GRAPH. USING THE LEAST SQUARES TECHNIQUE, THE AUTHOR DESCRIBES THE FEED RATE AS A FUNCTION OF TIME MATHEMATICALLY. THE INITIAL FEED RATE AND THE ABSOLUTE VALUE OF TOOL DECELERATION ARE PRIMARY MACHINABILITY MEASURES. SUCH A SET OF SYSTEMATICALLY PERFORMED TESTS WOULD BE NECESSARY TO DEVELOP UNIFORM TEST METHOD OF MACHINABILITY.
