“…14 geometrically identical blade molds were manufactured with 14 jerk setting clusters (Table 2) and subjected to inspection. From research [7], it is known that the path length affects machining performance. Without loss of generality, the mold was separated into four zones (Fig.…”

“…The engineer is responsible for selecting tools, feedrates, and speeds to generate the tool paths according to the process planning strategy for the kinematic machining operation [5]. The dynamic accuracy of machine tools is determined by the feed-axis acceleration required to produce precise movement between the workpiece and tool [6,7]. Fig.…”

“…1. Product development flow and manufacturing process chain diagram [7] The purpose of free-form surface machining is to perform the cutting of complex shapes to a given level of quality and to meet that level of quality while minimizing machining time, particularly in the aerospace and automobile industry [8,9]. There is literature focusing on speed optimization for machining, and there it is pointed out that jerk settings have a significant impact on machining time as well as the quality of the machining, especially for multi-axis machining applications [10,11].…”

There is an urgent demand for free form products in industry at the present time because of their superior appearance and the wide variety of functions they perform. Five-axis high-speed CNC machining technology has developed to satisfy this demand, but further improvement in surface quality metric inspection technology is the big challenge it now faces. In this study, the effects of jerk on the performance of five-axis synchronous high-speed CNC ball nose end mills on a freeform turbine mold were investigated. The relationships of characteristics of the images of 14 jerk-cluster finished workpieces with different jerk setting values were established, allowing surface texture features to be analyzed and surface roughness predicted. In addition, machine learning methods were integrated with the surface feature analysis to construct a virtual machining module that acts as a performance prediction system, merging the virtual machine tool functions, surface texture processor and AI roughness prediction processor. Using the geometric information of the workpiece, cutting parameters and machine tool parameters as inputs, product performance metrics combining surface roughness and machining time can be predicted as outputs of the system. The integrated system provides users with a way to evaluate manufacturing performance before performing actual operations and to reduce test time for cutting parameter development. The model is suitable for complex surface finishes as well as for the production of small batches with high parametric variance. In addition, the partial set of image processing and roughness prediction modules can be used alone as an effective intelligent surface quality inspection system.

Rapid changes in forces and the resulting changes in acceleration, jerk and higher order derivatives can have undesired consequences beyond the effect of the forces themselves. Jerk can cause injuries in humans and racing animals and induce fatigue cracks in metals and other materials, which may ultimately lead to structure failures. This is a reason that it is used within standards for limits states. Examples of standards which use jerk include amusement rides and lifts. Despite its use in standards and many science and engineering applications, jerk is rarely discussed in university science and engineering textbooks and it remains a relatively unfamiliar concept even in engineering. This paper presents a literature review of the jerk and higher derivatives of displacement, from terminology and historical background to standards, measurements and current applications.
