Feed Rate Optimization

Aiming at the problem of lower efficiency of complex surface machining with constant feed-rate, a method for feed-rate optimization based on S curve acceleration and deceleration control of piecewise tool path is researched. With constraints of kinematic characters of machine tool and geometric characters of tool path, tool path segments are obtained by curvature threshold method, and feed-rates are planned in these segments, then feed-rate transition of adjacent segments is processed by the method of S curve acceleration and deceleration control. Experimental result indicates that the proposed method is feasible and effective.

Feed Rate Optimization

Optimization is an important way to improve the machining quality, efficiency, security and safety. In traditional way, feed rate is specified off-line in CAM system by process planner, which leads to the low machining efficiency. In the paper feed rate optimization technique based on generalized predictive control is researched. The open architecture is adopted to develop an adaptive controller, where the feed rate can be real-time adjusted in CNC system according to the measured cutting force. An open CNC controller with the function of feed rate optimization is implemented, which consists of a series of software modules. Simulation experiment has been finished to prove the proposed method.

Feed Rate Optimization

The work aims at the optimization of the output feed rate of a Stationary Hook Hopper Feeder so that the best possible set of parameters affecting it can be selected to get the desired output. For this purpose the effect of various parameters on the feeder output is studied. To facilitate the study and detailed analysis, a statistical model is constructed which is used to predict and optimize the performance of the system. Efficient feed rate optimization determines the input variable settings to adjust the feed rate of the feeder according to the consumption of the parts in the next phase of production. The Stationary Hook Hopper Feeder, whose performance is to be studied, consists of a rotating circular plate and a guiding hook fixed at the centre and running up to the periphery of the plate. As the plate rotates, the parts follow the trajectory of the hook, orient themselves and then eventually are delivered through the delivery chute, tangentially to the plate. The factors influencing the feeder’s performance include the speed of rotation of the disc, the population of the parts in the hopper and the size of parts to be fed. A series of experiments is performed on the three process parameters to investigate their effect on the feed rate. To study the interaction among the factors a full 23 factorial experiment approach has been adopted using the two basic principles of experimental design-replication and randomization. The process model was formulated based on Analysis of variance (ANOVA) using Minitab® statistical package. The outcome is represented graphically and in the form of empirical model which defines the performance characteristics of the Stationary Hook Hopper Feeder.

Acceleration Profile

In order to prevent machine tool feed slide system from transient vibrations during operation, machine tool designers usually adopt some typical design solutions; box-in-box typed feed slides, optimizing moving body for minimum weight and dynamic compliance, and so on. Despite all efforts for optimizing design, a feed drive system may experience severe transient vibrations during high-speed operation if its feed-rate control is not suitable. A rough feed-rate curve having discontinuity in its acceleration profile causes serious vibrations in the feed slides system. This paper presents a feed-rate optimization of a ball screw driven machine tool feed slide system for its minimum vibrations. A ball screw feed drive system was mathematically modeled as a 6-degree-of-freedom lumped parameter model. Then, a feed-rate optimization of the system was carried out for minimum vibrations. The main idea of the feed-rate optimization is to find out the most appropriate smooth acceleration profile having jerk continuity. A genetic algorithm, G.A., was used in this feed rate optimization.
