The Manufacturing Equipment Support Model Based on the Manufacturing Equipment Role

This work aims to investigate the manufacturing equipment support model for the purpose of improving the efficiency and quality of manufacturing. First, the concept of manufacturing capacity is defined, and the re- lationship between practical and expected manufacturing capacity is described. Then the concept of role is intro- duced and the manufacturing equipment role is defined in detail. Based on the analysis of manufacturing capacity and manufacturing equipment role, the three-stage manufacturing equipment support model is proposed. With this model, the manufacturing task can be decomposed into several manufacturing equipment roles, and the ex- pended manufacturing capacity involved in the manufacturing equipment role can be matched with the practical manufacturing capacity of the enterprise. The measures are discussed depending on different matching degrees.

Robotized manufacturing equipment:A review from the perspective of mechanism topology

In recent years,robots have been extensively applied in the establishment of intelligent manufacturing systems.Many robotized manufacturing equipment have been developed,some of which have gained successful applications.A mechanism is the skeleton of a machine that transfers motion and energy.The topology of a mechanism is an important gene that determines the function and performance of a machine.Although several reviews have focused on robotized manufacturing,an up-to-date review of robotized manufacturing equipment from the perspective of mechanism topology is lacking.This motivated us to present a survey about existing robotics structures used in manufacturing equipment.Relevant studies are classified into three types:serial robot-based manufacturing equipment,parallel kinematic machines,and hybrid robot-based manufacturing equipment.The features and performance behaviour of these equipments,as determined by their mechanism topology,are analyzed.In particular,the influences of joint numbers,rotational axes of output motion,actuation schemes,and topological symmetry on equipment performance are discussed to provide insight into the new development of robotized manufacturing equipment,as well as future research directions on this topic.

Research on Cutting Trajectory of Electroplated Diamond Wire Saw

The cutting process of electroplated diamond wire saw was researched on the basis of impulse and vibration machining theories. The different contact states in the cutting process were analyzed by using the finite element method. It shows that the cutting stress is uniformly distributed along the direction of the workpiece width in the steady state. A mathematical equation of sawing trajectory was established by using the superposition principle and the cutting experiment of wire saw to calculate the cutting trajectory. The comparison of the theoretical trajectory with the calculated one indicates that the error is less than 15%. The research results provide a theoretic basis for optimization of the saw's cutting process parameters.

Contract Manufacturer's Market Entry and Its Impact under Asymmetric Customer Loyalty

We study a supply chain in which an original equipment manufacturer(OEM)outsources manufacturing functions to a contract manufacturer(CM)for cost saving.In addition to accepting the OEM's order,the CM can develop self-branded products and enter the end-market.Because of the OEM's well-known brand and long-term good reputation,we take the asymmetric customer loyalty into consideration-a fraction of customers are loyal customers(LCs)who only consider buying the product from the OEM,while other customers in the market are non-loyal customers(NCs)who might switch to purchasing the CM7s product because of the lower selling price.We explore whether the CM will enter the end-market and if so,what is the impact of the market entry on the OEM and the entire supply chain.Counterintuitively,we find that there will be no market entry when the CM is relatively strong,i.e.,the CM is able to provide self-branded products with relatively high acceptance and the CM has a relatively large bargaining power.In addition,when the NC segment is an important profit source for the OEM,i.e.,the NCs7 market size is relatively large and their willingness-to-pay is relatively high,the market entry will not occur,either.The OEM's profit is always hurt by the CM's market entry unless the OEM always only sells the product to the LCs,while the supply chain sometimes can get benefit.Through numerical simulations,we reveal the relationships between the profit change of different parties and the key parameters,such as the relative willingness-to-pay and market sizes of two types of customers,the CMrs bargaining power and the acceptance of the CMrs product,when the market entry becomes an available option for the CM.The impact of production cost difference on the market entry decision and profit changes is also analyzed in the extension when producing the OEM's product is more costly for the CM than producing the self-branded product.

A 2-dimensional impact driven precise actuator using piezoelectric bimorphs

A new precise actuator is proposed,which is ac-tuated by the impact force of an end-loaded piezoelectric bimorph cantilever,and bears two degrees of freedom for translation and rotation.The dynamic characteristics of the piezoelectric bimorph were analyzed by FEM,and are fur-ther proved by experimental tests.A new control system for the actuator was put forward and tested,which is called the fixed-frequency with adjustable voltage.In addition,the actuator’s performance of translation and rotation were both measured.The results demonstrate that the actuator is char-acterized by a simple structure,large movement range,strong driving ability and high positioning resolution.Its cost is estimated at only 1%of the traditional impact actuators.
