Abstract:

The development of unmanned machining systems has been a recent focus of manufacturing research. Computer Numerical Control (CNC) units, which monitor and control many tightly coupled machining tasks, are inseparable parts of the unmanned manufacturing system. This thesis addresses the detailed design and analysis of a modular CNC system for a milling machine. The feed drive control system of the machine tool is thoroughly studied. The mathematical model for the feed drive control system, which consists of a motion controller, power amplifiers and DC-servo motors, is developed and experiment

Abstract:

In this study, a three-axes PC numerical control system for industrial applications has been developed. With this system, fast and cheap prototyping of designed objects can be realized. The system consists of software and a hardware which includes an XYZ positioning table and three step motors controlling this table. A proper drive circuit for the stepper motors is utilized. The software digitizes two dimensional drawings of three dimensional objects and generates the control signals for the XYZ positioning table. The software is developed under Microsoft Studio Visual Basic 6.0 environment re

Abstract:

Electrical Discharge Machining (EDM) is a non-contact manufacturing process in which material is removed from a metal workpiece by high frequency electrical pulses produced between an electrode and the workpiece. EDM machines are usually stand-alone devices, and are quite expensive. The objective of this research was to integrate an EDM machine and an existing reconfigurable CNC machine tool, using a modular approach, to enable conventional milling and EDM to be conducted in a co-ordinated fashion on the same machine tool.

Abstract:

Prototyping is an essential step in the manufacture of many objects, both consumer and industrial. A fundamental step in this process is the definition of the three dimensional form of the object shape; for example, a designer's models created in clay or wood. A three dimensional vision system (range sensor) offers the advantage of speed in defining shapes compared to traditional tactile sensing. In this thesis, the viability of using range sensors is demonstrated by developing a rapid prototyping system comprised of a laser-based range sensor and software that creates a computer model of the

When the drive transmits power to the load for processing, the response will be different during power transmission, and it will be affected by the controller when performing position control. When the two errors are superimposed, the load position response of the machine tool will be different. Therefore, in this study, the position controller parameters are designed based on the theme of two-axis corner motion and implemented in a dual-quality experime

It can machine a workpiece in one setup and eliminate errors that can be produced by moving the workpiece between turning and milling machines. Since the mill-turn machine has a complex configuration in which linear and rotary movements are nonorthogonal, generating the part program manually is almost impossible.

Owing to the fact that multi-axis NC data can only be applied to the specified machine tool configuration and various combinations may be synthesized to multi-axis machine tool configuration, the portability of the NC data is inevitably reduced. The current domestic aerospace industries are almost the subcontracts. The NC data f
