Abstract:

The aim of this paper overviews about to find out the errors that come from three axis CNC vertical milling machine. The errors come from, the CNC milling machine can be modelled into mathematical models and later on these error models will be used to analyse the errors in the measured data. Many errors from CNC machine tools have given significant effects toward the accuracy and repeatability of manufacturing process. There are two error sources come from CNC machine tools such as tool deflection and thermal distortions of machine tool structure. These errors later on will contribute to result in the geometrical deviations of moving axis in CNC vertical milling machine. Geometrical deviations of moving axis such as linear positioning errors, roll, pitch and yaw can be designated as volumetric errors in three axis machine tool. Geometrical deviations of moving axises happen at every axis in three axis CNC vertical milling machine. Geometrical deviations of moving axises in linear and angular movement has the amount of errors up to twenty one errors. Moreover, this geometrical errors play the major role in the total amount of errors and for that particular reason extra attention towards the geometrical deviation errors will be needed along machining process. Each of geometrical error of three axes vertical machining center is modeled using a homogeneous transformation matrix (HTM). The developed mathematical model is used to calculate geometrical errors at each axis and to predict the resultant error vector at the interface of machine tool and workpiece for error compensation.

Abstract:

In milling operation, Computer Numerical Control (CNC) milling machine has been recognized as one of effective solutions for high productivity, efficiency, and precision. However, the existing CNC milling machine has contributed to ergonomics-related problems such as awkward working posture. The aim of this study is to redesign the existing CNC milling machine by considering working posture of the machinist. This study performed questionnaire survey to determine ergonomics feature requirements from the machinist. The requirements of the machinist are then translated using Quality Function Deployment (QFD) to obtain technical specifications of new design CNC milling machine. The working posture of machinist during operating the existing CNC milling machine and the redesigned CNC milling machine was assessed using Rapid Upper Limb Assessment (RULA). Based on the analysis, the redesigned CNC milling machine has improved the working posture as shown by low score of RULA. This study concluded that by considering the ergonomics feature requirements to the design of CNC milling machine enabled the machinists to perform milling operation in safe working posture. This study suggests that environmental factors should be considered in the future research works.

Abstract:

This workpiece process is: to find out how to transfer images from Auto CAD software to the Q plus CELL Milling Cnc software, and to find out how to transfer programs from the CNC Milling QELL KELLER software to the TU 3A CNC milling machine. The making of this workpiece uses three main media, namely Auto CAD 2000 software, CNC Milling KELLER Q plus software, and TU 3A CNC milling machine. The process of making the workpiece starts from making the workpiece design in Auto CAD software which is then stored on the CDR via DFX data. The design of the workpiece contained in the CDR is then transferred to CNC Millling KELLER Q plus software via Geometry. in Geometry, the design of the workpiece is dimensioned. Completed from the Geometry the workpiece design is included in the Work plan to be processed so that it can be simulated to move to a CNC program to convert the graphical language into a numeric language so that it can be read by a CNC machine. The programming results from the CNC KELLER Q plus software are then recorded to be executed on the CNC TU 3A milling machine to obtain the workpiece in accordance with the design in AutoCAD. Programming results from CNC Milling KELLER Q plus software cannot be directly used on the TU 3A milling machine (EMCO), because the programming language used is different. Programming language in CNC Milling KELLER Q plus software uses the DIN 66025 standard, while the CNC TU 3A (EMCO) milling machine uses ISO standards, so it needs to be converted first.

Abstract:

CNC machine tools are currently predominating in the machine-building industry. Generally, these machine tools are equipped with control systems supplied by the world's leading manufacturers, such as Siemens, Fanuc or HeidenHein, and are very expensive. In parallel, many cheap amateur and semi-professional CNC machine tool solutions are being developed. Below, a CNC milling machine of welded construction is described, which is intended to be, at the same time, a test stand. The design of the milling machine is based on steel closed sections of a large cross-section and a big wall thickness. This has allowed a rigid frame structure to be obtained. To obtain high displacement accuracy, high-accuracy profiled rail slideways have been used, along which pre-stressed linear ball bearings move. The machine tool has been furnished with a fourth numerically controlled axis, which is demountable.

Abstract:

The manufacturing technology has developed rapidly, especially those intended to improve the precision. Consequently, increasing precision requires greater technical capabilities in the field of measurement. A prototype of a 3-axis CNC milling machine has been designed and developed in the Research Centre for Electrical Power and Mechatronics, Indonesian Institute of Sciences (RCEPM-LIPI). The CNC milling machine is driven by a 0.4 kW servo motor with a spindle rotation of 12,000 rpm. This study aims to measure the precision of the CNC milling machine by carrying out the measurement process. It is expected that the CNC milling machine will be able toperform in an optimum precision during the manufacturing process. Accuracy level testing is done by measuring the deviations on the three axes namely X-axis, Y-axis, and Z-axis, as well as the flatness using a dial indicator and parallel plates. The measurement results show the deviation on the X-axis by 0.033 mm, the Y-axis by 0.102 mm, the Z-axis by 0.063 mm, and the flatness of the table by 0.096 mm, respectively. It is confirmed that the deviation value is within the tolerance standard limits set by ISO 2768 standard. However, the calibration is required for this CNC milling machine to achieve more accurate precision. Furthermore, the design improvement of CNC milling machine and the application of information technology in accordance with Industry 4.0 concept will enhance the precision and realibility.

Full text

Abstract:

There is a requirement for improved three-dimensional surface characterisation and reduced tool wear when modern computer numerical control (CNC) machine tools are operating at high cutting velocities, spindle speeds and feed rates. For large depths of cut and large material removal rates, there is a tendency for machines to chatter caused by self-excited vibration in the machine tools leading to precision errors, poor surface finish quality, tool wear and possible machine damage. This study illustrates a method for improving machine tool performance by understanding and adaptively controlling the machine structural vibration. The first step taken is to measure and interpret machine tool vibration and produce a structural model. As a consequence, appropriate sensors need to be selected and/or designed and then integrated to measure all self-excited vibrations. The vibrations of the machine under investigation need to be clearly understood by analysis of sensor signals and surface finish measurement. The active vibration control system has been implemented on a CNC machine tool and validated under controlled conditions by compensating for machine tool vibrations on time-varying multi-point cutting operations for a vertical milling machine. The design of the adaptive control system using modelling, filtering, active vibration platform and sensor feedback techniques has been demonstrated to be successful.

Abstract:

The marriage of computer, electronic technology and traditional machining disciplines has given birth to revolutionary new disciplines, Mechatronics. Therefore Mechatronics requires mechanical, electronic and computer knowledge together. The main aim of this article is to present the mechatronics approach for desk-top CNC milling machine design. Construction of computer controlled (CNC) Machine differs greatly from that of conventional machine tools. This difference arises from the requirement of higher performance levels. Machine Structure, guide ways, feed drives, spindle and spindle bearings, measuring systems, machine control unit, software and operator interface, gauging and tool monitoring should be considered as mechatronics approach. Servo motors, motor drivers and motor control unit were used in this CNC milling machine to make it flexible and easy programming. Ball screws were used to X-Y –Z axes to eliminate backlash of the slides. Non-contact home and Limit switches were used to prevent possible damages against over travels. Necessary torque and power have been calculated to select the motors by taking care of the load, ball screws, motor inertia and required cutting tools and etc. and developed CNC milling machine has been tested several times for reliable machining of machine parts.

Abstract:

AbstractThis paper presents a convenient and an easy to use manufacturing method for parts with axisymmetric geometry on CNC milling machines. The desired form of the cavities is achieved by selecting as generatrix curve any plane curve, implicitly or parametrically defined, which fulfills specific imposed by the user criteria (functional, aesthetic or other). Each machining pass is modelled as a path composed of generatrix curve segments and semicircular arcs. The surface quality is controlled by keeping the distance between successive scallops within a programmed value. Tool motion along the desired paths is generated by G-code algorithms that exploit the parametric programming technique, a powerful CNC programming tool. The effectiveness of the proposed method is verified by simulation tests for three representative curves.

Abstract:

During the technological development, some equipments remain mostly the first days design besides most of others change repeatedly. CNC Milling machines spindle design is one of these which remains mostly the same. With the existing design, in order to obtain the desired torque for metal milling process, the body of the spindle is made huge and heavy which causes the whole machine body to be constructed huge and heavy. In this study a new approach to CNC Milling Machine Spindle Design is made. The design changes the hob to be held indirectly instead of to be held directly at the lower end of the spindle. The huge spindle motor is fixed to the ceiling over the machine and a flexible steel rope is used to transfer the rotational motion. At the end of the steel rope, a planetary gearbox is fixed which is also fixed to the mobile part of the CNC construction. By this way, the required torque is obtained just at the milling process takes place and the motion transmission parts can be made light in weight like the whole construction would be made.

Abstract:

In machining operation, the cutting parameters greatly influences on the spindle vibration of a CNC wood milling machine. The paper presents the effect of the cutting parameters such as feed rate, cutting speed, and cutting depth on the vibration amplitude of the spindle when machined on CNC milling machine using Box-Hunter method of experimentation. The lowest natural frequency of this machine is 250 Hz. Experimental results have established a second-order regression equation that demonstrates the effect of three parameters such as feed rate, cutting speed, and cutting depth on the vibration amplitude of the spindle. From that base, determine the most reasonable cutting parameters when machining on CNC wood milling machines so that the spindle vibration amplitudes is minimal. In addition, The comparison results show that the spindle head vibration amplitude of the machine using the bolt joint is larger than the spindle head vibration amplitude of the machine using the weld joint.
