General CNC milling machine for special transformation in the middle and low numerical control system of internal control software does not change under the premise of achieving the original system does not have the linear movement and rotary movement of the operating linkage function. The numerical control system of linear movement into rotary movement of the operation, and expansion of two straight line linkage CNC system functions, cleverly converted to a straight line movement control of a rotary movement of the linkage, thereby achieving the surface of the cylinder rotating cam track surface CNC machining. CNC Milling through the difficult parts of the application examples to explain the design principles of transformation CNC milling machine, design approach,As well as the design parameters in the programming of data conversion. And data conversion processing errors resulting from the measures and the elimination of error analysis.

The purpose of this study was to determine the effect of feed rate and depth of cut on the surface roughness of Al-Mg aluminum using a DIY CNC Milling Machine and Krisbow Universal Milling Machine as a comparison. The open-loop control system is a control system used in the design of DIY CNC Milling machines. A PC with Mach3 software is used as a PC Based Direct Digital Controller to control the system. In this study, the feed rate variation 24 mm/minute and 42 mm/minute and depth of cut 0.25 mm, 0.5 mm, and 0.75 mm were used. After the face milling process, the surface roughness test was carried out using the Mitoyo Surface Roughness Tester to determine the level of surface roughness of the machining results the DIY Milling Machine and Krisbow Universal Milling Machine as a comparison. The results showed that as the feed rate and depth of cut increased, the surface roughness values of both tools increased.

Open Control

Open control is a well known term in the field of machine control. This paper presents a framework of STandard for the Exchange of Product Data-compliant Numerical Control (STEP-NC) based open control system for Computer Numeric Control (CNC) milling machine. Real time control, high efficiency and low cost have been the main focus of proposed open control system. A method that develops open control system is composed of hardware and software platforms. Proposed open control system helps in to improves the quality of machining, increase productivity, saves times, avoid machine accidents, increase tool life and enables monitoring/inspection/control system for various machining processes and parameters online/offline.

This research proposes a new application of 3-axis CNC milling machine for polishing the 60 HRC hardness steels. The rotary polishing tools are designed by refer to the end-mill ball nose’s design. The diamond powder are coated in rotary polishing tools by resinoid bonding method and concentrated in 4.4 karat/cm2. The Zig-milling tool paths are used to polish the hardness steel. After polishing, the confocal laser scanning microscope is used to analyze the arithmetic mean surface roughness of the hardness steels. The L12 orthogonal array of the Taguchi’s method is selected to conduct the matrix experiment to determine the optimal polishing process parameters. The diamond grit size and cutting speed of the rotary polishing tools, feed rate and step over of the tool path, the depth of polishing process penetration, and polishing time are used to study. The combination of the optimal level for each factor of the hardness steel polishing process are used to study again in the confirmation experiment. The predicted signal to noise ratio of smaller - the better under optimal condition are calculated by using the data from the experiment. The combination of the optimal level for each factor are used to study again in the confirmation experiment and the result show that polishing time was a dominant parameter for the surface roughness and the next was depth of penetration. The response surface design is then used to build the relationship between the input parameters and output responses. The experimental results show that the integrated approach does indeed find the optimal parameters that result in very good output responses in the rotary polishing tools polished hardness mould steel using CNC milling machine. The mean surface roughness of hardness steel polishing process is improved by the diamond rotary tools with the 3-axis CNC milling machine.
