増材制造技术仍然存在表面质量相对较差、尺寸精度较低、零件材料致密性较低等缺点，加工出来的零件难以直接用于实际应用中，在通过增材制造方法完成零件成型后往往需要利用车削、铣削、磨削等减材制造方法进行减材制造，以达到零件所需的表面质量与尺寸精度。然而，对于结构复杂的零件表面，常因工件结构的干涉而无法实现复杂表面的减材制造，并且，增材制造与减材制造分别进行，需要重新装夹、定位，这样会影响加工精度与加工效率。因此，单一的増材制造或者单一的减材制造均无法胜任结构复杂、表面质量要求高、尺寸精度要求高的零件的快速高效生产。为了有效解决当前増材制造设备制造出的零件难以直接用于实际生产的问题，提供了一种根据CAD模型数据增减材复合制造统一建模，仿真，验证和优化，进行増材制造和减材制造的交替，进行复杂曲面零件的一次性成型制造，无需二次加工，可以有效提高复杂零件的加工效率与成型精度。
PartingAdviser introduction
Virtual Mold Design
Firstly we transform our surface plastic part model into Extended Z Map. Then we do draft analysis to detect undercut.
Secondly we explode the part into core and cavity face groups.
Our Extended Z Map is used to classify the part face into core, cavity, both direction, and undercut face groups. There is no parting line search or selection process until the next step. We don’t use the parting line to separate the core and cavity faces. Our method does not need to traverse the B-rep edge face relation map.
Thirdly we perform the parting edge and hole edge loop search on the exploded core and cavity faces groups
Kojin mould case study
QuickSeeNC first case study 1999
The High Speed Machining (HSM) is the most important technological development in precision engineering. The constant load is a very important factor in HSM. The cutter will break under uneven cutting force. The HSM requires huge tool path to realise the constant load. The milling tool path can easily exceed a half million blocks of machine code. As the feed rate is already very high, it is almost impossible to run test cutting by increasing the feed rate. Visual tool path check is difficult as the tool path overlapping with each other. It takes a long time to run traditional NC simulation software.
Comprehensive machining simulation beyond g code verification final
Modern NC simulation software can reduce design and manufacturing time by automatically simulating NC programs to verify the machined workpiece matches the design. Simulation provides an electronic model of the in-process workpiece that can be used for documentation, inspection plans, and process planning. It also detects potential machine crashes. Latest simulation software optimizes feed rates and can simulate multiple machine setups simultaneously.
Pervasive Geometry Simulation
SIMTech has patented a common data model to represent geometry, attributes, and physical states of various manufacturing processes like milling, turning, molding, and EDM. This method integrates discrete unit processes into a multi-step model for designing and verifying pervasive manufacturing processes. A second patent has been filed applying this method to mold design and verification.
Unified Geometry Modelling for Pervasive Design and Fabrication
Conventional Computer Aided Design (CAD), Computer Aided Engineering (CAE), and Computer Aided Manufacturing (CAM) employed discrete geometry models that could not be easily exchanged and effectively employed for biomech design and fabrication.
SIMTech has patented a common data model for representation of geometry, attributes, physical states and other characteristics of novel manufacturing processes. The method could be extended to integrate these discrete point unit processes into a unified geometrical model for pervasive design and verification.
Machining modelling simulation beyond nc verification
Smart machining adds intelligence to the machining operation. NC simulation could take into account the exact depth, width and angle of each cut and optimize the machining parameters based on the machining model and measured data of the part geometry.
Profiting from dynamic numerical control verification system
SIMTech developed QuickSeeNC, a numerical control (NC) machining verification system that models, simulates, verifies and optimizes NC tool paths. QuickSeeNC has been adopted by several local die and mould makers because it is fast and simple to use. It provides "What You See is What You Cut" functions to efficiently model, simulate, verify and optimize complex NC machining processes.
Virtual machining chapter manufacturing technology handbook
“Virtual machining” is a modelling process that realistically simulates the setting up and running of an actual machining operation. First, the user specifies the stock from which the part will be cut, either by entering dimensions into the software or importing a CAD model. Then, after selecting the cutting tools, the NC program (either G-code data or native CAM output) automatically simulates the motion of the tool removing material from the stock. The programmer can watch the material removal process and see details of how each cut changes the shape of the part. This eliminates having to try to imagine how cuts from the current operation will affect subsequent operations.
A virtual cnc training system
Simulation of machining process for CNC training is significant given its lower cost and risk-free nature. The drastic decrease of the cost of computer, couple with the worldwide price increase in material and machine tools meanings that virtual CNC training using computerized modelling and simulation is a cost-effective and sustainable approach to technical and professional education in manufacturing applications. The virtual CNC training system is developed for simulation of multiple machining processes. It is particularly important in the training of knowledge-intensive high speed and ultra precision machining. The in-process model proposed for the virtual CNC training system is presented in detail, followed by case studies of the industry training applications. Compared with conventional on-site manual training or e-learning, the virtual CNC training system greatly increases learning efficiency and effectiveness of trainees, and improves cost saving in terms of machine and material uses.
Towards smart and sustainable machining
Computer Numeric Control (CNC) revolutionized the machining technology and has been the cutting edge of digital manufacturing since 1950s. CNC machining model, simulation, verification, and optimization have been a vivid research topic of Smart Machining that automated the CNC programming (CAM) and cutting process, hence greatly increased machining productivity since 1990s. This paper traces back the history of CNC simulation, analysis the different CNC machining models, tested with application examples, and listed different CNC verification industry applications for the last 20 years. The new challenge comes from sustainable manufacturing. Towards smart and competitive sustainable machining, CNC model and simulation will be used to optimize the machining process, where the raw material could be saved through First Part Correct technology, the energy could be saved through cutting speed optimization, and used parts could be saved by remanufacturing.

Enhance Virtual Reality (VR) for advance personalized learning has been listed as the grand engineering challenge [1]. However, current VR model is not deformable to describe the shape change of manufacturing processes, such as subtractive machining or additive layer manufacturing (LM). Further more, current VR model is not precise enough to simulate the measurement of workpiece, which may go to submicron level. This paper reviewed the current industrial needs of virtual computer numerical control (CNC) training, listed the critical technology issues, traced the 20 years evolution of in-process models of CNC machining, and proposed a new solution. Based on the proposed in-process model, a virtual CNC training system has been developed and used in training courses. Comparisons with conventional on-site manual training and VR based e-learning concluded this new approach could greatly improve safety, increase learning efficiency, and save machine and material.
Quick NC simulation & verification for high speed machining
Numerical Control (NC) machining is the cutting edge of modern manufacturing technology. NC errors could break cutter edges, destroy work pieces and even damage the machine tool. In recent years, more and higher speed cutting is applied in the industry due to the advancement of machine tool technology and the demand of shorter production time. However, checking the NC codes for high speed machining is difficult due to the lack of information on material removal rate and the large size of NC blocks. In this paper, a novel high speed NC simulation method in an extended Z-map approach is presented, which offers higher simulation accuracy of the resulted geometry and with reasonable cutting load calculation. In conclusion the authors propose the pervasive manufacturing modeling and simulation for multi machining and layered manufacturing processes.
Profiting with competitive sustainable machining technology
Sustainability has found its way to machining, increasing productivity and reducing cost at the same time. By Liu Peiling, principal research engineer, SIMTech.
Manufacturing Process Simulation Based Geometrical Design for Complicated Parts
More than ever, it is critical that products are designed and manufactured right the first time. Design for Manufacturing (DFM) methodology has been recognized as one of the most effective ways to short product lifecycle time and reduce manufacturing cost. The main function of DFM in the detailed design stage is analyzing the manufacturability of the part. Various existing manufacturability evaluation methods have their limitations. In this paper, a new approach to DFM for the complicated parts is proposed. Instead of checking the manufacturability following the design, the in-process model resulting from the manufacturing process simulation is used to generate process dependent geometry surfaces at the design stage. The definition of the manufacturing process dependent geometry is given, and the methodology for creation of in-process model is presented in details.
TOWARDS A UNIFIED IN-PROCESS GEOMETRIC MODEL FOR MULTIPLE MACHINING AND Layer...
There are many fabrication processes in modern manufacturing, but current modeling and simulation tools only simulate a few unit processes based on different geometry models. To overcome the data exchange problem between different models, this paper studies various in-process geometry models together with their working systems / prototypes for traditional manufacturing processes. Novel hybrid multiple-machining and layered manufacturing processes are presented to identify critical issues. Working towards a vision of pervasive modeling and simulation, a unified Voxel-based in-process geometry model for multiple-machining and layered manufacturing simulations is proposed and discussed.
Nc verification and re processing for collaborative machining
This document discusses collaborative machining and the need for quick NC data verification and re-processing. It begins with an abstract that introduces collaborative machining and identifies verification and re-processing as critical issues. It then reviews traditional NC simulation methods like B-rep, section, and Z-map representations. The document proposes a dynamic in-process stock model using a new geometry representation and describes a system developed for quick NC verification and re-processing using OpenGL. Test results showed the system can effectively optimize machining processes in collaborative environments.

Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
