Influencing the final machining accuracy and processing efficiency of the workpiece, in addition to the reasons of the CNC machine tool itself, it should also be set from reasonable processing route setting, tool selection and correct installation, reasonable cutting amount selection, programming skills, and rapid control of dimensional accuracy. Comprehensive considerations.
First, programming skills
Numerical control programming is the most basic work of numerical control processing. The pros and cons of the work piece processing program directly affect the final machining accuracy and processing efficiency of the machine tool. From the clever use of the inherent program, to reduce the cumulative error of the CNC system, the flexibility to use the main program and subroutines and other aspects.
1. Flexible use of main programs and subroutines In complex mold processing, the molds are generally processed in the form of multiple molds. If there are several identical shapes on the mold, the relationship between the main program and the subroutine should be used flexibly, and the subprograms should be called repeatedly in the main program until the machining is completed. Not only can ensure the consistency of the processing size but also can improve its processing efficiency.
2, reduce the cumulative error of the numerical control system
In general, incremental programming is used for workpieces. The previous point is used as a reference for processing. This way, the continuous execution of multiple segments of the program will inevitably produce a certain cumulative error. Therefore, when programming, absolute programming is used as far as possible so that each segment has a workpiece. The origin is used as a reference, so that the cumulative error of the CNC system can be reduced and the machining accuracy can be guaranteed.
Second, a reasonable set of processing routes
Reasonable setting of processing routes and processing sequences is an important basis for optimizing the preparation of workpiece processing programs. It can be considered from the aspect of machining trajectory and feed method.
When performing workpiece NC milling, it is necessary to select the proper feed method in combination with the technical requirements of the workpiece to ensure the workpiece cutting accuracy and processing efficiency. When milling the outer contour of a plane workpiece, the cutting and cutting routes of the tool should be arranged. Try to cut in and out along the extension of the outline curve to avoid the occurrence of knife marks at the intersection. At the same time, in the milling process, whether the milling or counter milling is to be selected according to the workpiece condition.
Third, the choice of tools and the correct installation
Whether it is a numerical control machining or an ordinary processing, the tool is directly acting on the workpiece, so it is the most important factor in the selection and installation of the workpiece processing accuracy and surface quality. In particular, the workpieces are machined on the CNC machining center. The tools are stored in the magazine in advance and they must not be replaced as soon as they are started. Therefore, the general principle of tool selection is: easy installation and adjustment, good rigidity, high durability and high precision.
Fourth, the reasonable choice of cutting amount The determination of the amount of cutting is an important part of the NC machining process, its size is an important parameter of the machine's main movement and feed movement, has an important impact on the workpiece machining accuracy, machining efficiency and tool wear. The choice of cutting amount includes cutting speed, amount of back knife, and feed amount. The basic selection principle is: when the rigidity allows, rough cutting takes a large depth of cut to reduce the number of passes and improve the productivity of the workpiece; finishing machining generally takes a smaller depth of cut to obtain a higher surface quality.
CATSU digging bucket is a type of Excavator Attachment that is used for digging and excavating soil, rocks, and other materials. It is typically made of heavy-duty steel and features sharp teeth or edges on the bottom to help break through tough materials. Digging buckets come in a variety of sizes and shapes to suit different excavation needs and can be attached to a range of different types of excavators.
When it comes to construction and excavation projects, having the right equipment is essential for efficient and effective work. Two commonly used attachments for excavators are digging buckets and sorting buckets. While both serve different purposes, they offer distinct advantages depending on the nature of the job at hand.
Advantages of Digging Buckets:
1. Excavation Efficiency: Digging buckets are specifically designed to penetrate the ground quickly and efficiently. They feature sharp teeth or cutting edges that enable them to break through various types of soil, rocks, and debris. This makes them ideal for digging trenches, foundations, or any task that requires substantial earthmoving.
2. Increased Productivity: The design of digging buckets allows for larger volumes of material to be moved at once. This, in turn, helps to increase productivity by reducing the number of passes required to complete a task. With a digging bucket, operators can save time and effort, ultimately accelerating the project timeline.
3. Versatility: Digging buckets come in various sizes and configurations, allowing for versatility in different excavation tasks. They can be equipped with different teeth options or additional features like tilt rotators, enabling operators to adapt to different soil conditions or project requirements.
Advantages of Sorting Buckets:
1. Enhanced Sorting Capabilities: Sorting buckets are specifically designed for separating materials on-site. They typically feature a grid or sieve-like structure that allows smaller particles to fall through while retaining larger ones. This makes them ideal for tasks like sorting rocks, debris, or separating different materials during recycling processes.
2. Cost and Time Savings: By using a Sorting Bucket, operators can eliminate the need for manual sorting or additional equipment, which can save both time and money. The ability to separate materials directly on-site eliminates the need for separate sorting facilities, reducing transportation costs and increasing operational efficiency.
3. Environmental Benefits: Sorting buckets contribute to environmental sustainability by enabling the separation and recycling of materials. By sorting and recycling on-site, construction projects can reduce the amount of waste sent to landfills, minimize the need for new raw materials, and lower the overall carbon footprint.
Conclusion:
While digging buckets excel in excavation efficiency and productivity, sorting buckets offer advantages in material separation, cost savings, and environmental sustainability. The choice between the two attachments depends on the specific requirements of the project and the desired outcomes. By understanding the advantages of each, construction professionals can make informed decisions and optimize their excavation processes.
