Exploring the Application of Cutting and Layout in CNC Cutting Process

It can detect the dimensions of the drawn parts, ensure the accuracy of the graphics, and ensure the machining accuracy of the parts; store the parts information, such as part name, drawing number, material, thickness and other parameters, which is convenient for database calling and management, such as CAPP, ERP, etc.; set the cutting path of the part, cutting compensation, etc.; output the NC code of the part; verify the NC code of the part; can transfer the appropriate sheet from the stock, arrange the part for the part; adjust the part The number of parts, the cutting distance of the parts, the form of the lead-in leads, and the like.

Set the meaning of the arrangement. Flexible. It can adapt to the processing of parts with different shapes to meet the requirements of fast and agile manufacturing. Can meet market demand. It can meet the requirements of single-piece, small-batch, trial production, reduce the use of shearing machine processing, and increase the cost of the mold, and the cycle is long. The tailoring software has a variety of complex algorithms, flexible definition conditions, and highly integrated expert systems. The arranging scheme is more reasonable, feasible, economical and many other factors, and has the function of expert intervention, making the layout scheme more implementable; powerful database management function. The arranging and arranging software is an integration of a plurality of data including a graphic database and a material library library, which is easy to manage and can be connected with information systems such as CAPP and ERP in modern enterprises, and can enable the process department, the material department, and the production department. Parallel management. The operation speed is fast. Using the fast floating-point computing speed of the computer, the data processing is not only efficient, but also accurate, fast and fast, which is unmatched by any craftsman. Easy to program. The reason why various CNC software is widely used is that it can be automatically executed from data acquisition, programming to part processing, with low error rate and high programming efficiency. Optimize the layout, and automatically calculate the quota statistics for the sheet stock and residual stock, and play the auxiliary management function for the residual materials and quota.

Database Management Function Module This function module is a new function added according to the requirements of the development of information technology of our company. It mainly refers to the cutting parameters of the above functional modules, the name of the sampled parts, the material, the quantity, the geometrical dimensions of the sheets, the utilization rate, etc. And the cost estimation and other data for timely statistics, available for ERP, CAPP and other systems to provide data.

The application of the cutting software in the railway wagon is analyzed by the specific application of the double-deck container flat car produced by our company. The FASTCAM CNC cutting and cutting software and the special database are used to set the layout of the parts of the double-deck container flat car. The utilization rate of the board has been greatly improved. The FastCAM layout drawing can also be used as an operation card output to guide and standardize the operator's operation behavior, and at the same time, the manufacturing cost is also predicted in advance. Benefit Analysis If the plate is calculated at 4,000 yuan/t, the plate consumption is 50,000t/year, then the annual cost is 4 million yuan.

Saving and reducing consumption is one of the problems that cannot be avoided in the future development of various enterprises. It is the only way for enterprises to explore their inherent potential and create economic benefits. CNC cutting optimization nesting software as an auxiliary management tool, its promotion and application is the perfection and supplement of cost management.
