I. Foreword FAW Mould Manufacturing Co., Ltd. was founded in 1954. In the past 48 years, it has supplied body molds and technical services for FAW and more than 30 manufacturers in the country. In the mid-1990s, the trucks were produced. The company has made serious changes to the production of car molds. The company has further increased equipment investment and technical transformation in the past three years; it has introduced more than ten large-scale high-speed CNC milling machines from the national watch; so that our company's processing capacity is in the same industry. Domestic leading position. In the past, our company has always used EUCLID software as the leading programming software; but because the software has not been developed for many years; the software is low in programming power; the processing methods are few; it is difficult to get used to the needs of our production, after a steady investigation, Tested some of the world's leading CAD/CAM software; the company chose the PowerSHAPE and PowerMILL series of software from DELCAM in the UK; as our leading programming software today. For a year; our company chose this software to process and manufacture Chery Automobile Co., Ltd. More than 200 sets of molds, such as the company and Mazda Automobile Co., Ltd.; Masking molds account for the majority. After using DELCAM software; our programming power has improved by more than 50%; processing power has improved by more than 30%; tool life has also improved by more than 30%. Together with our company The DELCAM software has also been used to complete the localization of many high-end cars; the whole side of the Jetta car like FAW Volkswagen has a side mold; the mold is more than 5 meters long; the width is about 3 meters; the shape is messy; if imported from Germany; the price is very expensive It takes about 3 million RMB; after our company is localized, it only needs about 1 million RMB; it saves about 2/3 of the funds; like this high-precision; messy high-end car's entire cover mold; currently only in China Our company can make. The following is a mock-up mold for the entire side of the Jetta car; to analyze some of our company's successful experience in the production of car cover parts using DELCAM software; the software mainly includes modules such as PowerSHAPE and PowerMILL; And auxiliary production functions.
Second, the three-dimensional external Jetta car all sides of the imitation mold cavity some of us to use reverse engineering methods to make it; to PowerSHAPE process to make up. DELCAM company's software SHASHA software intelligentSHA and intelligent toolbar; Great locality has our operation; and its strong surface shape and surface modification function; especially suitable for the process to make up for the depiction.
Third, CNC machining The CAD model generated in the PowerSHAPE module is directly transmitted to PowerMILL; according to the characteristics of the side wall model; the NC machining process road is proposed; the process is as follows:
(1) Roughing because of the large amount of castings; roughing we use Ф50R6 round end milling cutter for layering processing. PowerMILL's layered processing can intelligently think about the casting amount of blank; optimize the tool path. Racing line roughing is PowerMILL's unique machining strategy; it maximizes the rounded corners to smooth the sharp corners of the tool path; and selects the selected cycloidal machining in the recessed area of ​​the tool overload; these fit the high speed The need for processing. After the practice of the test; the use of layered processing to save a lot of time compared to the parallel processing selected by us.
(2) Process after roughing The process of root clearing is to remove the data that cannot be processed at the concave corner of the rough or semi-finished part; thus the processing capacity of the next process is more uniform; The processing speed of the process; the intention to reach the progressive power. Because we have used large tools for roughing; there are still many residual margins in the groove area; therefore we decided to do a process after roughing. Because we need to use Ф20 ball-end knives during finishing; therefore, we also use Ф20 ball-end knives in this process. The selected processing strategy is PowerMILL's layered root processing based on common knowledge of blanks; Intelligently identify the unprocessed area after the previous processing; think about the residual margin left after the last processing; optimize the tool path of the remaining area;
(3) Semi-finishing Because roughing is only to remove too much margin; there is no need for appearance quality and precision; therefore, the selected layer height is large; after processing, a step-like margin is left on the exterior of the part. This appearance; leaving a uniform machining allowance for finishing; ensuring smooth tool force during finishing; stable cutting conditions; semi-finishing of parts is required. Semi-finishing we use PowerMILL to process according to the characteristics of the model. The shoal processing method; we choose the ball cutter of Ф30; with the 45° angle as the boundary; the PowerMILL shoal method will intelligently divide the model into the flat area and the steep area; the flat area we choose parallel processing; the arc connection, the steep area We use contour processing; we use rounded smoothing at the sharp corners of the parallel and contoured tool paths; and cooperate with the spiral feed method; these methods also meet the needs of high-speed machining; together Greatly improved our processing power and extended our tool life. This method of processing according to the model avoids parallel processing. Steep region of the tool carrier is too large; easy to form a broken tool; processing is a very good way.
(4) The process before the finishing process uses the pen-type rooting in the PowerMILL finishing strategy to remove the residual margin that cannot be processed at the concave corner; this greatly improves the finishing power.
