Research On Key Technology Of Pipe Intersecting Line Groove Cutting CNC System

Intersecting line beveling is an important sign of country’s bridges, buildings, steelstructures, industrial development level, related to the development of our country’s economicconstruction, industrial construction. With the continuous development of the intersecting linebeveling, intersecting line bevel cutting CNC system is developing rapidly towardspecialization, intelligent, multi-functional direction. However, our research in this area is farbehind foreign countries. Around the intersecting line bevel cutting CNC systems theory andapplied researching has major practical engineering value and theoretical reference value.There is narrative domestic and abroad Current Situation of intersecting line bevel cuttingCNC system in this paper. on the basis of full understanding of the intersecting line trajectorymodeling, put forward a professional intersecting line beveling welding CNC system modeland study in-depth the CNC system model architecture, database functions, and keytechnology. Its main contents include:(1) For studying Cutting intersecting line trajectory calculation, error in the actual cuttinghas been calculated and compensate; The operation method of the motion compensation alsohas been put forward.(2) The requirement of all kinds of tubes intersecting line controlled cutting is fulfilled.By way of optimizing intersecting line cutting path algorithm, the function of main tube cut anumber of different directions and different diameter of the intersecting holes is achieved.Satisfy the intersection of branch pipe and main pipe with axis eccentric and non-eccentric,vertical or inclined. It can be cut on main pipe with multiple different directions an eccentricand non-eccentric square hole. It also can be cut cylinder intersecting line on the ends ofbranch pipe, meet the requirement of the intersection of branch pipe and main pipe with axiseccentric and non-eccentric.(3) The function of control cutting of pipe beveling is achieved. By optimizing trajectoryalgorithm of bevel cutting, optimized data added to the system. Using the system files controlthe entire bevel cutting in real-time.(4) The requirements for software of control system has been achieved. By using theVC’s MFC programming on the entire system to achieve a single shape cutting parametricprogramming; complete feature of the repeated cutting of single or combination cutting;control the given angle and variable angle bevel cutting; implement the function of automaticignition and rapid warm-up, automatic perforation process path generation, smooth, motioncontrol, automatically find the origin back to zero. It can have function of automatic alarmand diagnosis, recording operation event.By using CNC technology resources to study intersecting line bevel cutting CNC system, on the basis of that, the article study deep the intersecting line trajectory algorithm, andproposed a new algorithm of considering the new algorithm of the tube wall thickness of errorfactors affect the calculation of bevel. It provides an important reference for the intersectingline bevel cutting CNC system.
