How to choose the knife road for four-column hydraulic press is more effective?
The four-column hydraulic press can ensure the effective processing by selecting the correct tool path. The so-called hydraulic press tool path is the movement track of the tool in the whole machining process. It not only contains the contents of the work step, but also reflects the order of the work step.
The road of four-column hydraulic press is one of the basis of programming. The following points should be paid attention to when determining the path of knife: seeking the shortest processing road, reducing the time of empty knife to improve the processing power as shown in the hole system on the parts. Hydraulic press knife road for the first processing of the outer ring hole, and then processing the inner ring hole. If you use the c map of the road, you can save the positioning time nearly double.
In order to ensure the roughness requirement of the workpiece after the surface processing, the hydraulic press should organize the cutting road to process the inner cavity by the method of line cutting. This kind of knife can remove all the allowance in the inner cavity without leaving a dead angle. Do not hurt summary. The hydraulic press but line cutting method will leave a residual height between the starting point and the end of the two knives, and the hydraulic press will not reach the required surface roughness. Hydraulic press, such as the selection of b map of the road, the first line cutting method, and finally along the circumferential ring cut a knife, smooth summary of the appearance, can achieve a better effect. It is also a better way to walk the knife.
The cutting or cutting point of the cutting tool should be on the tangent line along the part summary, the hydraulic press should ensure the workpiece general lubrication; the hydraulic press should prevent the workpiece surface from scratching vertically and lower on the workpiece general surface; Try to reduce the pause in the general cutting process (cutting force suddenly changes to form elastic deformation), avoid leaving knife marks.
