Casting grinding track generation method and system

Abstract

The invention discloses a casting grinding track generation method and system. The casting grinding track generation method comprises the following steps that a pattern extraction module obtains a standard contour map of a to-be-ground workpiece, the modification and adjustment are carried out according to the actual boundary dimension of the workpiece, and an actual contour map of the to-be-ground workpiece is obtained; a task planning and process parameter input module is used for carrying out task planning on a to-be-ground area according to the grinding process requirements and configuring grinding process parameters to obtain segmented grinding task information and process parameter configuration information; according to the information, a grinding track generation module generates proposed grinding track data information and a grinding track graph; in combination with actual production process requirements, a grinding track editing module modifies the planned grinding track data information and the grinding track graph to obtain optimized grinding track data information and grinding track graph; and a process program generation module extracts the optimized information and generates a process program file directly used for processing according to a production equipment programming rule.

Description

technical field [0001] The invention belongs to the technical field of casting grinding, and relates to a method and system for generating grinding tracks of castings. Background technique [0002] During the casting process of cast workpieces, redundant parts such as flashes, burrs, and risers will be formed on the surface of castings due to technological requirements, which will affect subsequent machining processes and appearance characteristics of workpieces. At present, the equipment used in automatic casting grinding includes special grinding robots and general-purpose six-axis robot grinding lines. The grinding process programs need to be compiled through manual online teaching. However, there are many problems in manual online programming, which are mainly reflected in the programming process. Equipment shutdown is required, the programming process is cumbersome, and it is difficult to teach complex motion trajectories, which is inefficient and the programmer is in a...

Problems solved by technology

At present, the equipment used in automatic casting grinding includes special grinding robots and general-purpose six-axis robot grinding lines. The grinding process programs need to be compiled through manual online teaching. However, there are many problems in manual online programming, which are mainly reflected in the programming process. Equipment downtime is required, the programming process is cumbersome and it is difficult to realize the teaching of complex motion trajectories, which is inefficient and the programmer is in a dangerous working environment

[0003] Therefore, automatic grinding equipment is faced with difficult application technology, low efficiency of new product launch, high maintenance cost, etc., which seriously restricts the large-scale promotion and application of such equipment.
