A method for continuous measurement of three-coordinate measuring machine workpieces

Abstract

The invention discloses a three-coordinate measuring machine workpiece continuous measurement method which comprises the steps of a step of measurement program management and measurement parameter setting, a step of measurement task management and measurement task automatic scheduling, and a step of measurement workpiece offline centering and quick change positioning. Tasks such as measurement program switching, report storing, uploading and measurement timing are automatically scheduled and finished by a system. A plurality of workpieces can be simultaneously loaded for realizing combined measurement. A manually established coordinate system and automatic operation are integrated. Measurement personnel do not require high-frequency operation of a computer and a measurement machine, thereby reducing measurement time and workload of the measurement personnel, so that the measurement personnel have more energy for performing offline loading and workpiece alignment. When the measurement machine automatically operates through controlling of a scheduling system, the measurement personnel performs offline loading for alignment of a next workpiece. The measurement machine and a person perform parallel operation, thereby reducing waiting time of the person and the machine, ensuring continuous operation of the measurement machine, and improving integral measurement efficiency and utilization rate of the measurement machine.

Description

technical field [0001] The invention relates to a method for continuously measuring workpieces of a three-coordinate measuring machine. Background technique [0002] At present, when measuring workpieces with three coordinates, it is necessary to write measurement programs for each workpiece. These measurement programs are scattered in the computer. When a workpiece needs to be detected, the measurement program of the workpiece is called from the measurement software, the coordinate system is manually established, and then Run the program, after the operation is completed, you need to manually save the measurement report to the computer. If necessary, the report has to be sent to other computers for viewing by relevant personnel. In this process, each step requires manual operation by the surveyor, which is inefficient. When the surveyor is operating the software, the measuring machine does not work, which increases the waiting time of the measuring machine. The surveyors ...

Problems solved by technology

[0005] With the rapid development of technology, some measurement software has added measurement program running software, adding the measurement program to the interface, and the measurement program can be directly run on the interface, which simplifies the operation to a certain extent, but these software and measurement The software is the same, it is all for a single measurement task, it cannot automatically switch the measurement task, and cannot realize the automatic scheduling of multiple measurement tasks, so that the measuring machine cannot be continuously measured, and the overall efficiency and utilization of the measuring machine can be improved

[0006] Recently, there are also some general-purpose fixtures for three-coordinate measurement. These fixtures are expensive, and the same part can be clamped. When the measured parts are different, it is time-consuming to reassemble the fixture.

Of course, special fixtures can also be used, that is, a set of fixtures is specially designed for each part. This method is acceptable when the production volume is large and the variety is small. When there are many measurement varieties in a unit, so many special fixtures are used. It is unacceptable both in terms of cost and difficulty of management

[0007] To sum up, most of the current three-coordinate measurement and programming work is mainly based on the measurement of a single workpiece, and the efficiency of single workpiece measurement is acceptable. The order of tasks, the combination of measurement tasks, the switching of workpieces, the switching of measurement programs, and the collaborative work of people and measuring machines, so that the measurement efficiency cannot be improved as a whole

The real effective working time of the measuring machine is short, the measuring process is discontinuous, the working efficiency of the measuring machine is low, the utilization rate of the measuring machine is low, most of the measuring machines are in invalid working hours, and cannot be effectively utilized
