Problems solved by technology

The surface processing effect of the workpiece is not only affected by the state of the machine tool itself, but also one of the major influencing factors is the control of the processing technology. Once the control is not in place, it will be difficult to realize the evaluation of the basic motion state of the machine tool
Moreover, it is not convenient to quantify the data standards for the abnormal lines that appear in the actual processing at present, and it is even more inconvenient to carry out digital management
At the same time, frequent processing verification not only has a large workload and low efficiency, but also easily leads to waste of resources and high cost

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, a visual evaluation method of a machine tool basic motion state of the present invention specifically includes the following steps:

[0027] Step 100, start the CNC machine tool, and perform dry run-in according to the imported workpiece processing path;

[0028] Step 200, extract and collect data on the actual load (output current) of the driving motor of the motion unit of the CNC machine tool through the analog quantity acquisition card, wherein the motion unit includes each linear axis motion unit of the machine tool, the rotary axis motion unit and the electric spindle rotation motion unit;

[0029] Step 300, fitting the real-time position data of the waypoints into a three-dimensional graph, and separately mapping the load data of each motion unit collected synchronously to the three-dimensiona...

Abstract

The invention belongs to the field of numerical control equipment, and particularly relates to a visual evaluation method and device for the motion state of a machine tool foundation. The method is characterized in that a workpiece machining path is in idle running-in through a machine tool, real-time load data of driving motors of all movement units of the machine tool are extracted through an analog quantity acquisition card, the load size of each point on the workpiece machining path is reflected in a chromatogram form, and then whether the movement state of the machine tool is abnormal or not is analyzed. According to the invention, actual cutting machining is not needed, operation is easy, efficiency is high, cost is low, and index quantification and digital management are easy to achieve.

Description

technical field [0001] The invention belongs to the field of numerical control equipment, and in particular relates to a method and device for visually evaluating the basic motion state of a machine tool. Background technique [0002] The basic motion state of the machine tool is very important for the stability of the machine tool motion. The quality of the basic motion state of the machine tool directly affects the processing effect of the workpiece surface, such as some abnormal lines on the workpiece surface. At present, the evaluation of the overall state of the machine tool usually uses the actual processing of the machined test piece, and judges and verifies it according to the surface processing effect of the workpiece. The surface processing effect of the workpiece is not only affected by the state of the machine tool itself, but also one of the major influencing factors is the control of the processing technology. Once the control is not in place, it will be diffic...
