Abstract
The invention relates to a display processing apparatus which may be used in instances when a single display is to be used to represent multiple parameters whose values may be correlated or interrelated with one another. The invention is particularly useful when simultaneously displaying a plot of position vs. time and some other parameter whose value changes with position, time, or both. Correlative display is made possible by a technique which samples the values of all of the related parameters at intervals, and stores the sampled values along with an indication of the elapsed time. In this manner, positional or other parametric data corresponding to distinct points or ranges of time can be extracted and displayed in time-correlated fashion.
Claims13
A numerical control device for an electric discharge machining apparatus comprising:
- a timer unit for counting the elapsed time of electric discharge machining;
- a machining parameter measuring unit for measuring a machining parameter;
- a current position detecting unit for detecting a current position;
- a sampling unit for periodically and concurrently sampling the elapsed time data, the machining parameter data and the current position data;
- a memory unit for storing the sampled data and machining condition data;
- display means for presenting a machining trace graphic display and a graphic display illustrating the variation of said machining parameter data with elapsed time, based on the data stored in the memory unit;
- and
- a display correlating unit for relating the elapsed time data, the machining parameter data and the current position data together to cause the display means to present the machining trace graphic display and the display showing the machining parameter data in correlation.
A system for displaying plural correlatable parameters, comprising:
- a timer unit for counting elapsed time;
- a parameter measuring unit for measuring selected parameters;
- a sampling unit for periodically and concurrently sampling the elapsed time and current values of said selected parameters, wherein at least a first of said parameters varies with time, and a second of said parameters varies as position;
- a memory unit for storing the sampled data;
- display means for presenting displays illustrating the first and second parameters, based on the data stored in the memory unit;
- and
- display correlating means for relating the elapsed time, the first parameter data and the second parameter data together to cause the display means to present the first parameter data and the second parameter data in correlative relation.
