Problems solved by technology
When the shape of the workpiece is measured in the processing equipment, the cycle time becomes longer, so the processing efficiency may decrease
In addition, when machining is stopped for a long time to measure the workpiece, the temperature of the machining equipment drops during the measurement period, and the temperature rises again during machining, so the machining accuracy may decrease due to thermal displacement.

Embodiment Construction
[0019] Embodiments of the present disclosure will be described below with reference to the drawings. figure 1 It is a schematic diagram which shows the structure of the processing system 100 which concerns on one Embodiment of this disclosure. The machining system 100 processes a workpiece W.
[0020] The processing system 100 includes: a jig 1 for holding a plurality of workpieces W; a measuring device 2 for measuring a plurality of workpieces W held on the jig 1; and a processing device 3 for processing the workpiece W held on the jig 1. Multiple workpieces W.
[0021] Such as figure 2 As exemplified in , the jig 1 has a plurality of holding portions 11 for holding the workpiece W, and a reference portion 12 for positioning or detecting the position of the processed device 3 .
[0022] For each workpiece W, the holding unit 11 holds each workpiece W on the jig 1 so as to be relatively immovable from being measured by the measuring device 2 until being processed by the p...

The invention provides a machining system and a machining method, which can accurately measure the position of a workpiece without increasing the machining cycle time. The machining system according to an aspect of the present disclosure includes: a jig which retains a plurality of workpieces; a measurement device which measures a plurality of workpieces retained on the jig; and a machining devicewhich machines the plurality of workpieces retained on the jig, in which the jig has a reference part which is positioned or position detected by the machining device, and in which the measurement device has: a measurement unit which measures a positional relationship of the plurality of workpieces retained on the jig relative to the reference part, and an input unit which uses a recording mediumor communication to input positional information of the plurality of workpieces measured by the measurement unit to the machining device, and in which the machining device has: a jig coordinate system specifying unit which specifies a coordinate system of the jig, by positioning or position measuring the reference part of the jig, and a workpiece coordinate system setting unit which individuallysets coordinate systems of each of the plurality of workpieces, based on a coordinate system of the jig specified by the jig coordinate system specifying unit, and the positional information inputtedfrom the input unit.
Description
technical field [0001] The invention relates to a processing system and a processing method. Background technique [0002] For example, when a workpiece is processed in a processing device such as a machining center, it may be necessary to measure the position (including posture information) of the workpiece held in the processing device to determine the relative position of the tool and the workpiece. When the shape of the workpiece is measured in the processing equipment, the cycle time becomes longer, so the processing efficiency may decrease. In addition, when the workpiece is measured while the machining is stopped for a long time, the temperature of the machining device drops during the measurement, and the temperature rises again during machining, so that machining accuracy may decrease due to thermal displacement. [0003] As a method of measuring the position of the workpiece in a relatively short time, there is a method using image processing technology. As an ex...
