Metal member, processing system, and method for manufacturing metal member

A processing system comprising:

• a drilling tool and a chamfering tool that process a workpiece made of a metal member;
• a first drive mechanism that operates the drilling tool;
• a second drive mechanism that operates the chamfering tool;
• a controller that controls the first drive mechanism and the second drive mechanism;
• and
• a measurement unit that acquires a first physical quantity and a second physical quantity related to the control of the first drive mechanism,
• wherein the workpiece includes:
• a first plate including a first front surface and a first back surface;
• a second plate including a second front surface and a second back surface;
• and
• a leg that fixes the first plate and the second plate such that the first back surface and the second back surface face each other at an interval,
• wherein the controller is configured to control the first drive mechanism to operate the drilling tool so as to coaxially and sequentially process;
• (i) a first hole penetrating the first front surface and the first back surface, and (ii) a second hole provided in the second plate,
• the first hole is a hole including:
• (a) a front-side first opening edge provided in the first front surface, and (b) a back-side first opening edge provided in the first back surface,
• the second hole is a hole including a back-side second opening edge provided in at least the second back surface,
• wherein the controller is configured to control the second drive mechanism to operate the chamfering tool so as to provide a first chamfered portion at a first opening edge of at least one of the front-side first opening edge and the back-side first opening edge, and to provide a back-side second chamfered portion at the back-side second opening edge,
• wherein the first physical quantity is a feed speed of the drilling tool, and the second physical quantity is a first time from a start of drilling the first plate to a start of drilling the second plate, and
• wherein the controller;
• obtains:
• (ai) a position of the at least one first opening edge and (aii) a position of the back-side second opening edge, both the position of the at least one first opening edge and the position of the back-side second opening edge are obtained based on the first physical quantity and the second physical quantity, and
• controls the second drive mechanism based on the position of the at least one first opening edge and the position of the back-side second opening edge.
