Abstract
The objective of the present invention is to provide a tool measuring system, a control method, and a program with which it is possible for a cutting tool to be measured easily. This tool measuring system is provided with: a tool measuring device; a tool moving unit; a tool measuring unit; a tool correcting unit for feeding back the measured tool length and tool diameter of the cutting tool to a tool diameter correction number and a diameter correction number of the cutting tool; and a program computing unit for computing the operations of the tool measuring device, the tool moving unit, the tool measuring unit, and the tool correcting unit as instructions operable by the machine tool from a one-line control program in order to instruct the machine tool.
Claims7
A tool measuring system comprising:
- a processor;
- and
- a tool measuring instrument that detects an edge of a cutting tool in a machine tool,
- wherein the processor is configured to:
- move the cutting tool to the tool measuring instrument in the machine tool;
- measure length and diameter of the cutting tool based on coordinates of the edge detected by the tool measuring instrument;
- feed back the measured length and diameter of the cutting tool to tool length correction numbers and diameter correction numbers for the cutting tool, the tool length correction numbers being numbers for correcting the tool length according to a specified number, and the tool diameter correction numbers being numbers for correcting the tool diameter according to a specified number;
- and
- compute a command executable by the machine tool from a one-line control program for commanding the machine tool,
- wherein the one-line control program includes at least a G-code, a measurement mode, and the tool length correction numbers and diameter correction numbers, and the G-code is a code for measuring the cutting tool according to the one-line control program in the machine tool.
A method for controlling a tool measuring system, comprising:
- a step of computing a command executable by a machine tool from a one-line control program for commanding the machine tool;
- a step of detecting an edge of a cutting tool in the machine tool according to the executable command;
- a step of moving the cutting tool to a tool measuring instrument in the machine tool according to the executable command;
- a step of measuring, according to the executable command, length and diameter of the cutting tool based on coordinates of the edge detected by the tool measuring instrument;
- and
- a step of feeding back the measured length and diameter of the cutting tool to tool length correction numbers and diameter correction numbers for the cutting tool according to the executable command, the tool length correction numbers being numbers for correcting the tool length according to a specified number, and the tool diameter correction numbers being numbers for correcting the tool diameter according to a specified number,
- wherein the one-line control program includes at least a G-code, a measurement mode, and the tool length correction numbers and diameter correction numbers, and the G-code is a code for measuring the cutting tool according to the one-line control program in the machine tool.
