Abstract
A controller for transferring information for managing and controlling machine tools, an automatic warehouse and a CNC device reads material information (e.g., size, shape, material) on an actual material on a pallet in an automatic warehouse before transferring a machining program for nesting. The controller judges whether the material information matches a material on which products are nested, newly nests the products of a machining schedule on the material of the material information when they do not match, and transfers the machining program for the nesting to the CNC device and machine tools.
Claims18
A nesting method for a machine tool control system in which a controller for transferring information for managing and controlling machine tools, an automatic warehouse and a CNC device nests the blanking shapes of products on a prestored material on a pallet of the automatic warehouse based on a machining schedule from a tool center and transfers a machining program for the nested products to the machine tool warehouse, said method comprising:
- reading material information on prestored material provided on the pallet of the automatic warehouse before transferring the machining program for nesting;
- judging whether the material information matches a planned material of the machining program;
- nesting products of the machining schedule on the prestored material provided on the pallet when the material information and the planned material do not match;
- and
- transferring the machining program for the products that have been nested.
A nesting method for a machine tool control system in which a controller for transferring information for managing and controlling machine tools, an automatic warehouse and a CNC device nests the blanking shapes of products on a prestored material on a pallet of the automatic warehouse based on a machining schedule from a tool center and transfers a machining program for the nested products to the machine tool side through the CNC device to blank the material on the pallet of the automatic warehouse, said method comprising:
- accessing information on an odd material to retrieve an odd material from which products to be interrupt nested, based on input from a terminal, can be blanked from the odd material information;
- and
- nesting the products to be interrupt nested on the retrieved odd material.
A nesting method for a machine tool control system in which a controller for transferring information for managing and controlling machine tools, an automatic warehouse and a CNC device nests the blanking shapes of products on a prestored material on a pallet of the automatic warehouse based on a machining schedule from a tool center and transfers a machining program for the nested products to the machine tool side through the CNC device to blank the material on the pallet of the automatic warehouse, said method comprising:
- accessing information on each pallet of the automatic warehouse to group products according to a delivery date and type of machining for post-processing of the machining schedule;
- retrieving a pallet having a shape capable of storing the grouped products from the pallet information;
- nesting storage positions of the grouped products on the retrieved pallet based on the grouping information;
- and
- transferring, based on said nesting, the storage positions of the grouped products to the automatic warehouse together with the machining program.
A punching method for a machine tool control system having a plurality of punching machines for punching a sheared material based on a transmitted machining program and causing the plurality of punching machines to punch the material in accordance with nesting information for the material, said method comprising:
- dividing the nesting information for punching by each of the plurality of punching machines and creating a plurality of machining programs for the respective divided nesting information;
- and
- transferring the plurality of machining programs to the respective punching machines simultaneously when different types of punching are made on the material.
A machine tool control system for use in a machining warehouse, said machine tool control system comprising:
- a tool center that stores a machining schedule for products to be machined;
- and
- a controller that transfers information for managing and controlling machine tools of the machining warehouse based on the machining schedule of said tool center, said controller comprising:
- a machining schedule file that stores the machining schedule of said tool center;
- a inventory master information file that stores inventory information, said inventory information including material information on prestored material provided on a pallet of the machining warehouse;
- a dynamic nesting schedule creation unit that nests the blanking shapes of products on the prestored material based on the machining schedule of said tool center and the material information in said inventory master information file;
- and
- a transfer unit that transfers a machining program for the nested products to a machine tool side of the machining warehouse to blank the material on the pallet of the warehouse,
- wherein, before the machining program for the nested products is transferred by said transfer unit, said dynamic nesting schedule creation unit reads the material information on the prestored material and determines whether the material information matches a planned material of the machining program and, when the material information and the planned material are determined not to match, said dynamic nesting schedule creation unit nests products of the machining schedule on the prestored material provided on the pallet.
A machine tool control system for use in a machining warehouse, said machine tool control system comprising:
- a controller that transfers information for managing and controlling machine tools of the machining warehouse based on a machining schedule for products to be machined, said controller comprising:
- a machining schedule file that stores the machining schedule which includes the delivery date and type of machining required for each product;
- a pallet information file that stores pallet information, said pallet information including information on the shape of each pallet provided in the machining warehouse;
- a grouping unit that groups products based on the machining schedule of the machining schedule file, said products being grouped according to the delivery date and type of machining that is required for each product;
- and
- a pallet drawing and nesting unit that retrieves the pallet information from said pallet information file and determines a pallet having a shape that is capable of storing the grouped products, said pallet drawing and nesting unit nesting storage positions of the products on each retrieved pallet,
- wherein said controller transfers the storage positions of the nested products to the machining warehouse together with a machining program for machining the products.
A machine tool control system for use in an automatic warehouse comprising plurality of punching machines for punching material based on a machining program and causing the plurality of punching machines to punch the material in accordance with nesting information, said machine tool control system comprising:
- means for dividing the nesting information for punching by each of the plurality of punching machines and creating a plurality of machining programs for the respective divided nesting information;
- and
- means for transferring the plurality of machining programs to the respective punching machines when different types of punching are made on the material.
