Abstract
A device configured to predict an execution time of an auxiliary function for tool change extracts an auxiliary function command for tool change from a machining program, calculates the storage position of a before-exchange tool and the storage position of an after-exchange tool, based on the auxiliary function command, and calculates a distance between tools, based on the results of the calculation. Also, the prediction device predicts the execution time of the auxiliary function command for tool change with reference to a database in which the distance between tools is associated with an actual value of the auxiliary function execution time for tool change.
Claims4
A machining time prediction device configured to predict an execution time of an auxiliary function for tool change, the machining time prediction device comprising:
- a tool change auxiliary function command extraction unit configured to extract an auxiliary function command for tool change from a machining program;
- a tool position calculation unit for positions before and after tool change configured to calculate the storage position of a before-exchange cool and the storage position of an after-exchange tool, based on the auxiliary function command;
- an inter-tool distance calculation unit configured to calculate a distance between tools, based on the storage position of a before-exchange tool and the storage position of an after-exchange tool;
- and
- a tool change time prediction unit configured to predict the execution time of the extracted auxiliary function command for tool change with reference to a database in which the distance between tools is associated with an actual value of the auxiliary function execution time for tool change.
