Abstract
A cutting machine control determines a required stock-removal amount from a work for each of sections into which a tool path is divided, and feeds the rotating cutting tool at a speed that is controlled according to the required stock-removal volume so that the rotating cutting tool removes a predetermined or target stock-removal volume of material for the component path section from a work per unit time.
Claims12
A cutting machine control method of controlling a cutting machine equipped with a rotating cutting tool for cutting a surface of a work, said cutting machine control method comprising the steps of:
- determining a required stock-removal volume to be removed from an object work along a tool path on the basis of a blank configuration of said object work;
- and
- variably controlling a tool feed speed of said rotating cutting tool along said tool path according to said required stock-removal volume so that said rotating cutting tool removes a predetermined stock-removal volume of material from said object work per unit time.
A cutting machine control method of controlling a cutting machine equipped with a rotating cutting tool having a plurality of cutting edges for cutting a surface of a work, said cutting machine control method comprising the steps of:
- determining a required stock-removal volume to be removed from an object work along a tool path on the basis of a blank configuration of said object work;
- and
- variably controlling a tool feed speed of said rotating cutting tool along said tool path according to said required stock-removal volume so that each said cutting edge removes a predetermined stock-removal volume of material from said object work per one revolution
A cutting machine control system for controlling a cutting machine equipped with a rotating cutting tool for cutting a surface of a work, said cutting machine control system comprising:
- means for determining a required stock-removal volume to be removed from an object work along a tool path on the basis of data on said tool path and data on a blank configuration of said object work;
- means for determining a tool feed speed of said rotating cutting tool along said tool path according to said required stock-removal volume so that said rotating cutting tool removes a predetermined stock-removal volume of material from said object work per unit time;
- said specified stock-removal volume from said object work;
- and
- means for feeding said rotating cutting tool at said tool feed speed.
A control medium for use with a cutting machine equipped with a rotating cutting tool having a plurality of cutting edges for cutting a surface of a work, said control medium recorded with a computer program that is run on a computer to execute the functions of:
- routing a tool path along which said rotating cutting tool is fed to cut an object work;
- dividing said tool path into a plurality of component path sections;
- determining a specified stock-removal volume of each said cutting edge per one revolution of said rotating cutting tool on the basis of information on said rotating cutting tool and said subject work;
- determining a required stock-removal volume to be removed from an object work for each said component path section on the basis of said information on said tool path and information of a blank configuration of said object work;
- and
- determining a tool feed speed of said rotating cutting tool along said component path section according to said required stock-removal volume so that said rotating cutting tool removes said specified stock-removal volume from said object work;
- and
- storing data of said tool feed speed of said rotating cutting tool for each said component path section.
