Abstract

A cutting apparatus is capable of cutting a work-piece depending upon the quality of the work-piece. The cutting apparatus produces parallelism between a knife edge of a cutting blade and a mounting face of the work-piece. A support having the blade is provided to a column capable of controlling a tilting angle of the blade in a blade length direction. Cutting is executed by controlling vertical movement of the blade. A driving source is capable of controlling movement linearly. The driving source produces a parallel relationship between a surface of a table and a knife edge. Different supports are each unitized to include a driving source and the blade vertically moved by the driving source. The different supports can be mounted interchangeably and selectively on a column of a cutting apparatus.

Dependent claims

A cutting apparatus comprising a column and a support supporting a cutting blade having a knife edge, said support being configured to control a tilting angle of the cutting blade in a blade length direction, and the cutting blade being driven to be vertically movable relative to the support by a driving source supported by said support;

wherein an index table having a surface for positioning a work-piece, a driving source of the cutting blade, and a tilter configured to control the tilting angle of the support are respectively linked with a controller;
and
wherein said controller processes and stores a tilting angle data by collecting a driving amount of the driving source of the cutting blade as the cutting blade being tilted in the blade length direction relative to the surface of the index table, the tilting angle data being processed by bringing a one end side of the knife edge and an opposite other end side of the knife edge into contact with the surface of the index table by lowering the cutting blade from an original top dead center position, in a state where said cutting blade is slanted by a same angle respectively on the one end side and the opposite other end side in the blade length direction both before and after turning said index table by an angle of 90 degrees, and
wherein said controller processes and stores a parameter of a lowering amount data of the cutting blade at a time of moving the cutting blade by a prescribed pitch, from a driving amount of the driving source of the cutting blade, by bringing the knife edge of the cutting blade into line contact with the index table, by lowering the cutting blade from the original top dead center position by moving the cutting blade tilted by the tilting angle data, by a prescribed amount in a direction orthogonal to the blade length direction.

A cutting apparatus comprising a column and a support supporting a cutting blade, said support being configured to control a tilting angle of the cutting blade in a blade length direction, and the cutting blade being driven to be vertically movable relative to the support by a driving source supported by said support,

wherein a sensing portion, movable in a blade length direction of a lowering cutting blade and extending parallel relative to a surface of an index table in a direction orthogonal to the blade length direction, is mounted on the surface of the index table,
wherein the index table, the sensing portion, the driving source of the cutting blade, and a tilter configured to control the tilting angle of the support are respectively linked with a controller;
wherein said controller processes and stores a tilting angle data of the cutting blade in the blade length direction by detecting a plurality of points of a knife edge in the blade length direction, using said sensing portion mounted on the surface of the index table, both before and after turning the index table by an angle of 90 degrees, and
wherein said controller further processes and stores a parameter of a lowering amount data of the cutting blade at a time of moving the cutting blade by a prescribed pitch, based upon a driving amount of the driving source of the cutting blade and based upon detecting the knife edge by said sensing portion, after moving the cutting blade by a prescribed amount in a direction orthogonal to the blade length direction.
