Abstract

As wear occurs on the cutting tool, there is a change, at irregular intervals, of the tool locating surface against the workpiece. This change occurs when the first projection is worn down and the next comes into contact with the workpiece. The difference is detected by measuring the variations in cutting force vibration, temp. or similar.

Description

15 20 25 456 564 2 Pâ grund av att övergången från B till C sker konti- nuerligt har det visat sig vara svårt att med erforderlig noggrannhet detektera slutet av området B. Ändamålet med föreliggande uppfinning är att genom I en speciell utformning av verktygets släppningsyta, där fasförslitningen uppstår, skapa en skarpare övergång från B till C. Due to the fact that the transition from B to C takes place continuously, it has proved difficult to detect the end of the area B with the required accuracy. The object of the present invention is that by in a special design of the clearance surface of the tool, where phase wear occurs, create a sharper transition from B to C.

Detta ändamål uppnås genom att verktygets V släpp- ningsyta förses med minst två stycken avsatser enligt figur 3.This object is achieved by providing the clearance surface of the tool V with at least two ledges according to Figure 3.

Släppningsvinkeln för avsatserna görs 0° eller nära 0°. Höjden a för avsats 1 väljs så att den över- ensstämmer med fasförslitningen vid övergång från B till C enligt figur 2.The clearance angle of the ledges is made 0 ° or close to 0 °. The height a for ledge 1 is chosen so that it corresponds to the phase wear at the transition from B to C according to figure 2.

Höjden b för fas 2 väljs så att a + b motsvarar en fasförslitning inom omrâdet C (fig 2), vilken fort- farande ger ett acceptabelt bearbetningsresultat.The height b for phase 2 is chosen so that a + b corresponds to a phase wear within the area C (Fig. 2), which still gives an acceptable machining result.

Vid bearbetning med ett verktyg enligt föreliggande uppfinning kommer fasförslitningen som funktion av in- greppstiden att få ett principiellt förlopp enligt figur 4.When machining with a tool according to the present invention, the phase wear as a function of the engagement time will have a principled course according to Figure 4.

Den stegvisa övergången från B till C som uppstår då avsats l slitits, så att fashöjden plötsligt övergår från a till a + b, kan utnyttjas för initiering av verk- tygsbyte. Detekteringen kan ske genom mätning av skär- kraftsförändringar, vibrationsförändringar, temperatur- förändringar eller dylikt. s 1.1The step-by-step transition from B to C that occurs when ledge 1 is worn, so that the phase height suddenly changes from a to a + b, can be used to initiate tool change. The detection can take place by measuring shear force changes, vibration changes, temperature changes or the like. s 1.1
