DEVICE FOR DEVELOPING PROGRAMMES, DEVICE FOR COMPUTER NUMERICAL CONTROL, PROGRAMME GENERATION METHOD

摘要

FIELD: machine building industry. ^ SUBSTANCE: inventions are referred to machine-building industry and may be used for controlling mechanical treatment of work pieces by using computer numerical control programme. The device for computerised numerical control of mechanical treatment includes device for generating programmes. The device ensures that programme is generated based on the data from the machined work piece shape and data on tolerable limits for shape data. The device contains a calculation unit of target mechanical treatment sizes, processing unit of shape data distortion and mechanical treatment programme generation unit. The tolerable limit data contain data on changed positions, relating to the method of moving graphical elements. The processing unit of shape data distortion is designed so that graphical elements positions can be set after their movement based on the above information on position change. ^ EFFECT: simplified preparation of computer numerical control programme, considering tolerable limits for variety of treated surfaces in work piece. ^ 5 cl, 14 dwg
