Abstract
The invention discloses a numerical control system for a camshaft grinding machine and a control method thereof. The system comprises a numerical control system body and a non-circular grinding and processing environment module which is seamlessly embedded into the numerical control system body. The non-circular grinding and processing environment module can be used for realizing the non-circular grinding of a camshaft and comprises a part parameter and process parameter setting sub module, a file previewing and modifying sub module and a trajectory simulation sub module. According to the numerical control system disclosed by the invention, automatic control of the numerical control camshaft is used as background and the non-circular grinding and processing environment module of the camshaft is additionally arranged on the numerical control system, and thus the function requirement of non-circular grinding is achieved, a favorable operation effect is obtained and the roughness concentration of the camshaft surface is improved.
Description
Technical field
The present invention relates to the digital control system field, relate in particular to a kind of digital control system and control method thereof that is used for camshaft grinding machine.
Background technology
Along with the fast development of Domestic Automotive Industry, increasingly high requirement has been proposed for the quality of auto parts and components.In numerous parts, camshaft is exactly one of them critical component.The effect of camshaft is the unlatching and the closed action of control automotive engine valves; Its working order is related to the power and the service performance of an engine; And the rotating speed of camshaft is very high usually; And need bear very big moment of torsion, therefore very high to the requirement of the intensity of camshaft and profile fineness.Because the shape of camshaft part is complicated, requirement on machining accuracy is high, be that parts are made one of difficult problem always.
The cross section of camshaft is peach shape, rather than common being seen circle, so in grinding process, along with the rotation of cam workpiece (C axle), grinder wheel frame (X axle) also must keep synchro-feed, this processing method is called non-circular grinding.Non-circular grinding can be processed round piece, can process non-sired results part again, and has the advantage that frame for movement is simple, precision is high and precision keeps easily than traditional pattern processing mode.
Realize the non-circular grinding function aspects how, each lathe manufacturing firm generally realizes through digital control system is carried out secondary development, like the bag etc. that develops software of the OEM based on Siemens 840D digital control system.But costing an arm and a leg of inlet system, development difficulty are also bigger, and the operational effect that the non-circular grinding function of realization is actual is also as one wishes not to the utmost.
Summary of the invention
The objective of the invention is to overcome the defective of prior art and a kind of digital control system and control method thereof that is used for camshaft grinding machine is provided, it can reach the functional requirement of non-circular grinding, and operational effect is good, has improved the roughness on camshaft surface.
