1) used on lathe for the manufacture of a shaped part 5 from a workpiece 4 along a copier 8. These systems have mechanical or electrical feedback.Īs an example, consider the operation of a copier control system with a hydraulic servo drive with mechanical feedback (Fig. The executive bodies of the machine, according to the initial information presented in the form of an analogue of the displacement program, reproduce this program for processing the workpiece.Īnalog control systems are classified into the following types: closed, open, copier with a servo drive.Ĭlosed-loop control systems control the executive body of the machine along the path (track), time (temporary), speed, power, pressure and other parameters.Ĭontrol systems driven by a copier, cam, ratchet and others that carry out a dosed movement of the executive bodies of the machine, as well as systems without a power amplifier (copy direct action) are classified as open.Ĭopier systems with a servo drive (hydraulic, electro-hydraulic or electric) have found wide application in machine tools of various types. Program carriers can be: stops located in a certain way on the machine, copiers, cams and camshafts. Analog control systems convert the initial information embedded in the program carrier in the pre-production process.
Towards a competitive sustainable manufacturing future, pervasive applications of virtual machining are not only technologically possible, but also make business sense, in this high material and energy cost world.Improving the productivity and quality of work on metal-cutting machines is associated with the mechanization and automation of the workpiece processing cycle.Ī control program is a set of commands in a programming language that corresponds to a given algorithm for the operation of a machine tool for processing a particular workpiece.ĭepending on the method of setting dimensional information, all machine control systems are divided into analog (non-numeric) and numeric. The virtual machine tool, which includes material removal animation and machine kinetic movement, can be controlled with a virtual CNC control panel and equipped with virtual jigs and inspection tools, such as dial indicator and wiggler, for immersive training of a young machinist. Working towards a vision of pervasive modelling and simulation, a unified voxel-based in-process geometry model for multiple-machining and 3D printing simulations is discussed with industrial applications of composite material plating simulation.
#Siemens sinutrain 840d math functions verification#
This chapter traces back the history of CNC simulation, analysis of the different CNC machining models, tested with application examples, and lists different CNC verification industry applications for the last 30 years. The evolution of deformable workpiece model from the 2D sections to 3D representations revolutionized not only the machining industry, but also pioneered the digital manufacturing age with virtual manufacturing. Since machining is a material removal process that will deform the workpiece geometry with cutting, the traditional rigid geometrical model could not be used to describe the in-process status of workpiece, which changes shape continually.

Virtual machining simulates NC code to discover errors, without a time consuming trial run or online debugging on real machine tool.
