Computerized Numerical Control (CNC) is a programmable automation type which various machining operations are carried out by microcomputers, and is directed by mathematical data. CNC can control the motion of tool or work piece, also the input parameters such as depth of cut, feed, speed, and functions such as turning coolant on/off and turning spindle on/off. CNC is used when high quality and effectiveness is required. Short production time, high manufacturing accuracy, greater manufacturing flexibility, reduction in human errors and contour machining are major benefits of CNC. Growth in machine tool industry has been a major contributing factor in this market; also the demand from retrofit segment has increased. However, high investment requirements may pose challenge to the growth of CNC market. High maintenance cost and requirement of skilled part programmer may act as market restraints.
By application, Aerospace sector and automotive sector have been major markets for CNCs. Industries such as woodworking, healthcare, jewelry and food industry have started adopting high performance CNCs. CNCs have been focused on large market segments of metal working machinery and machine tool market; and relatively smaller target which includes various cutting and material contouring applications in glass, wood and plastic.
CNC are classified into machine tool and non-machine tool areas. CNC are used for milling machines, drill press, grinding units, lathe machines, lasers, etc., in machine tool category; for coordinate measuring machines, wielding machines, electronic assembly, winding machines, etc., in non-machine tool category. Demand for machine tool category expected to be high while demand for non-machine tool is expected to increase in future.
By class, CNC can be differentiated as high end class, middle range and low end classes. Major focus has been on high range class. Market demand for low range class is expected to increase on a large scale as domestic manufacturers have been seeking to improve their manufacturing competency, while market demand for middle range class is expected to increase at moderate pace.
CNC have been in demand in various regions such as Europe, North America, and Asia Pacific. Demand for CNC is expected to increase in Asia Pacific and North American regions. Western Europe is expected to continue as dominant region.
The market space is dominated by Mitsubishi Electric Corp., Siemens AG and Fanuc Corp. Other market players are Heidenhain GmbH,GSK CNC EQUIPMENT Co. Ltd., Fagor Automation, Soft Servo Systems, Sieb & Meyer AG and Bosch Rexroth AG.
