Measure grinding (calm dimension grinding) characteristic and device

Measure grinding, also say to decide dimension grinding. Its characteristic is, place of consideration process designing sets origin and actual grinding origin, through the measurement of make choice of the coordinate of partial diameter is worth, make every workpiece measures the diameter after partial grinding, keep basically consistent, can prevent what indirect measurement arises effectively to accumulate an error. (1) measuring measurement unit of grinding device external diameter is in grinding process the dimension to workpiece undertakes be metricaled directly, it is result change telegraphic date, when reaching set size, give out telegraphic date to come to those who control emery wheel head to exit. Answer before grinding begins dimension of accurately set external diameter arrives at 0 o'clock, and set is good the dimension position that issues signal. Graph 7-8 is denotive it is to measure grinding process, dot of signal of 1P, 2P leads reference point for feed, 3P signal dot is at 0 o'clock, namely exact size dot. The slope of line of process of the feed in this graph is bigger, feed rate is older. To measuring grinding, the place when process designing compiles the changeover position that feed leads, express the signal that issue to control by the measuring instrument, so of process designing cut deep need not be very accurate. Graph the 9 approach that express to a kibble, essence is ground and do not have scintilla grinding and odd motion quantity. Each measure set signal, answer to dictate in each the midway that cuts a cost is given out, ability of so next block is started. Graph 8 measure grinding to pursue 9 grinding surplus and approach (2) actual " measure grinding " the program uses bouncing function commonly (G31) or (/ ) come process designing. The reentry after measuring a head to be ground in workpiece oxidation skin arrives it is better to measure the place. CNC Milling
