For the convenience of adjusting the welding torch , the welding torch is made to move with a even speed in x axes direction and is adjusted in y axes direction according to the data read , so that real - time seam tracking is implemented
Y coordinate measuring top to bottom . the coordinates start at the upper - left corner of the form , so if you wanted to draw a single dot 10 pixels from the left and 10 pixels down , you would express the x and y coordinates as
The research results indicated that by comparing the differences between aggregate moments of inertia to x axis and to y axis , i . e . , the index of the aggregate distribution in asphalt mixture , it is feasible to evaluate quantitatively segregation
Basing on y - axis " function request and design indexes of binary optical element ' s laser direct writing equipment , and simply contrasting with other projects of high - precision transmission system design , the paper puts forward the project of total structure design of the transmission system
Finally , subtract it from 1000 . this is done because the y - values run positively down the page . the x - axis is drawn horizontally at a y height of 1000 pixels , so to determine how high this calculated y position is above the x - axis , you subtract it from 1000
The mechanism is based on the 4 - axis rectangular coordinate system . the driven mode of x - axis is proportional pneumatic - servo control system ; y - axis is driven by a digital ac servomotor ; z - axis is driven by a linear cylinder ; the driven mode of the axis of r is same to that of y - axis
