TRAORI - parameter and axis direction

Y0 = right side of table (seen from front of table)

Z0 = machine table surface

A0 = spindle pointing downwards (6 o’clock position)

X = positive is towards back of table

Y = positive is towards left

Z = positive is upwards

A = clockwise (view from front of the machine backwards)

C = counterclockwise (view from top of machine downwards) .

Hello,

We using TRAORI function for swivel head. TRAORI type is 24.
now when ourA axis is rotating after TRAORI activez axis is moving on positive direction(according to machine Z axis should move to negative direction). we tried by changing Z axis to opposite direction but that timeX and Y axis movement is not perfect. please check below information and parameter(attached). and give us somesolution.

1. Axis origins

X0 = front of table

Y0 = right side of table (seen from front of table)

Z0 = machine table surface

A0 = spindle pointing downwards (6 o’clock position)

C0 = spindle nameplate pointing towards front of machine (A axis gearbox pointing to back of machine)

2. Axis directions

X = positive is towards back of table

Y = positive is towards left

Z = positive is upwards

A = clockwise (view from front of the machine backwards)

C = counterclockwise (view from top of machine downwards) .

Hi,

If You want to invert the rotary direction of the RA's just in transformation You have to modify the parameter set of RA-orientation.

E.g. for RA #1 in Trafo 1:

MD24570 $MC_TRAFO5_AXIS1_1[0] = 1

MD24570 $MC_TRAFO5_AXIS1_1[1] = 0

MD24570 $MC_TRAFO5_AXIS1_1[2] = 0

==> inverted:

MD24570 $MC_TRAFO5_AXIS1_1[0] = -1

MD24570 $MC_TRAFO5_AXIS1_1[1] = 0

MD24570 $MC_TRAFO5_AXIS1_1[2] = 0

for RA #2: parameters ....AXIS2...

MD24572 $MC_TRAFO5_AXIS2_1[x]...

the last two digits in the MD-identifier refer to the TRAFO number
