Rotary Table

For I++ interfaces, since there is no option in the Machine Interface Setup dialog box to set the rotary table's maximum speed, you must use the MaxTableSpeed entry in PC-DMIS Settings Editor. This is used exclusively for Technology Server version 1.5 for Wexlar CMMs.

ROTABSPEED Command

When you define a Move/Rotab command, the command uses the speed value set in the Rotary Table tab of the Parameter Settings dialog box (Edit | Preferences | Parameters). You can override this value to slow down or speed up the rotary table with the ROTABSPEED command.

For example:

STARTUP=ALIGNMENT/START,RECALIBRATE:USE_PART_SETUP,LIST=YES

ALIGNMENT/END

MODE/DCC

MOVESPEED/ 96

FLY/ON

FORMAT/TEXT,OPTIONS,,HEADINGS,SYMBOLS,;NOM,TOL,MEAS,DEV,OUTTOL,,

LOADPROBE/X5HD

TIP/X5HD, SHANKIJK=0,0,1, ANGLE=90

MOVE/ROTAB,30,SHORTEST,

.

.

.

ROTABSPEED/ 72

.

.

.

MOVE/ROTAB,60,SHORTEST,

.

.

.

ROTABSPEED/ 20

.

.

.

MOVE/ROTAB,77,SHORTEST,

.

.

.

In this example, the last five lines show the insertion of the ROTABSPEED command. The first instance speeds up the rotary table to 72 deg/sec, possibly to speed up the measurement process for a small part. The second ROTABSPEED command slows the rotary table down to 20 deg/sec, possibly for a larger part.

 

If you use the default value of 0 (zero) for the ROTABSPEED command, the rotary table's speed is proportional to the value set for the MOVESPEED command. This is necessary for backward compatibility prior to the implementation of the ROTABSPEED command.

For systems with stacked rotary tables, you need to account for both tables in the ROTABSPEED command, ROTABSPEED <wspeed>[,<vspeed>] where <wspeed> is table one and the optional <vspeed> is table two.

ROTABSPEED/ 50,40

An example of a system with a stacked rotary table is the Optive CMM for vision systems.
