Products \ Machine Tool Probe \ Easy Probe

EasyProbe software cycles are designed for use by machine tool operators for simple job set-up and measuring tasks on machining centres. The software can be easily configured, using a supplied install utility, to suit the machine tool configuration.

Probing can either be through use of the machine tool handwheel / jog function with cycles run via manual data input, or through cycles written into a part program and run automatically.

• Simple programming - EasyProbe cycles require little programming skill to achieve simple probing tasks
• Part set-up - work offsets can be updated for accurate component positioning
• Measurement results and errors are stored in a macro variable list
• Angle find macro can be used to update a 4th axis or enable G68 co-ordinate rotation

EasyProbe offers simple programming for basic workpiece set-up and part inspection tasks.

The angle of a surface can be found by running two single surface measure routines, the second with an 'A' input to calculate the angle between the two points.

The angle can then be used to update a 4th axis or enable G68 co-ordinate rotation.

Example
G65 P9023 Y10.	Y- single surface measure P1.
G0 G91 X-50. Y15.	Move from P1 to P2. Use either the jog or handwheel mode.
G65 P9023 A160. Y10.	Y- single surface P2 measure to find the angle error. Stored in #144.
G68 G90 X0.R#144	Apply rotation.

This cycle is used to measure the feature width and centre position using four points parallel with the X and Y axes.

The error of size and centre position can be stored or used to update the relevant work offset registers.

This cycle is also used to calibrate the XY axis offsets of a probe and the radii of a probe stylus ball.

Example
G65 P9023 D50. S59. I50. J50.	Set the centre at X=50, Y=50 relative to G59 X0 Y0
