The Marposs supply consists of an IT support containing the software and relative documentation (referred to below as “the Product”).

The Product was developed for users with knowledge and skills in the use of software applications for machine tools, referred to below as “the User”. The Product is protected by Marposs copyright. The company reserves the right to make any changes considered necessary to any part of the Product in order to improve it. Marposs also reserves all rights relative to the Product with reference to modifications and processing on board the CNC or other data processing systems, as well as with reference to any form of transmis-sion and reproduction. Transmission and reproduction are only allowed after obtaining express authorization to use the Product on multiple units. Any persons breaching the above conditions will be prosecuted.

The measuring cycles are programmed for the acquisition/processing of measuring data generated by Marposs contact or laser probing systems. The cycles can be adjusted to specific application requirements directly on board the machine. The User must:

1.check that the parameters used in the cycles are compatible with the other machine functions;

2.check that the parameters are not changed or overwritten during execution of machine programs, causing malfunctions or dangerous situations;

3.not change the conditions for use of the cycles by changing the CNC operating modes.

The Product has been thoroughly tested. However, Marposs shall not be liable for the completeness and accuracy of data. When using the Product for the first time, the User must test the Product block by block, to confirm that it conforms for the specific application. After start up, the User must record the parameters and addresses substituted and any changes made, indicating the changes in the documentation. The software must be considered a semi-finished product to be integrated in the machine tool design, and as such Marposs cannot be held responsible for any damage to the machine resulting from:

1.incorrect use of the Product or programming errors

2.Product changes or application faults

Installation in the machine CNC implies acceptance of the above conditions and acknowledgement of the possible exclusion of the warranty in the event of damage.

Mida Lathe Touch Probe Systems Do to the growing popularity of “On Machine Probing”

Marposs S.p.A. has developed a new software package for

their mida machine tool probe systems. This new and

innovative software package was designed to help facilitate

the use of mida probe systems on a wide variety of lathe applications.

Mida Lathe Touch Probe Systems T ool Setting Software Features

Probe positioning movement is checked. If a collision occurs during protected positioning a flag is set and later checked at the beginning of the measuring macro. Input variables are checked for correctness of value and whether a required input is not programmed.

Any modal info that may need to be restored after a macro is completed is stored. Minimizes programmer input with appropriate defaults. Optional and default inputs are enclosed in brackets throughout the manual.

All tool motion is controlled by tool setting macros.

Calibration Capability.

Every measuring macro has the following functions:

Programmed tool offset change limit.

Checks for valid calibration data.

Multiple contacts made to assure repeatability.

Tool compensation.

Alarm messages.

Restore modal data.

Return to start point.

For lathe tool setting cycles (REQUIRES 8KB OF MEMORY)

Check your tool setting probe to see it is setup properly and in working

order. Check your installation records and documentation for probe activation method.?Turret probe test. This test assumes you have purchased an hardwired tool setting probe.

?Call any tool into cutting position. e.g. T0101

?Check that the tool probe is properly aligned with the machines axes.?If necessary issue the M-code(s) that activate the probe.?From MDI enter the following block. G31 U-20. F5.?The probe should move 20mm if functioning properly.

?Repeat the above MDI step and deflect the stylus during the 1" move. The probe should stop when deflected if functioning properly.

?

If probe is not functioning properly consult Marposs personnel for technical support.

For High Frequency systems only!

?

Make sure your High Frequency transmitter and receiver are properly aligned. The maximum separated distance between transmitter and receiver is 3mm gap. The maximum misalignment between centerline is 2mm. Both transmitter and receiver must be aligned parallel to each other. Any misalignment out of these specifications can cause unexpected results.

?From MDI enter the following block. G31 U-20. F5.?The probe should move 20mm if functioning properly.

?Repeat the above MDI step and deflect the stylus during the 20mm move.The probe should stop when deflected if function ing properly.?

If probe is not functioning properly consult Marposs personnel for technical support.

T ool Probe Calibration And Automatic T ool Measure Program

This program maybe used to datum the position of each of the four sides of the cube stylus.

This probram is used to measure X and Z tool length offsets.

MANDATORY INPUTS

USER OPTIONAL INPUTS

[C] = the offset change limit. (default is 0.01" (0.254 mm))

[X] = tool length to the edge of the tool in the X axis, in addition to the active tool

offset or the offset specified by the "T" code. This input is not required if the value of the tool length in the offset table for the X axis represents the whole length of the tool.[Z] = tool length to the edge of the tool in the Z axis, in addition to the active tool

offset or the offset specified by the "T" code. This input is not required if the value of the tool length in the offset table for the Z axis represents the whole length of the tool.[R] = the tool nose radius to provide positioning around the stylus. If variables is

vacant the default value is zero.

BEFORE USING THIS CYCLE:

WHEN D ATUMING:

1)Precede the Datum and Calibration subroutine call with the command to load a

reference tool of known length in both the X and Z axes. The known length in the X and Z axes must be entered into the geometry offset registers for this tool or the X and Z variables.

2)#502 ...machine p osition o f X+ s ide o f t he s tylus. p reset w ithin 0.01" o r .254 m m.

#503 ...machine p osition o f X- s ide o f t he s tylus. p reset w ithin 0.01" o r .254 m m.

#504 ...machine p osition o f t he Z+ s ide o f t he s tylus. p reset w ithin 0.01" o r .254 m m

#505 ...machine p osition o f t he Z- s ide o f t he s tylus. p reset w ithin 0.01" o r .254 m m

3)Program a subroutine call for each side of the stylus to be calibrated. The G65 sub-

routine call line must be preceded by a call to load the correct tool and geometry offset.

WHEN D ATUMING

1)When measuring: 502-505 must have been set by a previous datum cycle.

2)Make sure that all tooling in the setup has either valid geometry offsets obtained by

previous probing or by manually measuring and entering into the proper geometry offsets. Geometry offsets are actual X and Z lengths of the tools.

3)Program a subroutine call for each tool to be measured including entering the tool

orientation number (variable ‘S’). The G65 sub-routine call line must be preceded by a call to load the correct tool and geometry offset.

Semi Automatic T ool Measurement Program

This program automatically updates the X and/or Z axes tool geometry offsets for each tool measured.

MANDATORY INPUTS

USER OPTIONAL INPUTS

[A] = selects the calibration or tool measurement cycle.

If A is not 1. or is omitted the tool measurement cycle is selected by default.A = 1. --- the calibration cycle is selected.

Marposs

HOW TO USE THIS CYCLE:

Manually position the tool to the probe stylus side you wish to use to measure. Program a subroutine (either in edit or MDI mode) to measure the selected tool. Include entering the axis and an incremental amount to touch the tool to the probe stylus.

WHEN CALIBRATING:

502 - 504 are set automatically

“T” must be programmed

Use a qualified tool to calibrate

The X and Z tool offsets for the qualified tool must be stored in the offset location identified by the “T” input.

Where calibration is used the “T” code must contain the actual accurate tool geometry.

WHEN MEASURING:

The tool offset identified by the “T” input will be automatically updated. EXAMPLE:

G65 P9016 T3. A1. X-20.

Calibrate X+ side of cube using tool offset 3 as a qualified dimension.

G65 P9016 T4 X-20.

Attempts to measure tool by moving X-20. mm. If succesfull tool offset 4 is modified.
