A CMM must have sufficient capacity to match the size of the objects the user needs to measure. The bearing ways on many of the new brands of CMMs are exposed; therefore, it’s important that these ways are wiped clean daily or, at the very least, weekly. In the summer, condensation occurs within the airlines, and water permeates the CMM, which damages the bearings and short-circuits the electronics. Types of CMM Machines. Level the CMM axis to this 3-D line (for example, +Y). Have a look through our guide to CMM. © Quality Control Technology | Have a look at our beginners guide. More Info You can use PC-DMIS with your CMM to develop measurement routines and then run those routines to inspect your parts. Maintenance costs will be higher if the machine is placed on the shop floor, but often the convenience of that location will be worth it. Applications Use Of Coordinate Measuring Machine (CMM) For….. *Corresponding Author: Sutarman1 3 | Page Figure 2. We use it every day to qualify rapid prototypes and production parts that have complex geometries with tight tolerances. Controller and computer filters should be checked weekly and replaced if necessary. After the machine moves to its home position and stops, you are ready to start the tutorial's first step. One side of the bridge rides on a rail on the bed, and the other is supported on an air cushion or other method on the bed without a guide rail.
need to make sure the PC-DMIS computer can communicate with your CMM. If you need To start PC-DMIS in Online mode, from the Windows parameters to control the machine's speed and motion. The until the LED illuminates. When scales are exposed, it's also important to gently wipe them down with isopropyl or methyl hydrate, and we emphasize the word GENTLY! Here we discuss how to use a manual CMM (Co-ordinate measuring machine). zero position and enable the machine's parameters (such as routines and then run those routines to inspect your parts. Dirt and metal particles have a tendency to embed themselves under the bridge bearings, which causes precision issues and possibly motor drive problems later on. On some models, the button is here: The CMM needs to move to a home position. Flip the switch or turn the key to start the controller. CMM Startup and Homing Procedure for PC-DMIS Online. Start menu, locate the PC-DMIS Online mode. The key or switch is likely on the controller mounted on the back of the CMM or workstation. Bring the axis in to line and measure the reference elements to assure perfect alignment. Various types of probes are used in CMMs, including mechanical, optical, laser, and white light. The home position enables it to properly set the machine's For instance, hard-bearing machines excel on the shop floor. Power on the controller and start PC-DMIS. starts the machine, for example: Mach Start, Most CMM machine calibration will be accomplished with the use of an artefact, but for more demanding calibration, a laser interferometer can be employed. The machine will then take the measurements which are transferred to the computer software. the screen: Do a machine start (if needed), then press OK to home. to the next step: "Create Some models designed for the automotive industry can even measure targets larger than 10m (30 ft) in size. 3. Firstly, you will need to evaluate which measurements you wish to take, normally referring to drawings or a measurement plan. Construct a 3-D axis line between the circles. Hold it for several seconds You can use PC-DMIS with your CMM to develop measurement Click the OK to change your machine's parameters, see "Setting 2. These machines are often used during the inspection phase in the manufacturing process. workstation. Copyright © 2019 It's amazing how companies will spend many thousands of dollars on a new coordinate measuring machine, yet they will not invest in a power conditioner/battery backup system. Depending on the machine, the probe position may be manually controlled by an operator or it may be computer controlled. 20% of all breakdowns and maintenance costs are caused by poor air quality. Frobe The capacity of the CMM is the maximum size of the object or workpiece where CMM machine can accommodate. If your device isn’t listed, the help files are really useful. on/off key, or a small rocker switch. How to use a CMM: to use a manual CMM the operator would move the probe by hand or using the joystick to the part that requires inspection.
From the Application Options tab, tick the option for Measurements Input and CMM Data Import Click the OK button.
You can set numerous A coordinate measuring machine (CMM) is either a contact model that uses touch probes, a spherical object used to perform measurements, or a non-contact model, which uses other methods such as cameras and lasers.
