HIGH PERFROMANCE MACHINING TECHNOLOGY from MAL Manufacturing Automation Laboratories Inc Vancouver, B.C., CANADA http://www.malinc.com M.A.L. Products
MAL Inc. has two lines of Products to boost productivity of machining operations • ShopPro – Practical, easy to learn and use, integrated tap testing, chatter avoidance and diagnostics software for milling • CUTPRO – Advanced Simulation and Testing Software tool box to design, optimize, measure and diagnose machining operations, cutters and machine tools. Products
ShopPro/CUTPRO Instrumentation Set • Labtop computer • National Instruments NI9233 USB Measurement Box • Impact hammer and accelerometer • Microphone Instrumentation
3 Simple Steps in Using ShopPro • Enter material type and basic cutter geometry • Tap test the cutter on the machine or define dynamic parameters • Chatter stability lobes (vibration free speeds and depth of cuts), torque, power and material removal rates will be displayed instantly. • The noise from the machine can be recorded, and ShopPro provides automated diagnosis and advice. ShopPro Steps
Step 2 - Tap Test the tool to obtain machine stiffness ShopPro
Step 3- Machine Sweet Spots (depth of cut, spindle speed) are displayed with Torque, Power and MRR ShopPro
CUTPRO Machining Software Modules • MALTF – Advanced Tap Testing System • MALDAQ – Multi Channel Data Collection • MODAL – Modal Analysis with machine data base and tool tuning modules • MILLING – Advanced cutter design, optimization and simulation system for milling • TURNING, DRILLING and BORING Modules • SpindlePro – Finite Element Modeling and Analysis of Spindle Drives • Virtual CNC – A complete 5 axis modular CNC system design with drive design, sensors, amplifiers, friction, trajectory generation, interpolation and control modules CUTPRO Modules
