Target Design Conciliation & Application Review

Target application and engineering staff meets with customer to define overall machine performance requirements:

Number of axis

Axis performance requirement: machine through put, speed and load requirement for each axis, mechanical size constraints. Cost goals per machine axis.

Review of technology and cost comparisons: DC brush motors, Step motors, Servomotors and related drive for each motor technology.

Product Technology Selected

Target performed an extensive review of the performance requirements for each axis and selected the motor and drive required for each axis. Because of the aggressive manufacturing cost goals Step Motor technology was decided upon as the most cost-effective approach. Armed with detailed sizing data Target’s engineering staff had developed, the appropriate motors were selected for each axis. Danaher’s recently introduced CTP series step motors and the field proven P7000 series stepper drive was selected.

Design Implementation

Since this was a 13-axis machine the performance data was reviewed in an effort to use common motors on multiple axis. This minimized the number of different models required and greatly aided in achieving manufacturing cost goals. A prototype machine was built to validate the computer modeling Target had done.

Overall Success

Machine design went to manufacturing with only minor changes on two axis and manufacturing costs goals were achieved. In addition, during Target’s initial design, 3 critical performing axis were identified and alternately sized with Servo Motors. Due to the overall success on the entry level machine a higher through put machine is being offered based on the same product platform with only slight manufacturing changes.

Application Profile

Industry - Semiconductor OEM equipment manufacturer.

Machine Type - Surface mount circuit board screen printer.

Application Challenge - Product positioned as entry level machine dictated the need for low manufacturing costs while not compromising machine performance.
